とする調圧弁。 A first pressure supply source 1 having a pressure supply source 1 such as a compressor that supplies a predetermined pressure, a throttle valve 3 connected to the pressure supply source 1, and a first inlet 4 and partitioned by a diaphragm 5. chamber 6, and second chamber 7
When the pressure from the pressure supply source 1 is introduced into the first chamber 6 from the first inlet 4 through the throttle valve 3, a second inlet 8 is also introduced into the second chamber 7.
a bypass passage 9 for directly introducing the pressure from the pressure supply source 1 through the second chamber 7; It includes an on-off valve 11 for opening and closing the outlet 10 in accordance with the movement, and an actuator 15 connected to the outlet 10,
At the beginning of supplying pressure from the pressure supply source 1, the diaphragm 5 is moved upward to open the on-off valve 11, a predetermined pressure is supplied from the pressure supply source 1 to the actuator, and a predetermined period of time has elapsed. After that, the diaphragm 5 is moved downward to close the on-off valve 11 and the actuator 15 is closed.
A pressure regulating valve that is configured to stop supplying pressure to.
