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 first recess;
- an orbiting scroll intermeshed with said non-orbiting scroll to form a plurality of compression pockets therebetween, said orbiting scroll including first and second passages, said first passage communicating with one of said compression pockets, said second passage communicating with said first recess;
- and
- a bearing housing supporting said orbiting scroll and defining a second recess adjacent to said orbiting scroll, said second recess communicating with said first and second passages.
A compressor comprising:
- a non-orbiting scroll including a first recess;
- an orbiting scroll intermeshed with said non-orbiting scroll and including an end plate having a passage extending therethrough, said passage communicating with said first recess, said first recess intermittently communicating with a suction-pressure zone of the compressor via said passage;
- and
- a bearing housing supporting said orbiting scroll and defining a second recess containing pressurized working fluid biasing said orbiting scroll toward said non-orbiting scroll, said second recess intermittently communicating with said passage.
