Abstract:
A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit, the valve comprising: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 including an end plate and an intermediate plate having a center collar with an aperture; a flexible diaphragm having a sealing surface in contact with the collar to create a seal, an opposite surface, an aperture extending therethrough, an edge coupled to the intermediate plate and a small diameter hole providing fluid communication between the inflow chamber and an intermediate chamber defined by the intermediate plate and the flow cylinder; a plunger having a contact surface and an opposite diaphragm contact surface, the diaphragm contact surface creating a seal with the opposite surface of the diaphragm; a shaft having one end connected to the plunger and extending through the aperture of the diaphragm; a spring located between the end plate of the flow cylinder and the contact surface of the plunger; wherein 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, 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, and wherein 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.
