To provide a screw compressor with a small-sized simple structure capable of reducing quantity of oil flowing out of the compressor.
The screw compressor is provided with a main casing 1 including a male and a female rotor 6, a discharging casing 3 including a discharging passage 15 of compressed gas discharged from the rotors, an oil reservoir 19 collecting oil separated from compressed gas. A cylindrical oil separating space part 4 communicating to the discharging passage 15 is formed on the discharging casing and the discharging passage 15 is connected to a tangential direction of the oil separating space part 4. A discharging opening 14 is provided to communicate with the oil separating space part 4 and a cylindrical member 5 is provided coaxially to the oil separating space part 4. The oil separation space part 4 and the oil reservoir 19 are connected with a communication passage of smaller section area than section area of the oil separating space part 4.
