Claims

[Claims for Utility Model Registration] (1) A pair of screw rotors meshed with each other and rotatably supported are housed in a cylinder forming a part of the casing to form a rotor chamber, and a rotor chamber is formed below the rotor chamber. An oil tank is provided through a cavity for discharging air that directly communicates with the compressed gas discharge port, and a separator tank is disposed on one side of the oil tank and is arranged in parallel with the rotor chamber and communicates with the cavity. An oil-cooled screw compressor, characterized in that a pre-separator is disposed in the cavity so as to face the discharge air flow, and the pre-separator forms a detour and a swirling path for the discharge air flow. . (2) The pre-separator interposed in the cavity is vertically disposed in the cavity, and one end thereof has a convex curved surface that narrows the flow path of the discharged airflow and further guides and swirls the airflow. Claim 1
The oil-cooled screw compressor described. (3) A rotor chamber is formed by housing a pair of screw rotors that mesh with each other and are rotatably supported in a cylinder that forms a part of the casing, and a compressed gas discharge port and a direct connection are provided below the rotor chamber. An oil tank is provided through a communicating cavity for distributing discharge air, a separator tank is provided on one side of the oil tank and is arranged in parallel with the rotor chamber and communicates with the cavity, and the cavity is provided with a separator tank. An oil-cooled screw compressor characterized by having a ventilated oil separation plate arranged opposite to the discharge air flow.
