Claims

[Scope of utility model registration request]

In an oil-free compressor having a hydraulic-pressure converter that sucks in, compresses, and discharges gas using an elastic member such as rubber, and expands and contracts the elastic member using a working fluid pressurized by a piston, An automatic pressure regulating valve for use in an oil-free compressor, characterized in that an automatic pressure regulating valve that opens and closes depending on the pressure on the gas discharge side of the converter is provided on the working fluid discharge side, and the working fluid pressure in the converter is adjusted by the automatic pressure regulating valve. Pressure regulating valve.
