专利汇可以提供Stirling cycle heat engines专利检索，专利查询，专利分析的服务。并且A Stirling cycle engine comprises hot and cold variable volume chambers disposed in tandem and having inner, flexible, walls which are interconnected by a tubular regenerator. The centres of the inner walls of the chambers are concave with their concavities facing away from each other. The centres of the outer walls of the chambers are convex with their convexities projecting into the concavities of the inner walls. The arrangement keeps the hot and cold chambers well apart without having to provide an extra-long regenerator.，下面是Stirling cycle heat engines专利的具体信息内容。

权利要求

1. A Stirling cycle heat engine comprising hot and cold variable volume chambers inter-communicating through a regenerator disposed centrally between the chambers and attached to the chambers by way of a pair of movable inner walls each of which forms an inner end part of one of said chambers, the central portion of each inner wall being of concave form with the concavities defined by the central portions of the inner walls facing away from each other, the chambers also comprising a pair of outer walls each of which forms an outer end part of one of said chambers, the central portion of each outer wall being of convex form, with convexities defined by the central portions of the outer walls projecting into the concavities defined by the central portions of the inner walls.

2. A Stirling engine as claimed in claim 1 provided with a stationary structure adjacent the outer wall of the cold chamber so as to define a space therewith open to the atmosphere, wherein in operation of the engine, said outer wall is free to oscillate whereby heat is removed from the cold chamber by a pumping action resulting from variation in clearance between the said outer wall and said stationary structure disposed adjacent thereto.

3. A Stirling engine as claimed in claim 1 wherein, in operation of the engine, the outer wall of the cold chamber is free to oscillate and wherein means are provided connecting the said outer wall with transducer means whereby oscillation of the said outer wall causes said transducer means to generate electrical power.

4. A Stirling engine as claimed in claiM 1 wherein one of the outer walls is made stationary and the other of the outer walls is free to oscillate and wherein coupling means operated by oscillation of the said other outer wall are provided to feed back energy into the engine so as to maintain displacement of working fluid between the hot and cold chambers.

5. A Stirling engine as claimed in claim 4 wherein the said coupling means comprise non-positive coupling means.

6. A Stirling engine as claimed in claim 5 wherein the non-positive coupling means comprise actuator means connected to the said other outer wall so as to oscillate therewith, mechanical lever means connected to the inner wall adjacent said other outer wall and a flexible connection between the actuator means and the mechanical lever means whereby oscillation of the actuator means results in displacement of the last-mentioned inner wall by way of said flexible connection and said mechanical lever means.
