Abstract: A refrigeration system includes a compressor, an evaporator connected to a low pressure line of the compressor, a condenser, an expansion device, and a cooling circuit. The cooling circuit includes at least one coolant supply line to channel a coolant towards the compressor, at least one coolant flow channel defined by a housing of the compressor that channels the coolant towards a motor of the compressor, a coolant return line to channel the coolant towards the low pressure line of the compressor, and a damping chamber located between the coolant return line and the low pressure line of the compressor. The damping chamber includes a damping chamber inlet to allow the coolant to enter a damping chamber volume from the coolant return line and damping chamber outlets to allow the coolant in the damping chamber volume to enter the low pressure line of the compressor.

The first compressor includes a first shell, a first compression mechanism, and a first suction inlet through which working fluid is drawn into the first compressor. The second compressor includes a second shell, a second compression mechanism, and a second suction inlet through which working fluid is drawn into the second compressor. The suction manifold includes first and second arms. The first arm provides working fluid to the first suction inlet. The second arm provides working fluid to the second suction inlet. The second arm includes a first suction pipe, a second suction pipe, and a suction valve. The suction valve is movable between a first position in which working fluid is allowed to flow through the first suction pipe and a second position in which working fluid is allowed to flow through the second suction pipe.

Abstract: 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.

Abstract: A compressor may include a shell, first and second scroll members, a floating seal, a muffler plate, and a wear ring. The shell defines a discharge chamber and a suction chamber. The floating seal may sealingly engage the second scroll member. The muffler plate defines the discharge chamber and the suction chamber. The wear ring may sealingly engage the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber. The muffler plate may include an axially facing surface that contacts the wear ring. The axially facing surface may include an annular recess. The wear ring may at least partially cover the annular recess. The annular recess may provide clearance between the muffler plate and the wear ring to allow the wear ring to deflect relative to the muffler plate during compressor operation.

Abstract: 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.
