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.
