ABSTRACT:
An improved method of manufacturing a swash plate assembly for use in a compressor, fluid motor or similar device in which a plurality of pistons are connected, by means of connecting rods, to a swash plate which drives (or is driven by) the pistons. A plurality of ball ended rods of a predetermined length having a pair of split die-inserts positioned about the rod, each against one of the balls. The balls are positioned in a die means having a central core to locate their position and which die means securely maintains the inserts against each of the ball ends. About one ball end of the rod, a piston with or without a slot is cast and the opposite ball end, which is positioned in a mating swash plate socket, has a swash plate cast about it. The finished assembly is machined for overall length, surface parallel, and, angular and diametral relationships.
