を特徴とするセラミツクスピストン。 A piston head made of ceramics that is approximately disc-shaped and has a depression in the center on the piston body side, and a metal ring shrink-fitted to the outer peripheral surface of the piston body, and a piston made of resin with a metal piston pin cast inside. In a piston formed by welding the lower part of the ring and the upper parts of both ends of the piston pin, the outer diameter of the piston head on the piston body side is smaller than the top surface of the piston head, and the smaller diameter The piston body side wall surface of the circumferential groove provided on the top surface side of the outer circumferential surface of the ring and the bottom surface of the piston head are sandwiched by the circumferential groove provided inside the ring.
A ceramic piston characterized in that the ring is shrink-fitted to a piston head.
