Carrier 52C, P manual Rotary Compressor Components

COMPRESSOR

A cutaway view of the rotary compressor with key components labeled is shown in Figure 27. The motor stator is rigidly attached to the compressor shell. The rotor is pressed onto the eccentric shaft, which is sup- ported by 2 bearings. Both the discharge valve and dis- charge muffler are attached to the motor bearing. The

pump bearing provides a thrust surface for the shaft and the rolling piston. Compressed gas is separated from the suction gas by the vane. Discharge gas pres- sure and the vane spring keep the vane in contact with the rolling piston.
