Abstract: A guide rod, with a ball on its free end, extends radially from a compressor wobble plate with the ball and rod being positioned for longitudinal and arcuate travel in a guide slot of the compressor housing as a result of the wobble plate movement. An improved pair of spaced guide shoe members are positioned in the slot on opposite sides of the ball with the shoe members having concave recesses on opposing surfaces for retaining the ball therebetween. Collar portions are integrally formed in opposed relation on the shoe members' radially inner ends, with each collar portion having a cylindrical surface positioned in conforming bearing contact with the guide rod permitting limited pivotal movement of the shoe members about the axis of the rod. The collars further provide additional bearing surfaces preventing the radially outer portions of the shoe members from being canted into non-parallel orientation and thereby minimize undesirable wear of the guide slot faces.
