Abstract
A compressor may include non-orbiting scroll, an orbiting scroll, and a bearing housing. The non-orbiting scroll may include a recess. The orbiting scroll may be intermeshed with the non-orbiting scroll to from a plurality of compression pockets therebetween. The orbiting scroll may include first and second apertures. The first aperture may communicate with one of the compression pockets. The second aperture may communicate with the recess. The bearing housing may support the orbiting scroll and cooperate with the orbiting scroll to define a chamber therebetween. The chamber may communicate with the first and second apertures.
Claims20
A compressor comprising:
- a non-orbiting scroll including a recess;
- an orbiting scroll intermeshed with said non-orbiting scroll to from a plurality of compression pockets therebetween, said orbiting scroll including first and second apertures, said first aperture communicating with one of said compression pockets, said second aperture communicating with said recess;
- and
- a bearing housing supporting said orbiting scroll and cooperating with said orbiting scroll to define a chamber therebetween, said chamber communicating with said first and second apertures.
A compressor comprising:
- a non-orbiting scroll including a recess;
- an orbiting scroll intermeshed with said non-orbiting scroll and including an end plate having an aperture extending therethrough, said aperture communicating with said recess, said recess intermittently communicating with a suction-pressure zone of the compressor;
- and
- a bearing housing supporting said orbiting scroll and defining a chamber containing intermediate-pressure working fluid biasing said orbiting scroll toward said non-orbiting scroll, said chamber intermittently communicating with said aperture.
