Abstract
A compressor according to the present disclosure includes a shell, a main bearing housing disposed within the shell, a driveshaft supported by the main bearing housing, a non-orbiting scroll member coupled to the main bearing housing, and an orbiting scroll member rotatably coupled to the driveshaft and meshingly engaged with the non-orbiting scroll member. The non-orbiting scroll member forms a suction pocket and at least one circumferential groove. The orbiting scroll member forms a lubricant passage that delivers lubricant from a lubricant source directly to at least one of the suction pocket and the at least one circumferential groove.
Claims25
A compressor comprising:
- a shell;
- a main bearing housing disposed within the shell;
- a driveshaft supported by the main bearing housing;
- a non-orbiting scroll member coupled to the main bearing housing, the non-orbiting scroll member forming a suction pocket and at least one circumferential groove;
- and
- an orbiting scroll member rotatably coupled to the driveshaft and meshingly engaged with the non-orbiting scroll member, the orbiting scroll member forming a lubricant passage that delivers lubricant from a lubricant source directly to both the suction pocket and the at least one circumferential groove at different times.
A compressor comprising:
- a shell;
- a main bearing housing disposed within the shell;
- a driveshaft supported by the main bearing housing;
- a non-orbiting scroll member coupled to the main bearing housing, the non-orbiting scroll member forming a suction pocket and at least one circumferential groove;
- and
- an orbiting scroll member rotatably coupled to the driveshaft and cooperating with the non-orbiting scroll member to form a compression pocket, the orbiting scroll member forming an injection port in fluid communication with a lubricant source, wherein as the orbiting scroll member orbits relative to the non-orbiting scroll member, the injection port moves to a first position in which the injection port delivers lubricant to the suction pocket and to a second position in which the injection port delivers the lubricant to the at least one circumferential groove.
