Abstract
PURPOSE: To prevent the lowering of efficiency in a screw compressor to rotate a pair of screw rotors mutually engaged in a rotor chamber to compress gas by providing pressure-reducing chambers between oil supply ports of bearings and screw parts of rotors.
CONSTITUTION: A screw compressor is provided with a male and a female rotor with a male serew 25 and a female screw 26 mutually engaged to be supported by two central shafts 55 and 56 to be rotatable, and used to compress gas sucked from a suction port 3 by the rotation of both rotors and discharge through a discharge port 2. Here, lubricating oil supply ports 71 and 72 are opened on bearings 49 and 51 to support shaft necks of rotors near screw parts, while between these oil supply ports 71 and 72 and screw parts, annular pressure-reducing chambers 82 and 84 are provided to cover outsides of neck parts partly, and connected to a rotor chamber oil supply port 90 through connecting passages 86, 88, 73, and 93.
