Abstract
In a sealing mechanism for a reciprocation apparatus for use in a reciprocating 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.
Claims10
A reciprocation apparatus with sealing mechanism comprising:
- a chamber,
- at least one reciprocation member movably provided in said chamber,
- a sealing member disposed between said reciprocation member and inside wall of said chamber in which said reciprocation member moves,
- a first fluid room and a second fluid room defined by both sides of said sealing member, said inside wall of said chamber and said reciprocation member,
- a first flexible partitioning member and a second flexible partitioning member respectively partitioning said first fluid room and said second fluid room, respectively, and
- a fluid carrying means for carrying fluid between said first fluid room and said second fluid room and including:
- (a) a first and a second sub-chamber respectively connected to said first and second fluid rooms,
- (b) a first flexible partitioning member for dividing said first sub-chamber into two parts of a first sub-chamber and a first sub-fluid room,
- (c) a second flexible partitioning member for dividing said second sub-chamber into two parts of a second sub-chamber and a second sub-fluid room, and
- (d) a pump for connecting between said first and second sub-fluid rooms, and wherein
- said first sub-chamber is connected to a chamber divided from said first fluid room by said first flexible partitioning member, and
- said second sub-chamber is connected to another chamber divided from said second fluid room by said second flexible partitioning member.
