专利汇可以提供Hot gas engine专利检索,专利查询,专利分析的服务。并且In a Stirling cycle engine, a compressor pump pumps gas from the engine to a reservoir to decrease engine power. The compressor is of the differential piston type with a free piston with controls alternating the working gas pressure on the two sides of the piston to maintain high and low pressures operating a pump for storing working gas in a reservoir under pressure.,下面是Hot gas engine专利的具体信息内容。

1. A hot gas engine having a working space with a charge of working gas therein under varying pressure comprising in combination, means pumping working gas from the engine into a reservoir to decrease power comprising a cylinder having a free piston therein, conduit means connecting to opposite sides of said piston working gas from said engine respectively of higher and lower working pressures to cause the piston to move, valve means respnsive to the piston as it nears the end of its movement for alternating the pressures on different sides of the piston causing it to oscillate, and said means pumping gas further comprising pumping structure connected to the piston and to said working chamber to pump working gas into said reservoir by oscillation of said piston, and valve means controlling the flow of working gas to said piston to control the pumping of working gas from said chamber.
2. An engine as defined in claim 1 wherein said conduit means comprises two conduits with oppositely connected non-return valves coupled respectively therein, said conduits being connected between said working chamber and opposite sides of said free piston.
3. An engine as defined in claim 2 wherein the valve means comprises a reversing valve coupled in said two conduits between said working chamber and said piston.
