HEAT COMPRESSOR Russian patent published in 2002 - IPC

FIELD: compression and transfer of gases. SUBSTANCE: proposed compressor has cylinder, tubular displacer with built-in generator and radially inclined holes for connecting regenerator with cold and not spaces of cylinder, respectively. Displacer is set into operation by electric drive with rotor found on outer side of displacer, and stator arranged on cylinder. Cylinder has heat exchanger of heat carrier with heat insulation and coolant heat exchanger, gas main line with intake and outlet valves and ribbed radiator. Displacer with regenerator is provided with end face blanks with ring-shaped end faces and axial recesses and rectangular section springs fitted in recesses. Displacer is loaded by these springs relative to inner end face walls of cylinder. Threaded sections are found in near end face sections of displacer whose radius at these sections is smaller than that of middle part. Threaded sections forming ring clearances located, respectively, in cold and hot spaces of cylinder, are made on inner surface of near end face sections of cylinder. EFFECT: improved efficiency of heat compressors. 1 dwg
