FIELD: applicable in various branches of equipment for compression and transfer of gas. SUBSTANCE: the compressor has a cylinder and a movable ejector pump with ducts and a regenerator located between the hot space and the heat exchanger located between the hot space and the heat exchanger on the outer side of the ejector pump in a gap. The refrigerant heat exchanger and the heat-insulated heat-transfer agent heat exchanger are located on the cylinder end faces. The inlet and discharge valves are positioned in the outer main connected through the refrigerant heat exchanger to the cylinder cold space in its end face. The electric drive stator is located on the cylinder outer side, and the rotor- on the ejector pump body. The extended surface heat exchanger is positioned on the cylinder outer side between the stator and the heat-transfer agent heat exchanger. The ejector pump is closed with end-face shaped blanks. Rectangular section compression springs are installed in the ring-shaped end-face axial grooves of the blanks. The ejector pump is spring-loaded by the springs from the cylinder end-face inner walls. The inner end-face sections and the end-face outer sections of the ejector pump have threads (fins) with formation of gaps. The ducts are to be found between the regenerator and the cold space and pass on the outer side of the ejector pump. Ducts pass in the area of the rotor under it and the ejector pump. EFFECT: enhanced efficiency of operation of the heat compressors. 4 dwg |
