の給油装置。[Scope of claim for utility model registration] (1) Oil that works in conjunction with a means for closing the intake blocking valve of the compressor at startup to limit the amount of lubricating oil supplied to the compressor during no-load operation to less than that during full-load operation. The discharge chamber of the compressor is provided with a gas port that communicates with the pressure air tank and liquid tank via a check valve, and a liquid drain port located at a lower level than the gas port. The compressed gas in the mixed fluid of compressed air and lubricating oil discharged from the gas port is constantly pressurized into the pressure gas tank/liquid tank, and the lubricating oil is constantly pressurized into the liquid reservoir from the liquid drain port via a liquid drain pump. In the screw compressor configured as above, an oil supply passage is provided which communicates with the suction side shaft sealed chamber of the compressor from the primary side oil passage of the oil amount adjustment valve, and
An oil supply device for a screw compressor, characterized in that a throttling mechanism is provided between the shaft sealing space of the shaft sealing chamber and the suction side end wall. (2) The oil supply device for a screw compressor according to claim 1, wherein the throttle mechanism is provided between the bearing space and the suction side end wall. (3) The oil supply device for a screw compressor according to claim 1, wherein the throttle mechanism is provided between a suction side bearing space and a shaft sealing space of the compressor.
