Definitions

the invention relates to a vane pump for a compressible fluid, comprising a housing, which has a pump chamber, which rotatably has a rotor with at least one sliding element, wherein the housing has a bottom plate, a lifting ring, a thrust washer with at least one fluid inlet opening and at least one fluid outlet opening, a cover element and means for sound insulation, wherein at least one suction port, at least one fluid channel and at least one pressure port are provided, such that fluid is to be guided via the suction port, the pump chamber, the at least one fluid channel to the pressure port.
Such a vane pump is out of the DE 10 2006 058 980 A1 known.
This document discloses a compact vane pump that can be used, for example, in braking systems of motor vehicles. Other applications include transmissions, steering systems and active suspension systems of motor vehicles.
a cap-shaped silencer is provided which terminates the vane pump end.
this known vane pump has a compact design, it is necessary because of the increasingly complex engine concepts, additional units, such as a vane pump to run even smaller and more efficient.
the object of the invention is therefore to provide a vane pump, which has a high performance and a high connection variability with the smallest design.
the cover element has the at least one suction connection, the at least one fluid channel, the at least one pressure connection and the means for sound damping.
the cover element is disc-shaped, whereby a small vane pump length is ensured.
the check valve is designed as a spring-plate valve and arranged in the cover element.
the lid member is easy to mount as a unit.
a valve seat is formed in the area of the fluid outlet opening by the thrust washer. In this way, the dead space between the outlet opening and pump unit is reduced to a minimum, which has a positive effect on the power consumption of the pump.
the check valve is designed as an umbrella valve, which is fixed in the thrust washer. In this case, the lid may include a valve limit for the umbrella valve.
a further alternative embodiment is given by the fact that the check valve is designed as a membrane member that is arranged on the cover element.
the membrane organ can hereby be designed as a rubber membrane or spring steel, wherein the valve seat is again formed by the thrust washer.
the means for soundproofing advantageously have a porous molded part which is space-favorable upstream of the pressure connection as a silencer.
the means for sound insulation consist of a labyrinth-shaped configuration of the fluid channel, wherein the at least one fluid channel is formed such that the sound is refracted when flowing through the fluid channel by the fluid at the fluid channel.
the fluid channel can be designed siphon-like in order to retain contaminants or liquid components. In this case, discharge openings can be provided in the fluid channel in order to prevent the fluid channel from running to fullness.
the lid member made of plastic or aluminum.
FIG. 1 shows an exploded view of a vane pump 2 according to the invention in the present embodiment, the vane pump according to the invention is fixedly connected to an electric motor 4 forming the drive unit.
the vane pump 2 for a compressible fluid, such as air has a housing 6 defining a pump chamber 8.
a rotor 10 is arranged in the present case, five slide elements 12 rotatably.
the rotor 10 is arranged in known manner on a drive shaft 14 of the electric motor 10.
the pump chamber 8 is closed by a bottom plate 16.
the slide elements 12 are guided in a known manner along a cam ring 18 and generate in this way the desired negative pressure.
a thrust washer 20 At the electric motor 4 opposite end of the pump chamber 8 is closed by a thrust washer 20.
This thrust washer 20 has an inlet opening 22 through which the fluid enters the pump chamber 8 and, in the present embodiment, has two outlet openings 24, 26, through which the fluid leaves the pump chamber 8.
a cover member 28 having a suction port 30 and a pressure port 32.
the lid member 28 is made of aluminum.
two centering pins 34 are provided in the present embodiment, through which the individual parts of the housing 6 can be mounted in the correct fit. Screws 36 ensure secure attachment of the individual parts 16, 18, 20, 28 on the electric motor 4.
FIG. 2 now shows a perspective view of a first embodiment of the cover member 28, wherein substantially, the directed to the thrust washer side of the cover member 28 is shown.
the suction connection 30, which is adjoined by a channel 38, can be seen, such that fluid via the inlet opening 22 is known
the thrust washer 20 forms in the present embodiment, the valve seat for the spring-plate valves 40, 42 each consisting of a plate member 44 and a spring 46.
the plate members 44 are held by means of lugs 48 captive in the cover member 28 and pressed by the springs 46 under bias against the thrust washer 20.
About interruptions 50 which are provided between the lugs 48, the fluid under pressure, in the fluid passage 52 and from there to the pressure port 32.
the fluid passage 52 is formed in the present embodiment labyrinth, so that the sound waves of the outflowing fluid are broken and thereby the Noise emission is significantly reduced.
a recess 54 provides a siphon-like structure of the fluid channel 52, whereby impurities and / or liquid component are retained in each installation position.
FIG. 3 shows an alternative embodiment of the cover member 28. Again, the suction port 30 with subsequent channel 38 can be seen. Also, the check valves 40 and 42 correspond in structure and function to the above, with respect to FIG. 2
Each outlet opening 24, 26 of the thrust washer 20 is now assigned here a separate fluid channel 56, 58, each of which opens into a pressure port not shown.
the respective pressure connection is preceded in each case by a porous mold element 60, 62, which acts as a muffler.
the respective fluid channel 56, 58 could also be configured in a labyrinth shape.
FIG. 4 now shows the lid element FIG. 3 with an alternative check valve 64.
the check valve 64 is formed here as a diaphragm member made of spring steel, which is opened by the pressure applied to one or more outlet openings of the thrust washer 20 in a known manner.
a valve limiting element 70 is provided, which limits the degree of opening of the membrane member 64.
