Abstract

An air pressure regulator for adjusting the output pressure outputted from the main valve to a setting pressure by controlling the pressure according to the gas supplied/discharged from an electromagnetic valve, which is characterized in: detecting the output pressure, and driving the electromagnetic valve by a pulse width modulation signal when the pressure difference between the output pressure and the setting pressure is larger than the specified value, and driving the electromagnetic valve by a pulse width modulation signal when the pressure difference is smaller than the specified value.
