Abstract

To achieve a fluid control valve which can control the pressure of a pair of breather ports of a pressure apparatus by lowering the pressure of one of the pair of breather ports in accordance with an increase in pressure of the other of the pair of breather ports. A fluid control valve includes a pair of air-supply port chambers for receiving a supply of pressurized air; a pair of control port chambers which form a pair with the pair of air-supply port chambers and are connected to the pressure apparatus via the pair of breather ports; a pair of flow apertures which communicatively connect each of the air-supply port chambers with the control port chambers; a pair of nozzle passages which communicatively connect the pair of control port chambers to the atmosphere, respectively; a flapper assembly, having a pair of openable control surfaces opposed to the aperture ends of the pair of nozzle passages, which is movable between the pair of nozzle passages; and a flapper assembly moving mechanism which moves the flapper assembly to increase one and decrease the other of the distances from the aperture ends of the pair of nozzle passages to the pair of openable control surfaces of the flapper assembly.
