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 piston and rod assemblies are made by casting the piston around one end of a connecting rod which is formed with a ball at both ends, thus providing a ball-socket connection therebetween. The pistons are finish machined. A die-insert is utilized to locate the ball and rod prior to casting, and is thereafter moved along the rod to contact the other ball end. This insert thus serves to locate the rod section with the affixed piston in a mating socket of a swash plate die. The swash plate is cast about a plurality of such piston bearing rods to a carefully toleranced dimension. The swash plate end of the assembly is then finish machined.
