DE 3645083 C2 and DE 19923734 C2 show the suction silencing apparatus that is used for gas tight seal formula compressor, and this silencing apparatus is assembled into by a plurality of housing parts.This housing parts is welded together.
Summary of the invention
The present invention is based on the technical assignment of the assembly of simplifying air cylinder head structure.
By using this paper to begin described air cylinder head structure, wherein suck silencing apparatus and have housing, in this housing, adopt this valve assembly, this housing has positioning device, and this positioning device is determined the position of this valve assembly in this housing, thereby has solved this technical assignment.
Therefore, valve assembly is arranged on and sucks in the silencing apparatus.This has two advantages.Positioning device is located this valve assembly, so that the opening in the housing of opening in the valve assembly and suction silencing apparatus is consistent with highi degree of accuracy each other.In addition, the suction silencing apparatus can suppress to appear at the noise in the valve assembly.In many cases, this noise suppression effect surpasses the effect that only decay sucks the vibration in the gas.This housing can be a bowl-type for example.
Preferably, this suction silencing apparatus is arranged between this valve assembly and the cylinder head covering.This makes air cylinder head structure have compact form of implementation.In addition, by using this layout, can be with the housing made by the plastic materials of heat conduction rate variance as the insulator between cylinder head covering and the valve assembly.This cylinder head covering comprises that a discharge gas supplies to chamber wherein.After compression, to discharge gas and have the temperature of rising, heat passes to the inboard of compressor case via the cylinder head covering, and for this purpose, this cylinder head covering has the heat conductivity of the best of possibility.Yet the neutral position of this housing means that heat no longer is directly passed to valve assembly from the cylinder head covering of heat.
Preferably, this housing has outer confining wall and cover, and this cover has a recess, and this cylinder head covering is arranged in this recess.Therefore along circumferential direction, this cylinder head covering surrounds by sucking silencing apparatus on the part of its height at least.Therefore, can make the suction silencing apparatus have required volume, exceedingly not increase the size of air cylinder head structure.
Preferably, this recess has the bottom, and this bottom is provided with opening, and this valve assembly is connected with chamber on the inboard that is formed on this cylinder head covering through this opening.Therefore, can will discharge gas is transported in this chamber from valve assembly with not hindering.
Preferably, the outer diameter that has of this cylinder head covering is less than the inner diameter of this recess.Therefore, can keep the cylinder head covering only to contact with housing via supporting surface.Can avoid contacting between this housing and the cylinder head covering.Like this, can stop heat to pass to housing from this cylinder head covering.
Preferably, the interior confining wall that surrounds this valve assembly extends from cover.Therefore, the noise elimination volume of suction silencing apparatus is arranged between outer confining wall and the interior confining wall.Along other direction, this noise elimination volume is limited by cover and cylinder seat, and housing is pressed against on this cylinder seat.Interior confining wall surrounds valve assembly and maintaining valve assembly.Owing to should can more accurately cooperate by interior confining wall, so can realize sucking the hi-Fix of the valve assembly in the silencing apparatus in simple mode with the outside dimension of valve assembly.
Preferably, confining wall extends from the bottom of recess in this.Therefore, can on the side relative of this opening, locate this valve assembly with the cylinder head covering.This cylinder head covering forms the extendible portion of the folded system configuration that is formed by valve assembly subsequently.
Preferably, less than confining wall outside this, this cover has flexibility to confining wall along the direction extended length of compression cylinder base in this, so that should be pressed against on this compression cylinder base by means of clamp device by interior confining wall.By this simple mode, can make the noise elimination volume be pressed against on the compression cylinder base with enough tightnesss with interior confining wall and outer confining wall, the unnecessary geometry that does not press is a little determined.Roughly suck the housing of silencing apparatus fixing after, interior confining wall just is pressed against on the compressor.This provides good sealing for this silencing apparatus.
Preferably, this outer confining wall is provided with Sealing, and the sealing part is pressed against on this compression cylinder base.The sealing part can directly be molded in the form of lip packing on the end face on the outer confining wall.It also can have the form of degree of tightness part.Also can use flat seal between the housing that is arranged in the compression cylinder base and sucks silencing apparatus, the sealing part covers the surface of compression cylinder base at least in the zone of noise elimination cavity.In the later case, reduced to pass to the heat that sucks the suction gas the silencing apparatus from hot base portion (promptly compressing cylinder base).
Preferably, this valve assembly and this interior confining wall have the groove that the cooperatively interacts-protuberance geometrical construction as the location auxiliary member.Therefore, the purpose of interior confining wall no longer is limited to valve assembly is remained on correct position in the housing that sucks silencing apparatus.Groove-protuberance geometrical construction also makes valve assembly with respect to this housing location positioning at a predetermined angle.For example protuberance can be formed on the confining wall, projects on confining wall in the groove on the valve assembly.On the other hand, valve assembly also can be provided with protuberance, and respective slot is arranged on the interior confining wall.
Preferably, groove-protuberance geometrical construction forms asymmetric.Therefore, can guarantee that valve assembly only inserts with predetermined angular alignment relation with respect to housing.At first, this has simplified installation.The second, can determine the angular orientation of this valve assembly, so that the optimal path that is formed for sucking gas respectively or discharges gas with respect to housing.
Preferably, this compressor has a cylinder that has a front side fixed surface, and this front side fixed surface has the external frame identical with this valve assembly and is contained in this housing.Therefore, valve assembly not only is contained in the housing, and in exactly being contained in the confining wall, and interior confining wall also extends long enough, so that surround cylinder in the zone of fixing end face.This provides a plurality of advantages.The first, fixed valve assembly is with respect to the position of cylinder more accurately, and cylinder is kept by identical location auxiliary member with valve assembly.The second, mainly with regard to side load, suck silencing apparatus and be fixed on better on the compression cylinder base.
Preferably, this fixed surface is formed on the peripheral flange.Save material like this, that is, can keep total wall thickness of less cylinder.
Preferably, confining wall has extension part in this, and this extension part adds the thickness of this flange corresponding to the total height of this valve assembly.Therefore, cylinder is located with respect to the compression cylinder base vertically in simple mode.
When pressing this compression cylinder base on this flange is deviating from the side of this valve assembly, this is a particularly suitable.In this case, cylinder is located with respect to the compression cylinder base vertically in simple mode.
Preferably, confining wall has at least one opening in this, and this valve assembly has the suction gas channel that at least one radially extends.Therefore, suck gas channel and enter the chamber that surrounds by interior confining wall through this opening.Herein, valve assembly is arranged to more closely be surrounded by interior confining wall.Yet, because valve assembly has one or more suction gas channels that radially extend,, the gas that sucks arrives the compression chamber that sucks gas channel and compressor via the opening in the interior confining wall so having difficulty ground, this opening is with radially to suck gas channel overlapping.In addition, the advantage that has of the suction gas channel that radially extends is easily to separate and sucks gas and discharge gas.This has reduced again to give the heat that sucks gas from discharging gas transfer, and this has improved the efficient of compressor.In addition, no longer need to make suction gas channel and discharge gas channel to pass valve plate and retainer element, valve plate and retainer element are used to limit the unlatching of discharging gas valve and move.Therefore, bigger cross-section area can be used for discharging gas openings, and this also has discharging the advantageous effect of gas flow characteristic.
Preferably, at least one guide plate is arranged in the zone of this opening.For example the guide plate that extends from cover is used to make the suction gas stream along opening direction deflection, so that make that sucking gas preferably roughly radially meets with valve assembly.
Preferably, the front side of this housing has recess, and this recess only extends on the part of the width of this housing.At this stepped part or recess place, recess is arranged in housing, and it is used to hold the suction joint.On the one hand, this provides the space that is used to suck joint; On the other hand, the noise elimination volume of suction silencing apparatus is held in bigger, does not need to increase the outside dimension of compressor case.
Preferably, this recess has the shape of the semicylinder of accumbency; The front side of this semicylinder has the silencing apparatus inlet.This semicylinder can be more easily adaptive with the cylindrical shape that sucks joint.The volume of noise elimination cavity does not roughly reduce.
Preferably, flow deflector structure is arranged to relative with this silencing apparatus inlet in this housing.The guide plate of this flow deflector structure is for leading by sucking the suction gas that joint sucks along the direction of the opening of interior confining wall.Simultaneously, flow deflector structure has specific oil separation effect.A little oil particles that is carried by the suction air-flow can not be followed and be turned to and therefore be deposited on the surface of flow deflector structure.In outflow of the oil export outer side wall and arrival oil groove, this oil groove is arranged in the compressor case oil that separates from noise elimination cavity.
Preferably, this silencing apparatus inlet is surrounded by annular wall on the outside of this housing.By little moving, this makes that sucking joint keeps closely contacting with the outside that sucks silencing apparatus.When the corresponding supporting surface that sucks joint corresponding to the surface of ball-joint and form when having the spherojoint that sucks silencing apparatus, this is particularly advantageous.

Fig. 1 shows the longitdinal cross-section diagram through coolant compressor 1, and this compressor is arranged in the compressor housing 2.Coolant compressor 1 has the compression cylinder base 3 of carrying cylinder 4.In cylinder 4, piston 5 is arranged to removable, and this piston 5 is followed connecting rod 7 by motor 6 and driven.Piston 5 defines compression chamber 8 with cylinder 4, and when piston 5 is moved to the left (with respect to the observer of Fig. 1), refrigerant gas sucks in this compression chamber.
Enter compression chamber 8 in order to control air-flow, be provided with valve plate 9, this valve plate has two suction openings 10 (only showing in Fig. 2) and discharge aperture 11.Suck valve plate 12 and be arranged on facing on the side of cylinder 4 of valve plate 9, this suction valve plate has valve block 13 for each suction opening 10.This valve block 13 is formed on by means of punching press and sucks in the valve plate 12.Usually this valve block is arranged on the horizontal plane that sucks valve plate 12, that is, it is pressed against on the valve plate 9.Only when gas when suction opening 10 is inhaled into, valve block 13 just moves away valve plate 9, so that allow gas to pass through.When piston 4 carried out compression stroke, valve block 13 returned to the state that presses valve plate 9 once more.
In a similar manner, discharge valve plate 14 and be arranged on deviating from the side that sucks valve plate 12 of valve plate 9, this discharge valve plate 14 has the valve block (not being shown specifically) of expulsion valve.In order to limit moving of the valve block of discharging valve plate 14, be provided with retainer element 15.
On the side relative with cylinder head covering 19, interior circumferential wall 27 extends from the bottom of recess 25.
Opening 28 is arranged in the recess 25, and cylinder head covering 19 (exactly being formed in the discharge side 20 in the cylinder head covering 19) is connected with valve assembly 16 through this opening 28.
Cylinder head covering 19 has the opening 29 that a plurality of edges circumferentially distribute in its flange 26.Respective openings 30 also is formed on the parts of valve assembly 16.Cylinder 4 has peripheral flange 31, and this flange also has opening 32. Opening 29,30,32 is each other in aligned relationship.Fixing bolt can insert through these openings.Corresponding through hole 34 is arranged in the bottom 33 of recess 25, and corresponding fixing bolt can insert through this through hole.Opening 29,30,32 and through hole 34 are enough big, so that corresponding fixing bolt does not touch parts, flange 31 or the housing 22 of valve assembly 16.Other part is arranged to and described component alignment.
This can be by for example shown in Fig. 5.On interior confining wall, protuberance 35,36 is inwardly projection radially. Protuberance 35,36 is arranged to asymmetric, and promptly protuberance 36 is compared with protuberance 35 and had more radially elongation.Be provided with corresponding groove 37 in the parts of valve assembly 16 and in cylinder flange 31, when valve assembly 16 and cylinder flange 31 were inserted in the housing 22, this groove engaged with protuberance 35,36.Therefore, the parts 12,9,14,15 of valve assembly 16 are kept by interior confining wall 27 at first.All these parts all have round-shaped.Should surround a corresponding round chamber by interior confining wall 27.Like this, valve assembly 16 is directed on all sides.Protuberance 35,36 with make valve assembly 16 or its parts 12,9,14,15 each other and with respect to the relation of the housing 22 angled alignings that suck silencing apparatus 18 cooperating of groove 27.
Corresponding groove 38 also is arranged on the flange 26 of cylinder head covering 19, so that cylinder head covering 19 can be installed with the relation of predetermined alignment with respect to the housing 22 of valve assembly 16 and suction silencing apparatus 18.For mounting technique, this provides advantage.
Therefore, sucking silencing apparatus 18 is arranged between cylinder head covering 19 and the valve assembly 16.Therefore valve assembly 16 can be inserted into the state that assembles in the chamber of interior confining wall 27 inboards, perhaps inserts independently parts one by one.
Facing on the side of valve plate 9, the flange 31 of cylinder 4 is formed for the supporting surface of valve assembly 16.Interior confining wall 27 extends sufficient length along the direction of compression cylinder base 3, so that the thickness size of flange 31 still is positioned within the confining wall 27.
As shown in Figure 4, it is long slightly that outer confining wall 23 and interior confining wall 27 are compared extension, (these two walls all extend left in Fig. 4).Circumferential seal 39 is arranged on the outer confining wall 23.Sealing part 39 is put and is leaned against on the compression cylinder base 3.When the housing that sucks silencing apparatus 18 just placed on the compression cylinder base 3, interior confining wall 27 still had apart from the less distance of compression cylinder base one.The covering on of housing 22 that sucks silencing apparatus 18 is flexible to a certain extent, is fixed on the compression cylinder base 3 so that will suck silencing apparatus 18 by means of fixing bolt 40, and confining wall 27 was pressed against on the compression cylinder base 3 in this can guarantee.Noise elimination cavity 41 in being formed between confining wall 27 and the outer confining wall 23 is sealed on its whole border thus.
As shown in Figure 1, also be pressed against on the compression cylinder base 3 in installment state flange 31.Cylinder 4 is imported into from a side that deviates from motor 6 through this compression cylinder base 3.This will simplify assembling equally.By means of the peripheral flange 31 of cylinder 4, suck silencing apparatus 18 and also be fixed in addition on the compression cylinder base 3, in case stop bit is mobile.
Can clearly illustrate from Fig. 2 and Fig. 5 especially, interior confining wall 27 has two gaps 42 or opening, says on certain meaning, and this gap forms the outlet of leaving from noise elimination cavity 41.Before gap 42, be provided with guide plate 43, the gap 42 in this guide plate directs refrigerant is gone in the confining wall 27.These guide plates 43 have improved flow characteristic.
As Fig. 5 schematically shown in, valve assembly 16 has roughly the suction passage 44 that radially extends, this suction passage is formed by the recess in the retainer element 15 45 and (unshowned in Fig. 2) valve plate 9 and the cut-away 46 in discharging valve plate 14.Therefore, suction passage 44 extends between retainer element 15 and valve plate 9.Retainer element 15 makes suction passage 44 and discharge side 20 separate, and gives the suction gas that sucks from compressed discharge gas transfer so that prevent heat.In addition, retainer element 15 can be made by the material of heat conduction rate variance, is for example made by stupalith.In this case, prevent that further heat is from the suction gas of compressed discharge gas transfer to suction.
At place, an end, the housing 22 that sucks silencing apparatus 18 has recess, and the link 48 that links to each other with suction joint 49 is arranged on (Fig. 1) in this recess.In sectional view, this recess 47 has the shape of semicylinder, and is spaced apart so that cylindrical link 48 is arranged to.Recess 47 does not extend on the whole width of housing 22.Therefore the volume of noise elimination cavity keeps bigger.Link 48 has roughly spherical front side 50, and this front side is pressed against on the annular wall 51 of silencing apparatus inlet 52.This annular wall 51 can be centered on by other annular wall 53, and this annular wall 53 is from the further projection of this housing and as another protective equipment that prevents that oil from flowing out from this housing.
As Fig. 2 and shown in Figure 5, the flow guide structure 54 that has two guide plates 55 is arranged to enter the mouth 52 relatively with silencing apparatus, and this flow guide structure 54 leads for the direction of the guide plate 43 of the gas flow that enters noise elimination cavity 41 through silencing apparatus inlet 52 before the gap 42 of interior confining wall 27.In addition, guide plate 55 is used for the oil separation.A little oil particles that is carried by the suction air-flow can not be followed and be turned to.Oil particles rests on the surface of guide plate 55.The oil of Fen Liing flows out to get back in (not being shown specifically) oil groove from the opening 56 of noise elimination cavity 41 through confining wall 23 outside by this way, and this oil groove is arranged in the inboard of compressor housing 2.
The bottom 33 of the recess 25 of housing 22 is thinner.In assembling process, this zone is fixed between the retainer element 15 of cylinder head covering 19 and valve assembly 16.When this zone had relative flexibility, it was as the sealing between the noise elimination cavity 41 of discharge side 20 in the cylinder head covering 19 and suction silencing apparatus 18.
Certainly can use the Sealing that forms separating component, to replace the lip packing on the outer confining wall 23 of being molded into as shown in Figure 4.Also can use the flat seal of (not shown) in addition, it is separately positioned between compression cylinder base 3 and suction silencing apparatus 18 or compression cylinder base 3 and the flange 31, and covers this compression cylinder base 3 at least in the zone of noise elimination cavity 41.By using this Sealing, reduced to pass to the heat of the suction gas the noise elimination cavity 41 from the base portion of heat of compression cylinder base 3.
For fear of mobile noise and flow losses, all openings and the separatrix of passage all are rounded off, that is, for example the edge in the edge of the edge of suction opening 10 and discharge aperture 11 and gap 42 all is rounded off.
In unshowned mode, the flange 26 of cylinder head covering 19 can be provided with the circumferential protuberance of projection vertically in addition.This protuberance increases the rigidity of whole covering.This protuberance provides bigger heat-delivery surface in addition, so that the gas in discharge side 20 can be cooled quickly.
