ENGINE FOR CONVERSION OF THERMAL ENERGY INTO MECHANICAL ENERGY Russian patent published in 2013 - IPC F01K21/00 

FIELD: power engineering.

SUBSTANCE: internal evaporation engine comprises a source of heat, a recuperative heat exchanger, a working machine in the form of a chamber of alternating volume with a movable element, a refrigerator, a pump and an actuating medium in the form of fluid, at the inlet pipeline of which from the refrigerator into the chamber there is a pump and additionally a metering device, a movable element is connected with a consumer of mechanical energy, at the outlet pipeline there is a controlled valve, control of operation of which, and also the metering device, is coordinated with the position of the movable element relative to walls of this chamber. Connection of the movable element of the chamber with the consumer of mechanical energy is made as hydrostatic, and the chamber of alternating volume is arranged inside the tight chamber with supply and drainage nozzles of coolant and condensate extractor.

EFFECT: invention makes it possible to convert both high and low potential thermal energy into mechanical energy, including environment heat.
