Heat engine on the Stirling principle or the Ericsen principle

摘要

Heat engine (2) on the Stirling principle or the Ericsen principle, with (a) a pair of cylinders (4), which has a first cylinder (6), in which a cold piston (14) is capable of reciprocating, and has a second cylinder (10), in which a hot piston (16) is capable of reciprocating; (b) a flow connection (24) for the working gas between the first and the second cylinder (6, 10); (c) a cooler (20), a regenerator (22) and a heater (28), through which the flow passes in succession as the working gas flows from the first cylinder (6) to the second cylinder (10) and vice versa; and (d) a kinetic coupling (30, 50, 56) between the cold piston (14) and the hot piston (16) in such a way that the cold piston essentially lags one quarter of the movement cycle time behind the hot piston (16). At least in the cold piston (14) the ratio of movement stroke to diameter is less than 0.5; and the cooler (20) and the regenerator (22) are respectively arranged in a disc-shaped configuration inside the first cylinder (6).
