Stirling engine with a phase transition liquid-gas working fluid

摘要

The invention relates to the field of propulsion and engine volumetric displacement, in particular for engines operating at expansion and contraction of the mass of working gas which is heated and cooled in one or more cells are constantly communicating, such as engines operating on the Stirling cycle.;Technical result of utility model - increasing engine power density per unit volume of the working fluid when the working fluid pressure close to atmospheric pressure. This technical result is achieved by the fact that the claimed Stirling engine with a phase transition liquid-gas working medium, including the return cavity defined by the walls of the cold cylinder and displacement piston expansion cavity defined by the walls of the hot cylinder and working piston, cooler, intercooler and a heater, installed in the working medium lines connecting the return chamber and the expansion chamber, connecting rods connecting the working and displacing the pistons with the crankshaft disposed in the crankcase, the working fluid line connecting the cavity of return and the intermediate heat exchanger bypass the cooler and a cavity extension, and the intermediate heat exchanger bypass heater as well as necessary for the organization of the working of the engine body circulation direction of check valves installed in the highways of the working fluid cavities immediately before the return and expansion; It contains working fluid that changes its state of aggregation in the process of the engine operating cycle, wherein the working medium condensation takes place in the cooler, and the evaporation - in the heater, the volume of the return chamber less the volume of the expansion chamber, the heat exchanger as an intermediate heat exchanger instead of the regenerator, in the recuperator, heat is exchanged between the liquid and gas.
