COMPRESSOR WITH MOVABLE FLEXIBLE MEMBRANE Russian patent published in 2018 - IPC F04B45/04 

FIELD: refrigerating equipment.

SUBSTANCE: device can be used in the industrial refrigeration cycle with the condensation of the refrigerant, in the steam heating cycle, and also as a pump. Compressor with a movable flexible membrane contains a thermally insulated spherical body, devices and pipes for supply and discharge of the steam and the liquid medium, and also the devices and the pipes for drainage of liquid condensate formed during the compression of the steam. Contains a flexible heat-insulating and waterproofing partition. Membrane consists of three layers – the upper and lower waterproofing and heat-insulating and central reinforcing layer. Membrane repeats the inner surface of the upper or lower hemispherical part of the body and divides the inner part of the spherical body into two insulated parts. In the upper part of the pipe, steam is supplied and diverted. In the lower part, the liquid medium is supplied and discharged through a pipe installed from below. Invention also includes auxiliary systems and mechanisms improving the performance of this compressor.

EFFECT: increases the service life.
