圧縮機。[Scope of Claim for Utility Model Registration] (1) In an oil-cooled screw compressor in which a pair of male and female screw rotors that mesh with each other and rotate are housed in a casing, a lubricating oil recovery path from a bearing chamber on the discharge side of the compressor is provided. It opens in the cylinder wall corresponding to the working space after suction confinement partitioned by the seal line of the rotor, and connects the suction side bearing chamber of the screw rotor serving as the drive shaft with the oil injection passage to the compression working space, The oil-cooled screw compressor is further characterized in that an oil passage communicating with the bearing chamber is provided with a restriction, and a shaft portion on the suction action space side is provided with a shaft sealing device. (2) In an oil-cooled screw compressor in which a pair of male and female screw rotors that engage and rotate with each other are housed in a casing, the suction side bearing chamber of the screw rotor, which serves as the drive shaft of the compressor, is connected to an oil injection passageway to a compression working space. An oil-cooled screw compressor, characterized in that an oil passage connected to the bearing chamber and communicating with the bearing chamber is provided with a restriction, and a shaft sealing device is provided on the shaft portion on the suction action space side. (3) In an oil-cooled screw compressor in which a pair of male and female screw rotors that mesh with each other and rotate are housed in a casing, a bearing cover is installed between the suction side bearing chamber of the screw rotor, which is the driven side of the compressor, and the oil injection passage. An oil-cooled screw compressor, characterized in that the flange portion of the oil-cooled screw compressor communicates with each other through an annular groove recessed in the flange portion of the compressor.
