Between of the heating device and the cylinder is a gas accumulator provided, inside which there is provided a bumper wall for the separation of liquid optionally, in the gas accumulator can be via a separate circuit to the heater and are optionally [...] are and can be returned.

[0004] The problem of the invention is therefore, to create a piston-Heat-Device, the has a high efficiency and low maintenance in more cost-effective production is in operation.

[0005] For a device of the type mentioned above this task is solved thereby that the cooling device (capacitor) acting on the pistons of the units a (evaporator) the liquefied propellant gas evaporated liquefied propellant gas and the heater that between the cooling device and the heating device and a pump device for delivering the liquefied propellant gas is provided directly to the conduit between the heater and the cylinder that is connected a gas accumulator is provided in the interior of which optionally a bumper wall for depositing of liquid, wherein the liquid remains in the gas accumulator can be to the heating device and by way of a separate circuit and are [...] are returned.

[0006] Preferred embodiments of the invention are the subject matter of the subordinate claims.

[0007] by the element combination according to the invention is in the device that the cooling device is designed, so as to minimize to evaporate are achieved is designed to liquefy a is provided on the pistons of the units acting propellant gas and the heating device, for the liquefied propellant gas, and between the cooling means and the heating device a pump device for delivering the liquefied propellant gas, that for operating the cooling device and for operating the heating device existing temperature level rooms, about the for operating the pumping means with the aim of the body of a given Greenhouse-pressure downstream of the heater power required. The energy minimization is achieved in the device thereby according to the invention that the pump device promotes a liquid with the liquefied propellant gas, wherein because of the high density of the liquefied propellant gas, unlike the gaseous propellant gas a sufficiently high even in smaller dimensions and at low propellant gas-throughput [...]

impulse energy the pumping means is given. Downstream of the heating device is given a sufficiently high propellant gas pressure to evaporation of the propellant gas then, after, so as to operate the unit with two rotatably mounted piston in a cylinder with respect to one another.

A heating of the propellant gas in two or more successive steps in the process effected on the one hand and, on the other hand a good handling properties of gas mixtures having slightly different boiling points and low energy initiation of heat into the propellant gas an effective. A of the two heaters can be operated by means of a solar collector heated liquid from a advantageous here, wherein the second heater is suitable in particular in terms of their prevailing higher temperature, so as to be operated by means of a heated liquid from a solar collector.

[0010] In the case that two heaters are provided, the gas accumulator is preferably coupled with the first heating device. The coupling is here preferably such that in the gas accumulator collected with the aid of the first heater and of the separate circuit evaporation processbackled propellant gas can be supplied to any one.
