摘要： A fluid pressure responsive member is shifted in accordance with the pressure differential between two lines either one of which can be a suction line with the other line being a discharge line of a reversible compressor. The fluid pressure responsive member has an arcuate recess formed therein which serves as a secondary suction port which provides fluid communication to the offset cylindrical chamber from the suction line in accordance with the position of the fluid pressure responsive member. Because the porting is responsive to the pressure differential between the two lines, the changeover of the porting is automatic upon the reversal of the operation of the compressor.

摘要： A spool valve is located within the shell of a hermetic compressor unit and shifted by a solenoid valve to direct the discharge of the compressor through either of two lines through the shell. Depending upon the line used as the discharge line, the compressor is suitable for either heating or cooling and is the equivalent of a reversible compressor. Alternatively, a spool valve can connect the suction line of a compressor to either of two lines extending through the compressor shell.

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. The rolling piston through viscous friction or frictional torque frictionally engages a reversing disk and causes the reversing disk to move between two positions depending upon the direction of rotation of the rolling piston. The reversing disk has a slot therein which forms the suction inlet and is moved by rotation of the reversing disk so as to be in fluid communication with the plenum which is serving as the suction plenum at that time.

摘要： A fluid pressure responsive member is shifted in accordance with the pressure differential between two lines either one of which can be a suction line with the other line being a discharge line of a reversible compressor. The fluid pressure responsive member has a pair of arcuate recesses formed therein which serve as secondary suction ports which provide fluid communication to the elliptical chamber from suction lines in accordance with the position of the fluid pressure responsive member. Because the porting is responsive to the pressure differential between the two lines, the changeover of the porting is automatic upon the reversal of the operation of the compressor.
