    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 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 refrigerant system includes a compressor having a flow of compressor lubricant therein, the compressor compressing a flow of vapor refrigerant therethrough. An evaporator is operably connected to the compressor and includes an environment to be cooled via a thermal energy exchange with a liquid refrigerant in the evaporator. A vaporizer is receptive of a first flow of compressor lubricant and refrigerant mixture from the evaporator having a first concentration of lubricant. The vaporizer uses a flow of compressed refrigerant to separate refrigerant from the first flow. A lubricant sump is receptive of a second flow of compressor lubricant and refrigerant mixture from the vaporizer having a second concentration of lubricant greater than the first concentration. A heat exchanger is receptive of a third flow from the sump and uses evaporator suction gas to cool the third flow, thereby increasing its viscosity before urging the third flow to the compressor.

    Abstract translation: 制冷剂系统包括其中具有压缩机润滑剂流的压缩机，压缩机压缩蒸气制冷剂流过其中。 蒸发器可操作地连接到压缩机，并且包括通过与蒸发器中的液体制冷剂进行热能交换而被冷却的环境。 蒸发器接受来自具有第一浓度润滑剂的蒸发器的压缩机润滑剂和制冷剂混合物的第一流。 蒸发器使用压缩的制冷剂流从第一流分离制冷剂。 一种润滑剂油槽可接受第二流量的压缩机润滑剂和来自蒸发器的制冷剂混合物，其具有大于第一浓度的第二润滑剂浓度。 热交换器接受来自贮槽的第三流，并且使用蒸发器吸入气体来冷却第三流，从而在将第三流推到压缩机之前增加其粘度。

    Abstract: A compressor has an inlet port and a discharge port. The discharge port communicates into a resonator chamber. The resonator chamber includes a first stage resonator array and a second stage resonator array downstream of the first stage resonator array with a connecting passage intermediate the first and second resonator array. Each of the resonator arrays includes a pair of spaced resonator arrays sub-portions, with each of the sub-portions including a plurality of cells extending into a housing member, and have a bottom wall and an open outer wall communicating with the flow passage, with a plurality of orifices extending into each of the cells. The orifices have a smaller diameter than a hydraulic diameter of the cells.
