A bearing system for a compressor including an unloader at least partially received within a recess of a driveshaft. The unloader includes an outer surface that is engaged with a bearing. An inner surface of the unloader is curved such that the unloader is pivotable relative to the driveshaft unload forces on bearing caused by deflection of the driveshaft.

Bearing and unloader assembly for compressors

A compressor includes a shell and a main bearing housing positioned within the shell. The main bearing housing includes a scroll assembly positioned within the shell and positioned relative to a first cavity of the main bearing housing, the scroll assembly includes a non-orbiting scroll, an orbiting scroll, and a cylindrical hub, and a coupling positioned between the orbiting scroll and a fixed component and movable relative to at least one of the orbiting scroll and the fixed component. A first seal may be positioned between the orbiting scroll and the coupling, a second seal may be positioned between the coupling and the main bearing housing, and a third seal may be positioned between the cylindrical hub and the main bearing housing, wherein the main bearing housing and the orbiting scroll define a pressure cavity.

A compressor includes a shell, a first compression member, a bearing housing and a second compression member. The first compression member is rotatable relative to the shell about a first axis. The bearing housing is coupled to the first compression member and rotatable relative to the shell about the first axis. The bearing housing includes a first pin that extends therefrom. The second compression member is rotatable relative to the shell about a second axis. The second compression member includes a base plate and an arcuate-shaped first pin pocket. The first pin pocket is formed in the base plate and receives the first pin. The first compression member is moveable between a first position in which the first pin is engaged with a surface of the first pin pocket and a second position in which the first pin is disengaged from the surface of the first pin pocket.

A driveshaft assembly for a compressor includes an unloader assembly and a driveshaft. The unloader assembly includes an unloader and a counterweight. The unloader assembly is rotationally supported by a bearing. The unloader includes a flank surface that is slidably engaged with a flank surface on the driveshaft.

A compressor includes a compression mechanism, a driveshaft, and a motor. The compression mechanism is configured to compress a fluid to a discharge pressure. The motor is configured to rotate the driveshaft. The driveshaft is engaged with the compression mechanism and is fixed to rotate with at least a portion of the compression mechanism. The driveshaft includes a longitudinal aperture configured to receive the fluid at a suction pressure, and includes a flange that receives at least a portion of the compression mechanism. The flange and the compression mechanism define a fluid passage therebetween. The fluid at suction pressure is received within the fluid passage from the longitudinal aperture in the driveshaft.

Co-rotating compressor

A compressor may include first and second scroll members, 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.

A system may include a first compressor, a second compressor, a first heat exchanger and a second heat exchanger. The first compressor has a first inlet and a first outlet. The second compressor is a sumpless compressor and has a second inlet and a second outlet. The second compressor provides working fluid discharged from the second outlet to the first compressor. The first heat exchanger is disposed upstream of the second compressor and provides working fluid to the second compressor. The second heat exchanger is disposed upstream of the first compressor and provides working fluid to the first compressor.

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.

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.

Systems and methods for providing lubricant from a first compressor to a second compressor are provided. A control module receives a start command for a climate-control system having the first and second compressors, allows lubricant from the first compressor to flow into an inlet of the second compressor, turns the second compressor to an ON-mode, and prevents lubricant from the first compressor from flowing into the inlet of the second compressor after the second compressor has been in the ON-mode for a predetermined time period.

A climate-control system includes a working fluid circuit and a storage tank. The working fluid circuit has a first compressor, a first heat exchanger, a second heat exchanger, a flash tank, and a third heat exchanger. The first heat exchanger receives working fluid discharged from the first compressor. The flash tank is disposed downstream the first heat exchanger and includes an inlet and first and second outlets. The first outlet provides working fluid to the third heat exchanger disposed between the flash tank and the first compressor. The second outlet provides working fluid to the first compressor. The storage tank contains phase-change material that is thermally coupled with the second heat exchanger of the working fluid circuit.
