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 assemblies are made by casting the piston around one end of a connecting rod section which is formed with a ball thus providing a ball-socket connection therebetween. Mating spherical ends with through-bores to receive the piston connecting rod section are cast-in-place and captured in sockets within the swash plate. The connecting rod section of the pistons is mated to the through-bores of the mating spherical ends and are positioned in an appropriate fixture to a fixed final relationship. The connecting rod sections are secured to the sidewall of each through-bore by a means such as electron-beam welding to secure the overall length of the final assembly.

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 assemblies are made by casting the piston body around one end of a connecting rod section which is formed with a ball, thus providing a ball-socket connection therebetween. Other connecting rod sections are cast-in-place and captured in sockets within the wobble plate. With the connecting rod being made in two pieces, the section connected to each of the pistons and the section connected to the swash plate are positioned in a fixed relation to one another in an appropriate fixture. The two sections of each connecting rod are then secured to each other, such as by welding, brazing or crimping, to complete the assembly.
