Piston for fluid machines

摘要

Pistons (17), which are reciprocated by a swash plate of a compressor, have two separate parts joined together. Each piston (17) has a body (21) and a coupler (22). The coupler (22) is connected to the swash plate (16). The body (21) is made of thermosetting resin. The body (21) is molded to the coupler. Accordingly, the piston body (21) to be firmly connected to the coupler (22).
