PURPOSE:To reduce the number of parts items as well as to cool a compressor so efficiently, by feeding lubricating oil to fed to a screw compressor body via a hydraulic turbine, while driving a cooling fan of the compressor by means of rotation of the hyeraulic turbine. CONSTITUTION:Lubricating oil contained in the gas discharged out of a screw compressor body 1 is separated from the gas at an oil separator 2 and then spouted to the inside of an operating chamber of a screw compressor via an oil cooler 3 and a hydraulic turbine 4. At this time, rotation to be obtained out of the hydraulic turbine is transmitted to a fan ventilating the compressor and the oil cooler and thereby the fan is driven so that efficient cooling is made performable in consequence without using an electromotor or the like in addition.
