Description

 Valve and Verfanren for media removal from housings

The present invention relates to a valve and a

Method for removing media from housings and in particular for degassing and condensate removal in cases of accumulators preferred by vehicles and in particular vehicles with a hybrid or electric drive. Particularly preferably, the valve is used in the field of motor vehicles, but can also be used in other vehicles on land, air and water.

In cases of accumulators is usually the

Necessity, condensate arising in the housing

continuously dissipate, for which a Auslassoffnung is required with a relatively small cross-section. In addition, however, it must also be prevented that media from the outside via the Auslassoffnung enter the housing. These include in vehicles insoesondere splashing and thus registered dirt, z. Salt. Further, in such cases, there is a need to be in the housing

If a certain pressure value is exceeded, the resulting gas must be removed from the housing (emergency degassing). This must be done for rapid relief through an opening with a relatively large cross-section.

According to this knowledge, the above requirements were previously solved by separate means for condensate removal on the one hand and for Notentgasung on the other. The use of separate facilities has the advantage that the vote of the release torque in the emergency degassing

is not a problem. Furthermore, the entry of media m, the housing via the Auslassoffnung, in particular of

volatile media, as z. B. in a prescribed salt spray test (ASTMB 117, DIN 50021, DIN EN ISO 90227) are used, are largely avoided. The disadvantage is jeαoch that by the separate embodiment a Variety of components is necessary, associated with increased assembly costs and therefore higher costs.

In view of this, the object of the present invention is to provide a device, in particular a valve, and a method for removing media from housings, which have a simpler design with fewer components and thus are less expensive, but at the same time make it possible to meet the requirements for reliable discharge Both media (eg condensate and gas) to meet and the occurrence of other media (eg splash water, dirt, etc.) from the outside into the housing as far as possible.

This object is achieved by a valve having the features of claim 1 or a method having the features of

Claim 14 solved. Advantageous embodiments of

present invention are to be taken from the ünteranspruσhen.

The present invention is based on the idea to combine the aforementioned devices in one device, wherein a valve body for closing and opening an outlet opening to allow a discharge of a first medium (eg condensate) from the housing and an entrance of others To avoid media in the case

is additionally movable so that in an emergency situation, an opening with a large cross-section is released and another other medium (eg, gas) can be quickly removed from the housing.

Accordingly, the present invention proposes a valve for media removal from housings, in particular for degassing αnd condensate removal in cases of accumulators preferably from vehicles. This comprises a directly or indirectly on the housing existing valve mounting area, for example. In the form of a housing to be attached to the frame. This frame preferably surrounds an opening provided in the housing, via which a Fiuidverbindung between the The frame preferably surrounds the opening completely and can be connected directly or indirectly to the housing, for example, in the case of an indirect connection, a later explained seal may be interposed the valve according to the invention comprises a valve body which is movably engageable with a valve seat to open or close an outlet opening in fluid communication with the interior of the housing, for which purpose the valve body is interposed relative to the frame

Closed position and an open position movable. This movement preferably takes place exclusively translationally. But they are also rotational or combined

translational and rotational movements conceivable. In the closed position, the valve body closes one

Discharge opening tight. In other words, the valve body is in contact with the associated valve seat. From this position the Ventilkorper is movable to a first open position in which the Ventilkorper is lifted from the valve seat. In the open position, a first medium, in particular a liquid medium, preferably a condensate aas the housing abfuhrbar. Insofar as a liquid medium is to be removed, the valve must be provided in the bottom of the housing, i. H. the frame is to be fixed on or in the area of the bottom of the housing. In addition to the valve body, the valve according to the invention further comprises a flap which is at least mounted in the frame in such a way that the valve body moves away from the connection with the housing for discharging a second medium, in particular a gas

Open position is movable. In the second open position, the valve according to the invention releases the opening provided in the housing with a sufficiently large cross section, so that rapid removal of the second medium from the housing is ensured. By combining the functions in one component and using the same opening in the housing to focus two different media out of the housing, it becomes possible to control the number of components and assembly steps required for media removal for such housings

Reduce facilities. As a result, the present invention, while retaining the desired advantages (see above), enables to reduce costs. In addition, all functions are independent, from the housing, which no tolerance or positioning problems arise and the vote of the release torque in the emergency degassing made easy.

Advantageously, the valve according to the present invention further comprises a locking device, which is provided in particular in the frame, wherein the

Locking device holds the flap in a normal position in which the valve body between the closed position and αer open position is movable, i. n. is not positioned away from the connection with the housing. If a certain predetermined pressure (overpressure) acts on the housing, which acts (directly or indirectly) on the flap, the locking device releases the flap so that it can be moved into the open position, ie. for example, can be moved or pivoted.

A pivotability of the flap can preferably be effected via a hinge in the frame, whereby an exact

Positioning of the flap in the frame is ensured and the flap is fastened captive to the frame

preassembled, which is advantageous to the later

described completely pre-assembled Ventilemheit leads. In this case, it is preferable to provide in the frame a latching hook which preferably engages or comes to a projection of the flap in order to open the flap in the flap

Normal position to keep. It is further preferred, on the side facing the Vorsorung a detent of the Rasthakers, but preferably on opposite sides, one

Schragflache arranged, which makes it possible to force the projection past the latch hook, wherein the

Snap hook and / or the projection, for example, away feathers. The latching hook is z. B. designed so that it springs away at a certain pressure acting on the flap to release the flap, whereby the projection on the

Snap hook can slip past. This kind of

Locking device allows an integral or

one-piece design with the frame or the flap, which leads to a further reduction of the components with the associated cost reductions. In addition, this type of locking device is in one

Injection molding {preferred thermoplastic injection molding) to produce.

In an alternative embodiment, the flap is held by one or more fixed stops arranged in the frame, for example in the form of the abovementioned latching hooks, and the flap is released by the acting pressure, without providing a hinge region which has a

Would cause pivotal movement, i. the flap will

preferably just squeezed out of the hard stops. So that the component is guided at the same time captive, the flap with the frame via a captive,

preferably in the form of a tether, be connected. In a particularly preferred form, the tether as

Soft component produced together with the frame and the flap in a two-component injection molding process.

Other suitable forms of captive securing can also be used, for example a device subsequently mounted for this purpose on the components to be connected or else an end stop arranged on the frame which limits the movement of the flap when a second open position is reached. To a sufficiently large opening cross section

ensure, in the case of pressing out of the flap of the frame in a preferred embodiment variant below the Normalst lluπg the flap designed such that it has additional openings and / or a cross-sectional widening.

According to a particularly preferred embodiment, the Ventiikorper automatically closes the Auslassoffnung at a pressure in the direction of the connection with the genoa. As a rule, only a very small pressure acts on the Ventiikorper, so that it is preferable to design the Auslassoffnung with the smallest possible cross-section. This makes it possible to keep the sealing surface small, whereby only a very small pressure on the seal must be exercised to ensure a seal. In order to achieve this in an advantageous manner, the Ventiikorper and the flap are designed as separate components, the Ventiikorper guided to move between the closing pitch and the open position in the flap, d. H. is kept shut up. The flap must be able to release the opening provided in the housing in order to be able to release it only in the open position or to be able to release it substantially completely

Close normal position. The decoupling makes it possible to provide a smaller Auslassoffnung than the opening in the housing, which leads to the advantages mentioned above, that the Auslassoffnung with a small

Cross-sectional area can be configured and thus the sealing surface remains small.

Thus, the Ventiikorper and the flap in the movement of the Ventilkorpers between the closed position and the open position, in particular the open position, not separate from each other, an end stop is provided, which prevents this. This can preferably be designed such that the flap has one or more projections which project to the Dichtkorper, while the Dichtkorper several m direction of the flap and preferably substantially parallel to the projections of the flap projecting projections which abut each other in the fully open position.

Moreover, in this embodiment, it is preferable to design the outlet opening m of the flap. This is preferably done in such a way that the outlet opening runs parallel to an upper side of the sealing body.

Furthermore, it is particularly in this embodiment

advantageous to provide a seal which completely surrounds the Auslassoffnung, at least in the closed position, wherein the seal provided on the Dichtkorper itself, d. H. connected to this or einstuckig in two-component injection molding can be designed. Alternatively, however, it is also conceivable to provide the seal on the flap (surrounding the outlet opening formed m the flap).

In particular, in this latter case, it may be preferred that the VentiJ body has one of the Auslassoffnung facing sealing surface, which decreases starting from the Auslassoffnung nacft outside, and the seal with at least one sealing lip (circumferential sealing lip) to versenen, the m in the same direction as the sealing surface is inclined. As a result, the pressure required for sealing can be further reduced, thereby further improving the seal.

As an alternative to the above-mentioned embodiment, it is also conceivable that the valve body itself forms the flap and is folded in both the translaton and the rotational direction in the frame. Thus, it is preferred that the Dichtkorper held by the closed position only and exclusively Translatonsch in the frame and guided to the open

Position is displaceable while he m the open

Position ends in a hinge and from there on only a pivoting movement is allowed (rotational). The

Design has in comparison to the separate embodiment, which has been described above, the advantage that no dirt between the flap and valve body occurs and thus a

Stopping the Venti] body or its translational movement is avoided.

To prevent the entry of volatile media, in particular as used in a salt spray test (ASTMB 117, DIN 50021 and DIN EN ISO 90227), via the outlet port, i. H.

between valve body and Äuslassoffnung or flap and opening m to prevent the housing, it is preferred that the Ventilkorper oαer the flap a perpendicular to the direction of movement of the Ventilkorpers zwiscnen the

Closed position and the open position extending substantially circumferential wall, which together with a circumferential side wall of the frame, a labyrinthine extension of the fluid path hm for connection to the

Housing, d. H. causes the Auslassoffnung or Gehauseoffnung. An extension of the fluid path impedes the entry of a medium through this path and further reduces the risk of it entering the housing.

Moreover, it is preferred that the valve body or the flap of the connection facing the housing have a sealing surface which slopes outwardly from the connection with the housing and provides a seal between the valve body and the opening in the housing or between the housing Flap and the opening in the housing seals and at least one, preferably circumferential sealing lip comprises. This is according to αieser embodiment preferably in the same direction as the sealing surface inclined, whereby less force on the sealing lip is necessary because the sealing lip additionally applies to the oblique (conical) sealing surface, ie the flat contact between the sealing lip and Dicntflacne in the direction of the fluid path is increasing. In these sealing lips as well as in the above-mentioned sealing lips an extension of the sealing lips represent an additional advantage. Possibly. could the sealing lips at this

Embodiment even in the open position slightly abut the sealing surface and were printed for removal of the first medium by deformation by means of this medium to the side. Also, several parallel Dichtiippen or one

spiral-shaped sealing lip conceivable.

Preferably, the valve according to the invention is included

Vehicles and especially motor vehicles used. Since the valve for condensate removal at the bottom of the housing

is arranged, it is often openly accessible on the vehicle underside. Thus, the valve body is automatically moved into the closed position and in particular the entry of water spray and associated Schmitz on the

Auslassoffnung or the opening in the housing is to be avoided in the housing, the Ventilkorper is preferably designed as a floating body and is by water pressure

 (Splash and / or a closed water surface) m moves the closing pitch. The closing pressure increases with increasing water pressure, so that an additional

Seal is ensured.

As already mentioned above, it is further preferred that all elements of the valve (frame, valve body, flap and seals (if present) are completely pre-assembled and can be connected to the housing as a valve unit, whereby the frame, flap and valve body can be made a dimensionally stable material, in particular a dimensionally stable thermoplastic, in particular PP and preferably PPGF 20 be formed, whereas the seals of a silicone 30 Shore or preferably when using a two-component injection molding, ie the molding of the frame, the flap and / or the Ventilkorper, may be formed from a TP as a soft component

Design in a 2K injection molding, in which the seals mitangespritzt as soft components to a hard component be, the loss of security of the components is increased in an advantageous manner and the number of parts required for pre-assembly further reduced.

In the event that the valve body as a standalone

Component is to be produced, this can be produced from any suitable material that has the required for the function density and shape stability, for example, from a foamed plastic material (z.3 styrofoam), ceramic or metal.

In addition to the valve according to the invention, the present invention also proposes a method for removing media from housings, in particular for degassing and condensate removal in the case of accumulator housings, preferably of vehicles. This comprises the selosttatige closing an outlet opening by preferably translational movement of a Ventilkorpers in a closed position, in particular of the above-mentioned

Ventiikorpers in which a Auslassoffnung is sealed, when a third medium is present at the Ventilkorper. Further, an automatic opening of the Auslassoffnung by preferably turn translational moving the Ventilkorpers is provided in an open position to a first medium, in particular a liquid medium and preferably a condensate from the housing via the Auslassoffnung to

permit, if no third medium is present at the Ventilkorpers. Finally, the opening of the Ventilkorpers of the Auslassoffnung is provided in a second opening state, which is preferably at a certain pressure in the housing of Stats and whereby substantially the entire cross-section of an opening in the housing, with the

Valve body is in fluid communication, released and a second medium, in particular a gas, from the housing

is dissipated.

In the drawings, like reference characters designate like or similar elements.

First, with reference to Figures 1 to 5, a first embodiment of the erfmdungsgemaßen valve

described.

FIG. 1 shows a detail of a housing 100 for ion batteries (accumulators) of a hybrid vehicle. The housing has a bottom 101 which is disposed on the vehicle lower side _^ nd exposed. In the bottom 101 is a

Well 102 is provided which receives a valve 10 according to a first embodiment of the present invention. The depression 102 is preferably closed by a flame and / or sorce guard (grid, fabric, fleece, etc.), not shown, which is fastened to the housing bottom 101 via the threaded bores 103 along the circumference of the depression 102. In the region of the depression 102, an opening 104 is formed in the housing 101. This opening 104 has a substantially rectangular cross-section with rounded corners, but can also others

Crossmoulding (eg round, oval, mereformig,

hourglass-shaped, etc.).

In Figure 2, the items of the valve are shown, which are also visible in Figure 3 in cross section.

The valve is essentially composed of a valve body 11, a frame 12, a flap 15, a first seal 16 and a second seal 17.

The valve body 11 is formed in two parts of a lower part 13 and an upper part 14 in the illustrated embodiment. The parts 13 and 14 are insoluble interconnected and form a cavity 18 (see Figure 3). The connection can be made for example by means of an ultrasonic welding process. By the honing chamber 18 of the valve body is designed as a floating body. Furthermore, the upper part has an opening (through-bore) 19, which serves to receive the second seal 17.

The frame 12 has an end face 22 which is designed in size and shape so that it completely surrounds the opening 104 of the housing 100. The end face 22 defines an opening 23 with preferably the same cross section as the opening 104 of the housing 100. Perpendicular to the end face 22 or to the plane in which the opening 23 is located, extends a circumferential side wall 21, at their rounded corners in each case openings 20 for Attaching the frame 12 are provided on the housing 100. Preferably formed emstuckig on the Senenward 21, two hinge halves 24 of a hinge for receiving the flap 15 are provided. On the diametrically opposite side is one

Locking device m arranged in the form of a latching hook 25 with a latching nose 26, wherein the latching hook 25 can deflect relative to the opening of the Scharmernalften 24 to the outside.

The flap 15 has a recess 27 for receiving the Ventilkorpers 11. Here, the valve body 11 m of the recess 27 translatoπsch senkrecnt added to the opening 23 slidably. A separation of Venzilkorper 11 and flap 15 is oewerkstelligt by projections 28 (end stop) on an inner wall 30 delimiting the recess 27. The projections 28 protrude toward the center of the recess 27 and are advantageously diametrically opposite each other. These projections beat against projections 29 of the

Ventilkorpers 11, projecting from a side wall 31 of the putty off. In this case protrude the projections 29 and 28th

preferably in a direction parallel to each other. The Stopping the projections 29, 28 takes place m the maximum open position of the Ventilkorpers 11 instead (Figure 4).

Furthermore, the depression 27 surrounds a collar 32, which at least partially runs completely around, which in the illustrated embodiment is interrupted by indentations 33 for receiving the openings 20 of the frame 12. Further, the flap has second hinge halves 34, which are brought into engagement with the first hinge halves 24 of the frame 12 and form the hinge for pivoting the flap 15. The hinge halves 35 are preferably

also formed in the circumferential collar 32. In addition, the flap 15 as a further part of

Locking device on a locking projection 35 which is in the normal position of the flap 15 with the latching hook 25 and the locking lug 26 m engaged (see also Figure 3). In the upper side 36 (FIG. 3) of the flap 15, an outlet opening 37 is provided. The top 36 also limits the recess 27th

The seal 16 has a circumferential collar 38 and an emstuckig extending from this sealing lip 40. In the collar 38 through holes 39 are provided, αie in their arrangement and during assembly with the holes 20 of the frame 12 are aligned. The opening 44 formed on the upper side 43 of the seal 16 corresponds to m shape and size in the

Essentially the opening 104 of the housing. The sealing lip 40 extends outwardly from the upper side 43, so that the opening 42 at the lower end 41 of the sealing lip 40 m is greater in its cross-sectional area than the opening 44.

The seal 17 is plate-shaped and we3 st a conical circumferential sealing lip 45 and a mushroom-shaped attachment member 46. The mushroom-headed

Attachment member 46 is m the opening 19 of the upper part 14 of the Ventilkorpers 11 received (see Figure 3). The

Sealing lip 45 is here circular to the circular Opening 37 adapted. The shape of the outlet opening 37 isr.

but not limited to a circular shape. Rather, oval or angular shapes would be conceivable. According to the shape of the Auslassoffnung 37 and the shape of the sealing lip 45 will be configured.

According to one embodiment, the upper and lower parts 13 and 14 of the Ventilkorpers 11, the frame 12 and the flap 15 of PP (density 0.9 g / cm ³ } and the seals 16 and 17 of silicone (about 30 Shore) formed Alternatively, it is also conceivable, the sealing lip 40 to the frame 12 and the seal 17 to the lower part 14 of the Ventilkorpers 11 in

To spray two-component injection molding. In this case, it would be preferable to use TP seals 16 and 17

Soft component and the frame 12, the flap 15 and the valve body 11 made of PPGF 20 as a hard component. The latter embodiment leads to a reduction of the components to be mounted to four, while, as shown in Figure 2, the present embodiment six

Requires components.

Referring to Figure 3, the arrangement of the individual elements to each other will be described.

First, the frame 12 is placed in Figure 2 on the circumferential collar 38 of the seal 16 so that the end face 22 and the upper side 38 in Figure 2 are in contact with each other. As a result, the sealing lip 40 projects through the opening 23 into the frame 12. Furthermore, here are the aligned

Openings 39 and 20. After connecting the elements 13, 14 to the valve body 11 unα imports of mushroom-headed

Mounting member 46 into the opening 19, the valve body 11 is used with the seal 17 m, the recess 27 of the flap, wherein the flexibility of the material of the flap 15 and the Ventilkorpers 11 allow the

Ventilkorper 11 under pressure in the recess 27th

ein- (rest) -bar is, wherein the projections 28 and 29 under Pressure glide past each other. Thereafter, the Ventilkorper Ii m the recess 27 translatoπsch and senKrecnt to the central axis of the Auslassoffnung 37 and the opening 23 and 44 movable ir> the flap 15 is added.

Anschnließend the flap is hung with the two hinge halves 34 m the first hinge halves 24 of the frame 12 and locked with the Verπegelungsvorsprung 35 on the locking lug 26 over.

After locking the sealing lip 40 seals against the

Top 36 of the flap 15 from. For this purpose, the

Upper side 36 in the region of the sealing lip 14 with a starting from the Auslassoffnung 37 to the outside and from the surface 36 running away inclined sealing surface 47 configured. By locking the sealing surface 47 is printed with strong pressure against the sealing lip 40, whereby the sealing lip 40, the m of a similar inclination, d. H. Also, starting from the opening 44 is inclined away to the outside, applies to the sealing surface 47, so that in the cross-sectional view m Figure 3, a long path between the opening 44 and the outer end 41 of the sealing lip is formed and the seal effect is improved.

As a result, a valve unit is formed in which all

Components can already be pre-assembled in Figure 2. This unit is then mounted over the mounting apertures 20 and 39 m correspondingly aligned fastening apertures in the bottom 105 of the recess 102 of the housing, where the opening 44 of the seal 16 with the opening 104 of the housing 110 is substantially

flees.

The function of the valve according to the first embodiment is explained below with reference to FIGS. 3 to 5. In the closed state shown in Figure 3 water pressure acts on the Ventilkorper 11, which is designed as a floating body. The water pressure is caused by splashing water on the one hand and when passing through a puddle and / or wet Fanrbahn to the floats pending water. As a result, the valve body is kept 11 m of its horizontal position and requires no further translational Funrung in the flap 15. A tilting is precisely avoided by the fact that the float remains through the water surface in a horizontal orientation. In the closed position, the valve body 11 is in the

Closed position, d. H. he sits on the valve seat, which is formed in the present case by the region of the recess 27, which the Auslassoffnung 37, d. H. the

Area around the outlet opening 37, surrounds. With this area, the sealing lip 45 of the seal is printed 17 m contact. The latter takes place by means of the valve body 11, which floats and the seal 17 or its sealing lip 45 prints against the region of the flap 15 surrounding the outlet opening 37. The outlet opening is tightly closed in this case. In addition, the gap between the wall 30 and the wall 21 or between the radially outer end face of the circumferential collar 32 and the inside of the side wall 21 αes frame is kept low to prevent volatile media easily up to the sealing lip 40 between the Can reach flap 15 and the housing 100. An entrance of volatile media up to this place becomes thereby

complicates and thus further increases the Dicntfαnktion. In this state, entry of volatile media, as used in particular in a salt spray test (ASTMB 117, DIN 50021, DIN EN ISO 90227) between the sealing lip 40 and flap 15 or valve body 11 with seal 17 and flap 15 is largely avoided.

If no such water pressure prevails, ie the valve body 11 does not float, it moves by gravity (as in FIG. 4) downwards to the fully opened position Position, wherein the projections 28 and 29 to each other

attacks. In this position, the sealing lip 45 dissolves from the area surrounding the Auslassoffnung 37

(Seal) and gives a Stromungsweg from the interior of the genaus uoer the opening 104, the opening 44, the

Auslassoffnung 37 between the top 14 of the Ventilkorpers 11 and the recess 27 bounding wall of the flap 15 in the recess 102 freely, as indicated by the arrows m Figure 4. This will be a reliable one

Condensate discharge from the interior of the housing 100 through the valve allows.

If gas is generated in the housing 100, the pressure in the

Increase interior of the housing. It creates an overpressure. From a certain pressure level a pressure release inside the housing must be possible. This is called, among other things as Kotcntgasung. In this case, the latching hook 26 of the latch 25 or the

 Locking projection 35 of the flap 15 designed so that in the case of a certain overpressure of the projection 35 and the locking lug 26 are disengaged and the flap 15 uoer the Scnarnier 24, 34 is pivoted about a pivot axis. The openings are 104 and 44 with a large

Released cross-section or its entire cross-section and allow the rapid removal of originated gas from the housing interior, as indicated by the arrows in Figure 5

is shown. This state is considered an open state

designates and provides the necessary emergency degassing.

The first embodiment described above makes it possible, with a small number of components (4 or 6), to combine the functions of condensate removal and emergency degassing in one valve. In addition, it allows the largest possible floating body with possible clamping Dicntflache, so that the pressure on the seal relative to the sealing surface can be made large. In addition, all functions are integrated in one unit and thus independent of tolerances between valve and housing, so that the stoppage of the release torque in the emergency degassing is straightforward.

Ie. any tolerance or positioning problems are eliminated. In addition, an exact positioning of the flap is ensured by the hinge 24, 34 and at the same time ensures the security against loss or integration of the flap in the Ventilemheit. Furthermore, through the

Design of the Dicntflache 47 and the sealing lip 40 of the pressure, which is necessary for sealing, be further reduced. Finally, the entry of cursory media is made difficult by the small gap between the individual parts or the labyrinthine execution. In addition, the sealing lips 40 could be further extended to provide additional protection.

A second embodiment of the valve according to the invention will be described below with reference to FIGS. 6 to 10. It will primarily be discussed the differences to the first embodiment and otherwise referred to the first embodiment.

The representation In FIG. 6, the valve 10 shown in FIG. 1 is similar to a valve 10 of a second embodiment mounted in a depression 102.

In FIG. 7, the individual parts thereof are shown in a perspective view. The seal corresponds to the

Essentially the seal 16 of Figure 2 and the frame of the frame 12 of Figure 2.

A seal 17 is not required here and the flap 15 and the sealing body 11 are combined in an element 50.

When the seal 16 and the Rahiren 12 were at the

Representation in Figure 7, the openings 39 and 20 omitted, but are of course similar to oei aer representation in Figure 2 provided. The valve body 50 (which simultaneously forms the flap) is composed of a bottom 13 or a

Lower part 13 and a top 14 forming upper part. The two parts are connected to form a cavity 18, preferably mitteis ultrasonic welding. By this embodiment, a float is formed. In order to increase the size of the floating body, the upper part 14 has a bulge 51 (see Figure 8), which enlarges the cavity 18. This bulge 51 protrudes into the opening 104 of the housing bottom The side of the upper part 12 facing the opening 104 can likewise be provided with an oblique sealing surface 47, as was explained above with respect to the first embodiment

Force {pressure through the valve body 11) is sufficient to achieve a seal between the upper part 14 and the sealing lip 40. Furthermore, the upper part shows the

Hinge halves 34, the locking projection 35 and the recess 27 of the flap of Figure 2. Also, the circumferential collar 32 is provided.

For mounting, as in the first embodiment, the second hinge half 34 is suspended in the first hinge half 24 and the valve body 11 is pivoted, the Verriegeiungsvorsprung 35 slides past the locking lug 26 of the latching hook 25. For this purpose, the locking lug 26 has a triangular in cross-section shape with Schragflachen 52 (see Figure 8 to 10) above and below. When vorbebeifuhren the Verriegelαngsvorsprungs 35 is thereby exerted a force on the latching hook 25 in order to pivot it outwards, so that the locking projection 35 can slide past.

In addition, carried out by the circumferential collar 32 which extends to the inside of the side wall 21 of the frame, a labyrinthine extension of the fluid path from the upper opening in FIG. 7 of the frame 12 between the valve body 11 and the inner wall of the housing wall 21 of the frame to the opening 44 of the seal or to the opening 104 in the housing. Furthermore, the gap between the end face of the collar 32 and the inside of the side wall 21 can be kept small to prevent ingress of volatile media between them

Keep sealing surface 47 and the sealing lip 40 as low as possible.

In addition, by latching the Ventilkorpers 50 in the frame 12, a valve unit is formed, which can be mounted pre-assembled together with the seal 16 at the bottom 105 of the recess 102 of the housing 100.

The mode of operation of this second embodiment is explained below with reference to FIGS. 8 to 10.

FIG. 8 shows the closed position of the valve body 50. This is done by water pressure during

maximum buoyancy of trained as a floating body

Ventilkorpers 50 a seal between the sealing lip 40 and sealing surface 47, so that a fluid inlet to the

Interface via the opening 104 in the interior of the housing is avoided.

If the water pressure drops, the valve body 15 lowers, whereby a gap between the sealing lip 40 and the

Sealing surface 47 is formed and condensate can be discharged through the opening 104, as shown by the arrows in Figure 9. Here, the valve body 15 moves with its hinged half 34 guided in the hinge half 24 translationally downward (see arrow in Figure 8) until it reaches the fully open position in Figure 9, in which the axis of the second hinge half 34 in the bottom of the hinge 24th rests and the projection 35 rests against the upper inclined surface 42 of the locking lug 26 of the latching hook 25. Should more condensate be present than through the Gap between the sealing lip 40 and the sealing surface 47 can escape, so the sealing lip can deform due to their inclination in addition to increase the gap.

If an overpressure arises in the housing 100, then the latching hook 25 springs outwards or the projection 35 upwards, so that the projection 35 and latching lug 52 can slide past one another. This is designed so that this scenario takes place at a certain pressure in the housing. By the

Pivoting the Ventilkorpers 50 is a large

Cross-section, substantially the entire cross section of the opening 104, released in the housing, so that a rapid gas discharge can take place from the housing. These

Emergency degassing is shown in FIG.

An advantage of this second embodiment is that a dirt entry between the translational

movable element and its leadership is not

is excluded, but the gap can be designed so that a setting of the translationally displaceable element is excluded. Otherwise, the valve of the second embodiment leads to similar advantages as the first embodiment, so that dispenses with a new mention.

It is understood that the present invention is not limited to the above-mentioned embodiments, but various modifications and variations can be made in light of the present invention. For example, with regard to the first embodiment, it is conceivable to design the seal 17 on the flap 15 instead of on the valve body 11.

On the other hand, it is also conceivable, the seal 16 am

Valve body 15 and the flap 15 to be fastened, so that the sealing lip 40 seals against a surface of the frame 12. Also, the seal 16 einstuckig in

Two-component injection molding to the frame 12 are configured. Furthermore, the cross-sectional shape of the opening not limited to a rectangular shape with rounded edges. Rather, also round, oval or other cross-sectional shapes are conceivable. The cross-sectional shape of the Ventilkorpers 11, 50 as a floating body is of

different maturity. In this regard, however, make sure that the float as large as possible and the sealing surface is kept as small as possible, so that the ratio between the required and existing pressure by the float is as small as possible. Also are

Of course, other sealing lip geometries or the provision of multiple sealing lips parallel to each other or as a spiral in the form of a labyrinth seal conceivable.
