ABSTRACT:
A ball and socket joint and method of making in which a piston, especially a compressor piston, and most particularly a piston for a compressor that pumps refrigerant, has a top wall and a depending skirt and is connected to the upper end of a connecting rod by a ball joint which is made by forming a spherical socket in the upper end of the connecting rod and riveting a ball to the underside of the top wall of the piston and forming the upper peripheral region of the socket of the connecting rod around the upwardly facing side of the ball. In practice, the ball is placed in the socket of the connecting rod and the rod is formed about the ball and then the ball is riveted to the piston.
