The engine has a recuperator preheating fluidic working medium e.g. water, from a feed pump by hot gaseous working medium from a turbine outlet. A thermal solar collector i.e. focusing parabolic trough, heats heat transfer medium i.e. heat transfer oil. An evaporator evaporates the transfer medium. The heat transfer medium passes through guide blades and a housing of an expansion turbine such that the guide blades and the housing function as a heat exchanger, where the expansion turbine is isothermally operated. A heat exchanger is integrated in the expansion turbine. Wärmekraftmaschine mit einem Arbeitsfluid, welches in einer Vorrichtung verdampft, entspannt und wieder kondensiert wird, bestehend aus mindestens einer Entspannungsvorrichtung, mindestens einem Verdampfer, mindestens einem Kondensator und mindestens einer Speisepumpe, dadurch gekennzeichnet, dass die Entspannungsturbine nahezu isotherm arbeitet.
