FIELD: power engineering.
SUBSTANCE: invention relates to power engineering. The thermodynamic machine contains a cyclical system, where the working fluid, in particular low-boiling working fluid, circulates alternately in a gas and liquid phase, heat exchanger, expansion machine, condenser and liquid pump. According to the invention in the product line of the liquid pump the partial pressure increase the pressure in the system, is applied to a liquid working fluid at the expense of adding of non-condensing auxiliary gas.
EFFECT: invention allows to prevent cavitation in the liquid working fluid.
