摘要： A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder (34) defining an inflow chamber (36) and an outflow chamber (38). The flow cylinder (34) an intermediate plate having a center collar (64) with an aperture (68). A flexible diaphragm (50) is provided with a sealing surface in contact with the collar (64) to create a seal. The diaphragm (50) has an edge coupled to the intermediate plate and a small diameter hole (114) providing fluid contact between the inflow chamber (36) and an intermediate chamber (40) A plunger (48) is placed on the diaphragm (50) to create a seal with the opposite surface of the diaphragm. A shaft (46) has one end connected to the plunger (48) and extends through the aperture (106) of the diaphragm (50). Pushing the shaft (46) causes the plunger (48) to separate from the diaphragm (50) creating fluid pressure on the diaphragm (50) contact surface to push the plunger (48) and causing the diaphragm (50) to separate from the collar (64) causing fluid to flow from the inflow chamber (36) through the aperture (114) to the outflow chamber (38).
