Abstract
A device for converting thermal energy into mechanical energy in a cycle process. A gaseous working medium is pushed from a hot space through a line containing a heater, regenerator and cooler through a cold space and thereafter pushed back through the same line into the hot space by a piston. The cold space is connected to a high pressure tank and a low pressure tank by two check valves operating in opposite directions. The pressure tanks are connected in turn to the inlet and the outlet respectively of an expansion engine.
