REVERSIBLE FIXED VANE ROTARY COMPRESSOR

摘要

The reversing of the direction of rotation of the motor of a fixed vane rotary compressor reverses the direction of rotation of the rolling piston (40). The rolling piston through viscous friction or frictional torque frictionally engages a reversing disk and causes the reversing disk (50) to move between two positions depending upon the direction of rotation of the rolling piston. The reversing disk has a slot (52) in it which forms the suction inlet and is moved by rotation of the reversing disk. Thus the slot is in fluid communication with the plenum which is serving as the suction plenum at the time.
