Claims

[Claims for Utility Model Registration] 1. In a compressor that suctions and compresses fluid through reciprocating motion of a piston, the head of the piston is divided into a base portion and an outer end portion, and the piston head is divided into a base portion and an outer end portion, and a portion between opposing end surfaces of the base portion and the outer end portion is At least one layer made of a material containing fluorinated ethylene and resin as a main component.
A compressor characterized in that a disc-shaped piston ring is sandwiched between the piston rings, the base portion and the outer end portion are connected to each other, and the outer periphery of the piston ring is in sliding contact with the inner surface of the cylinder bore of the piston. 2. The compressor according to claim 1, wherein the circumferential edges of opposing end surfaces of the base portion and the outer end portion of the head are formed into inwardly tapered surfaces.
-3 A practical use characterized in that a fitting recess is formed on one side of the opposing end surfaces of the base portion and the outer end portion of the head, and a fitting convex portion is formed on the other side, and the disk-shaped piston ring is formed as an annular plate body. A piston for a compressor according to claim 1 of the patent registration claim. 4. A utility model characterized in that an annular protrusion is formed on at least one of the opposing end surfaces of the base portion and the outer end portion of the head to prevent displacement of the disc-shaped piston ring in the radial direction. A piston for a compressor according to claim 1. 5. The compressor piston according to claim 1, wherein an annular stepped portion is formed on the periphery of the opposing end surface of the base portion of the head. −
