    摘要： A compressor 20 includes a cylinder block 28 having a first bore 30 and a cylinder head 32 overlapping the cylinder block. The cylinder head 32 has a second bore 34 aligned with the first bore 30. The second bore 34 is separated into a plurality of distinct regions including a suction region 42 and an economizer region 46. A plurality of valves includes a suction valve 50 selectively operable to fluidly couple the suction 42 region and the first bore 30, and an economizer valve 54 selectively operable to fluidly couple the economizer region 46 and the first bore 30.

    摘要： A vapor compression system (20) includes a compressor (22) that has a suction port (40) and a discharge port (42). A heat rejection heat exchanger (58) is coupled to the discharge port to receive compressed refrigerant. A heat absorption heat exchanger (72) is coupled to the suction port. A lubricant flowpath goes from the heat absorption heat exchanger to the compressor. A side channel pump (104) is located in the lubricant flowpath.

    摘要： A compressor (22) has a housing assembly (40) with a suction port (24), a discharge port (26), and a motor compartment (60). An electric motor (42) has a stator (62) within the motor compartment and a rotor (64) within the stator. The rotor is mounted for rotation about a rotor axis (500). One or more working impellers (44) are coupled to the rotor to be driven by the rotor in at least a first condition so as to draw fluid in through the suction port and discharge the fluid from the discharge port. An inlet guide vane (IGV) array (174) is between the suction port (24) and the one or more impellers (44). One or more bearings (66, 68) support the rotor (64) and/or the one or more impellers (44). A purge unit (400) has a vapor inlet line (410) for receiving a refrigerant flow and a return line (414, 417A, 417B) for returning a contaminant-depleted refrigerant flow. A supply flowpath (407A, 407B) for supplying refrigerant to the bearings extends from the purge unit.
