ABSTRACT:
A wobble plate compressor piston has a central aperture formed through its front surface, directly into the ball and socket joint that connects it to the drive plate. High pressure refrigerant and entrained lubricant mist are forced into the gap between ball and socket, collecting in a converging section thereof to form a liquid seal that prevents blow by of refrigerant gas and compression loss. The joint is better lubricated as a consequence, reducing stress on the connecting rod.
