Abstract:
In a compressed-fluid discharge control device (10), there are formed a valve chamber (68) communicated with a discharge channel (70) and supply channels (24, 66) for supplying a compressed fluid, and a pilot chamber (82) into which the compressed fluid is introduced from the supply channels (24, 66). A diaphragm valve (16) for communicating or cutting off communication of the supply channels (24, 66) and the discharge channel (70) seats on or separates from a valve seat (72) provided in the valve chamber (68). Pilot channels (78, 80) through which a compressed fluid supplied to the pilot chamber (82) passes are formed in the diaphragm valve (16). The compressed-fluid discharge control device (10) has a pilot chamber opening/closing valve for opening or closing the pilot chamber (82). The pilot chamber opening/closing valve comprises a solenoid valve (20) which is opened in response to energization thereof and closed in response to de-energization thereof.
