Abstract

See full text

In order to produce a single headed piston for a swash plate compressor, the following steps are used. First, a shaped block of metal is cast, the block including a plurality of unfinished piston structures which are aligned and integrated, each unfinished piston structure including a head portion and a neck portion which are axially spaced. Then, the head portions of the piston structures are machined. Then, an outer surface of the cast block is entirely coated with a fluorocarbon resin. Then, the coated outer surfaces of the head portions are ground, and then, each neck portion is machined to form two spherical recesses which face each other, the two spherical recesses being used for slidably receiving shoes. Then, the cast block is cut to separate the piston structures from one another.
