COMPRESSOR

A cutaway view of the rotary compressor with key com- ponents labeled is shown in Figure 32. The motor sta- tor is rigidly attached to the compressor shell. The rotor is pressed onto the eccentric shaft, which is supported by 2 bearings. Both the discharge valve and discharge 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 pressure and the vane spring keep the vane in contact with the rolling piston.
