HEAT COMPRESSOR Russian patent published in 2004 - IPC

FIELD: applicable in various branches of equipment for compression and transfer of gas. SUBSTANCE: the compressor has a cylinder, ejector pump with a built-in generator and radially inclined holes for connection of the regenerator to the cylinder cold a 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. The cylinder has an extended surface heat exchanger, heat exchanger of heat-transfer agent with a heat insulation, and a refrigerant heat exchanger, gas main with inlet and discharge valves. The ejector pump has end-piece blanks. On the side of the cold space the blank has a ring-shaped end-face axial groove with a rectangularestion spring installed in it. On the one side the spring is fastened on the cylinder end face in its cold space, and on the other side-on the bottom of the ring-shaped end-face axial groove so that the spring can operate in compression-tension. EFFECT: enhanced reliability, simplified construction. 1 dwg
