Abstract

PURPOSE: To improve the efficiency of gas compression and suction by a method wherein oil is supplied to a labyrinth part of a screw rotor to completely seal the gas.
CONSTITUTION: A supply port 13 is provided at a part facing to the labyrinth part 1b of the screw rotor 1 in a casing 2, and a part of the oil is supplied to the labyrinth part 1b of the screw rotor 1. When an oil feeding circuit is opened by the action of an oil control valve 12, the oil pressure-fed from an oil tank 7 is supplied from a supply port 2a of the casing 2 to a threaded part 1a of the screw rotor 1 and supplied to also the labyrinth part 1b of the screw rotor 1 from the supply port 13 through a branch pipe 14 which is a bypass circuit to completely apply a seal.
