HEAT COMPRESSOR Russian patent published in 2004 - IPC

FIELD: applicable in various branches of equipment for compression and transfer of gas. SUBSTANCE: the heat compressor has a cylinder, ejector pump with a built-in generator and radially inclined holes for connection of the regenerator to the cylinder cold and hot spaces, respectively. The ejector pump is actuated by an electric drive with a rotor located on the outer side of the ejector pump, and a stator located on the cylinder. Threaded sections are available on the outer sections with formation of annular gaps- on the inner surface of the cylinder end-face sections. The cylinder has a heat exchanger of heat-transfer agent with a heat insulation, refrigerant heat exchanger, gas main with inlet and discharge valves, extended surface heat exchanger. The ejector pump on the side of the cold space is rigidly coupled in longitudinal motion by its end-piece to one end of the cylinder packed rod, whose other end is coupled to the double-acting piston of the outer air cylinder. The air cylinder is rigidly installed on the cold end face of the cylinder with the aid of a bush with an inner sealing for the cylinder rod. Piston rings are installed on the piston. EFFECT: enhanced reliability and efficiency. 1 dwg
