摘要： A compressor may include first and second scroll members, a driveshaft, first and second bearings, and first and second Oldham couplings. The scroll members define compression pockets. The first bearing may define a first rotational axis about which the first scroll member rotates. The second bearing may support the second scroll member for rotation about a second rotational axis that is offset from the first rotational axis. The first Oldham coupling may include a first body and a plurality of first keys extending from the first body. The first keys may engage slots formed in the second scroll member. The second Oldham coupling is separate and distinct from the first Oldham coupling. The second Oldham coupling may include a second body and a plurality of second keys extending from the second body. The second keys may engage slots formed in a surface that rotates about the first rotational axis.

摘要： A compressor is provided and may include a shell, a motor assembly, a compression mechanism, a pump housing, and at least one pump. The shell includes a fluid disposed therein. The motor assembly is disposed within the shell and is drivingly engaged with a driveshaft. The compression mechanism is driven by the driveshaft. The pump housing is rotatably disposed within the shell for rotation relative to the driveshaft and relative to the shell. The at least one pump is rotatably disposed within the pump housing such that the at least one pump is in driving engagement with the driveshaft.

摘要： A compressor may include a non-orbiting scroll, an orbiting scroll, a drive shaft, a bearing housing and an annular seal. The non-orbiting scroll includes a first spiral wrap. The orbiting scroll includes an end plate having a second spiral wrap ending from a first side of the end plate and an annular hub extending from a second side of the end plate. The first and second spiral wraps cooperate to compress working fluid from a suction pressure to a discharge pressure. The drive shaft includes a crankpin received in the hub and drives the orbiting scroll. The bearing housing rotatably supports the drive shaft and may define a biasing chamber containing working fluid biasing the orbiting scroll toward the non-orbiting scroll in an axial direction. The annular seal may engage a diametrical surface of the hub and engage the bearing housing, thereby defining the biasing chamber.

摘要： A system may include a compressor, a heat exchanger, an expansion device, and first and second working fluid flow paths. The compressor may include a compression mechanism and a motor. The heat exchanger may receive compressed working fluid from the compressor. The expansion device may be disposed downstream of the heat exchanger. The first working fluid flow path may fluidly connect the heat exchanger and the expansion device. The second working fluid flow path may be disposed downstream of the heat exchanger and may fluidly connect the heat exchanger with the compressor. The second working fluid flow path may provide compressed working fluid to the compression mechanism and to the motor.

摘要： A capacity modulation assembly is provided and may include a control valve and a first line extending between the control valve and a suction pressure region disposed within a compressor shell, whereby the suction pressure region is in communication with a suction inlet gas fitting extending through a shell of a compressor. The capacity modulation assembly may additionally include a second line extending between the control valve and an intermediate pressure region disposed within the compressor shell, whereby the intermediate pressure region is in communication with compression pockets defined between an orbiting scroll and a non-orbiting scroll.

摘要： A compressor may include a shell, a first scroll, and a second scroll. The shell may include a first inlet, a second inlet, and an outlet. The first scroll may include a first end plate and a first spiral wrap. The second scroll may include a second end plate and a second spiral wrap, the first and second spiral wraps cooperating to define a series of moving compression pockets therebetween. The moving compression pockets decrease in volume as the moving compression pockets move from a radially outer position to a radially inner position. The moving compression pockets may receive working fluid from the first inlet at the radially outer position and provide working fluid to the outlet at the radially inner position. The second end plate may include a fluid cavity receiving working fluid from the second inlet and fluidly isolated from working fluid within the moving compression pockets.
