HEAT COMPRESSOR Russian patent published in 2007 - IPC F04B19/24 

FIELD: gas compression and pumping in different branches of technology.

SUBSTANCE: heat compressor includes displacing unit having built-in generator and radially inclined openings for communication of regenerator respectively with cold and hot cavities of cylinder. Displacing unit is driven by means of electric drive with rotor arranged in outer side of displacing unit and with stator arranged on cylinder. On outer near-end portions of displacing unit threaded zones are formed and on inner surface of near-end portions of cylinder threaded zones are formed, said zones form annular gaps. Cylinder includes heat exchanger of heat transfer agent with heat insulation, heat exchanger of cooling agent, gas main line with inlet and outlet valves, ribbed heat exchanger. Pneumatic springs of dynamic "spring-loading" of displacing unit are in the form of plunger cylinders mounted in its end caps and having reciprocal plunger pistons rigidly mounted inside cold and hot cavities on covers of cylinder of heat compressor. Working fluid of pneumatic springs is gas pumped by means of heat compressor.

EFFECT: simplified design, improved operational reliability of heat compressor.
