Abstract

PURPOSE:To eliminate the need for the check valve or the solenoid valve for exhaust and thus simplify the piping for an application to a dicushion circuit, by providing the one-directional delay communicating part. CONSTITUTION:The one-directional delay communicating part 26 is provided between the secondary pressure control room 11 and the secondary flow line 17. In case the secondary pressure is increased by the pressure of the room 11, the part 26 delays its pressure to transmit it to the room 11. Then the transmission of pressure to the room 11 is delayed by the part 26 when the secondary pressure is increased due to the dicushion or the like, and thus meanwhile no force functions to push up the diaphragm 9. Thus the exhaust valve is not opened. Accordingly the main valve 21 does not open to casue no reverse current of air from the flow line 17 to the primary flow line 16, thus eliminating the check valve. Furthermore a large-caliber secondary flow line exhaust valve 23 is provided at the exhaust port 14 to eliminate the exhaust solenoid valve. In such way, the piping is simplified.
