真空圧制御弁。 A first switching position in which the output port communicating with the rejection pad is communicated with a vacuum pressure port communicating with a vacuum source with pilot fluid pressure supplied to and discharged from the pilot chambers at both ends; and a first switching position in which the output port is communicated with a pressure air source. The valve member is driven to switch to a second switching position communicating with a pressure port that is connected to the pressure port, and closes between the ports in a neutral position, and when the valve member is in the first switching position, A flow path is provided to introduce the fluid pressure of the port into one pilot chamber to maintain the switching position, and to release the retention by supplying pilot fluid to the other pilot chamber, thereby detenting by the fluid pressure. A vacuum pressure control valve comprising a mechanism.
