AIR-COOLED COMPRESSION UNIT Russian patent published in 2002 - IPC

FIELD: oil-free compression units. SUBSTANCE: air-cooled compression unit has compression members made in the form of a pair of involute spirals, immovable and movable, forming compression chamber. Movable involute spiral is connected with mechanism of motion conversion. Common body is made in the form of a part of motion conversion mechanism in which motion conversion mechanism is located, and a part of body of compression members accommodating compression chamber, fan, pipe union - heat exchanger communicated with outlet of compression chamber passing into branch pipe which serves as outlet of connection with discharge line of compressor. EFFECT: increased intensity of heat removal of forced convective heat exchange from compression members and improved operating conditions. 1 dwg
