ABSTRACT:
A snap-action valve includes a housing defining a fluid chamber and a deformable membrane mounted within the chamber in alignment with an outlet opening in a wall of the housing. The membrane has an inner face exposed to the pressure within the chamber, and an outer face exposed to the ambient pressure via the outlet opening. The wall of the housing formed with the outlet opening is displaceable from the wall of the: housing formed with the inlet opening such that an increase in pressure in the chamber causes the membrane to deform to maintain the outlet opening closed until the displacement of the two walls exceeds the deformability of the membrane, whereupon the membrane opens the outlet opening with a snap-action to discharge a quantity of the fluid from the chamber and then recloses with a snap-action upon release of the pressure resulting from such discharge.
