Abstract

In a sealing mechanism for a reciprocation apparatus for use in a cycle engine having a reciprocation member (108), such as Stirling engine, oil or a fluid is enclosed in a fluid room constituted by a pair of flexible partioning members (112, 113) such as diaphragms or multiple bellows and side walls (111a, 111b) of a cylinder (111) or the like, and the fluid room is divided in two parts (114, 115) by a pressure-resistive sealing member (116) fixed to inside wall of a rigid partion wall (111f) to roughly seal the fluid allowing sliding motions of the reciprocating member therein.
