Abstract
In a heat engine that utilizes the energy content of a warm medium by a better exploitation of the isochoric changes of state in a cycle process having six changes of state (two isobars, two isochores and two isotherms) it is possible by means of the presently disclosed embodiments to minimize the constructive complexity. The heat engine comprises at least one pair of heat exchangers having one condenser and one evaporator. At least one working medium transfer device is arranged between the condenser and the evaporator of the pair of heat exchangers. At least one working engine driven by the working medium is provided. A conduit is provided between the condenser and the working engine and another conduit is provided between the evaporator and the working engine. Valve means are arranged between the pair of heat exchangers and the working engine and selectively open and close a fluid communication between these.
