DEVICE FOR THERMAL COMPRESSION OF A GASEOUS FLUID Russian patent published in 2018 - IPC F02G1/53 

FIELD: engines and pumps.

SUBSTANCE: group of inventions relates to gaseous fluid compression devices, and deals in particular with regenerative thermal compressors. Essence of the inventions is that the device comprises first chamber (21) thermally coupled to heat source (6), second chamber (22) thermally coupled to the cold source (5), piston (7) moved by rod (8), regenerator (9) which establishes a pneumatic connection between the first and second chambers, the stem being located in cylindrical socket (17) and the rod being guided in axial translational motion by linear guiding system (3) to guide the piston without contact with the jacket. In this case, cylindrical sealing ring (18) fixed in a cylindrical sleeve surrounds the rod with a very small radial clearance to restrict the passage of the gaseous fluid along the movable current. In addition, a monoblock cold crankcase with machined holes is opened, a heat shield in the hot crankcase and a self-actuated system with a returnable elastic means.

EFFECT: technical result is an increase in the service life of the device.
