A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder defining an inflow chamber in fluid communication with the inlet conduit and an outflow chamber in fluid communication with the outlet conduit. The flow cylinder includes an end plate and an intermediate plate having a center collar with an aperture. A flexible diaphragm is provided with a sealing surface in contact with the collar to create a seal. The diaphragm has an edge coupled to the intermediate plate and a small diameter hole providing fluid contact between the inflow chamber and an intermediate chamber which is defined by the intermediate plate of the flow cylinder. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface. A shaft has one end connected to the plunger and extends through the aperture of the diaphragm. A spring is located between the end plate of the flow cylinder and the contact surface of the plunger. Pushing the shaft causes the plunger to separate from the diaphragm creating fluid pressure on the diaphragm contact surface to push the plunger toward the end plate end, compressing the spring, and causing the diaphragm to separate from the collar causing fluid to flow from the inflow chamber through the aperture to the outflow chamber. Releasing the shaft causes the spring to decompress, forcing the plunger and diaphragm away from the end plate re-establishing the seal between the sealing surface with the collar preventing fluid flow from the intermediate chamber to the outflow chamber.
