Abstract
The invention relates to a motor vehicle vacuum pump having a pump housing surface, on which a noise absorption cap is mounted, said cap defining a noise damping volume.
Claims19
A motor vehicle vacuum pump having a pump housing surface defining an outer perimeter on which a noise absorption cap is mounted, the noise absorption cap having a rim coupled with the pump housing surface adjacent the outer perimeter of the pump housing surface, a noise damping volume defined between the noise absorption cap and the pump housing surface, wherein a double-sided adhesive connector is arranged between the pump housing surface and the rim of the noise absorption cap, the double-sided adhesive connector extending adjacent to at least substantially the entire outer perimeter of the pump housing surface about the noise damping volume and sealing the noise damping volume, the adhesive connector performing both a sealing function and a fastening function in addition to a noise decoupling function.
A vacuum pump for a vehicle, the vacuum pump comprising:
- a pump cover having a pump housing surface being generally planar and defining an outer perimeter;
- a noise absorption cap including a rim coupled with the pump housing surface adjacent the outer perimeter of the pump housing surface and extending continuously to define a noise damping chamber between the noise absorption cap and the pump housing surface;
- and
- a double-sided adhesive connector disposed between the rim of the noise absorption cap and the pump housing surface and extending continuously adjacent the outer perimeter of the pump housing surface about the noise damping chamber and sealing the noise damping chamber and decoupling noise between the pump housing and the noise absorption cap.
