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.
Claims2
A reciprocation apparatus with sealing mechanism comprising:
- a chamber having a side wall for supporting a sealing member,
- at least one reciprocation member movably provided in said chamber;
- a sealing member for slidably contacting with said reciprocation member;
- a first double bellows having a peripheral part and an inside part, said bellows contacting with said side wall at said peripheral part and with said reciprocation member at said inside part;
- a second double bellows having a peripheral part and an inside part, said bellows disposed at a postion opposing to said first double bellows said sealing member contacting with said side wall at said peripheral part and with said reciprocation member at said inside part;
- a first liquid room enclosed by said first double bellows, said side wall and said reciprocation member;
- and
- a second liquid room enclosed by said second double bellows, said side wall and said reciprocation member.
