Abstract: A compressor (20) comprises: a housing assembly (22) having a plurality of ports including a suction port (24) and a discharge port (26); a male rotor (30) mounted for rotation about an axis (500); a female rotor (32) enmeshed with the male rotor and mounted in the housing for rotation about an axis (502) for drawing a flow from the e suction port, compressing the flow, and discharging the compressed flow through the discharge port. The housing assembly comprises: a motor case (54); and a cover (60) bearing the suction port. The cover comprises a unitary piece forming: a mounting portion (63) mounted to an adjacent end (55) of the motor case, said adjacent end being large enough to pass the motor; and a fitting portion (62) extending to a rim (66) at the suction port and bearing an external groove (200).

Abstract: A compressor has a housing assembly having a plurality of ports including a suction port and a discharge A male rotor is mounted for rotation about an axis. A female rotor is enmeshed with the male rotor and mounted in the housing for rotation about an axis for drawing a flow from the suction port, compressing the flow, and discharging the compressed flow through the discharge port. A cavity group is between the discharge port and the male rotor and female rotor. The cavity group has a first member separating a plurality of cells and a foraminate cover member atop the first member.

Abstract: A refrigeration system includes a compressor for compressing a refrigerant, a condenser for cooling the refrigerant, an evaporator for heating the refrigerant, and a lubrication system for providing a lubricant mist to a movable component of the compressor. The lubrication system includes an ejector arranged in fluid communication with the compressor and the evaporator, wherein the lubricant mist is carried by the refrigerant to the movable component.
