ABSTRACT:
A variable capacity vane compressor has an axial pressure device for applying variable axial pressure to a rotary valve. The rotary valve plate locates in a rotary valve housing and changes the capacity of the compressor due to its rotary position. An actuator member rotates the rotary valve plate in response to varying pressure in the discharge and intake chambers. A control valve supplies a variable control pressure to the actuating member for moving the actuating member to rotate the rotary valve plate. An annular axial pressure chamber is located between the rotary valve housing and the rotary valve plate. A control pressure port leads from the control valve to the axial pressure chamber. A seal member within the axial pressure chamber applies an axial force on a bearing located on the rotary valve plate. The control valve which supplies variable pressure used to vary the actuator member position also supplies the control pressure to the axial pressure chamber.
