Abstract
An improved CV joint type of torque restraint for the socket plate of a variable capacity piston compressor. The inner and outer races of the joint have straight ball tracks arrayed along over lapping conical surfaces, with four balls captured therebetween. The inner race is fixed stationary and solid to the cylinder block, while the outer race is fixed to the socket plate. There is no provision for the inner race to shift axially relative to the compressor housing. When the socket plate changes its basic angle relative to the compressor central axis, the balls simply shift within the ball tracks to compensate.
