FIELD: mechanic engineering. ^ SUBSTANCE: invention is related to mechanic engineering and can be used to convert thermal energy into mechanical work. The invention can be widely used in transport and power industry using, for example geothermal sources, solar power and residual heat of internal combustion engines. Heat machine includes regenerator between cold and hot zones and no less than two closed spaces to displace working medium. Closed spaces are mechanically interconnected by their variable volumes and located in hot zone. No less than two coolers are positioned in cold zone. Coolers with equal and constant volumes are linked with reducing volumes of closed spaces in hot zone by means of parallel gas lines. Expanding volumes are interconnected by gas line. When maximum value is achieved, closed space is linked with the smallest reducing volume joined with all coolers through one of coolers to be replaced each cycle. Reducing space is then isolated before its minimum volume is achieved. ^ EFFECT: simplification of heat machine structure; improvement of weight and size indicators with simultaneous increase of efficiency factor; problem of fast working medium cooling is solved. ^ 1 cl, 4 dwg |
