COMPRESSION UNIT FOR AIR COOLING Russian patent published in 2002 - IPC

FIELD: compression units without lubrication. SUBSTANCE: unit includes compression units made in form of pair of involute spirals: immovable and movable spirals which form compression chamber. Movable involute spiral is connected with motion conversion mechanism. Common housing is made as part of housing of mechanism where motion conversion mechanism and parts of housing of compression elements are located; arranged in this part of housing are: compression chamber, fan, pipe union-heat exchanger connected with outlet of compression chamber changing into branch pipe connected with mechanical check valve which is used as outlet for connection with pressure line of compressor and is connected with electromagnetic valve which is used as outlet for communication with atmosphere. EFFECT: intensification of removal of heat from compressor components by forced convective heat exchange; improved operating conditions. 1 dwg
