Abstract

An assembly for providing socket plate torque restraint for a variable displacement wobble plate compressor is provided. Swing arms support a guide pin and allow for swinging motion to be directed to the pin. A translatable driving sleeve is attached to and rotates with the compressor drive shaft. The sleeve is formed with a cam section having a variable axial profile. An axially fixed follower cooperates with the cam section to generate the motion of the guide pin relative to the socket plate. The motion defines a motion of the socket plate which produces no inertial torques. The compensating torque restraint smooths the uneven driving action of the socket plate. The position of the cam section varies in relation to the displacement orientation of the socket plate, thus allowing precisely that socket plate motion, at all stroke positions, which produces no inertial torques.
