Abstract:
1. A water valve comprising: a chamber defining an inlet and an outlet; an anchor disposed in the chamber; a pull element engaged with the anchor; a sealing cylinder engaging the pull element; a membrane with a proximal surface facing toward the inlet and a distal surface facing away from the inlet, wherein the membrane defines a central cavity, that engages the sealing cylinder, and a continuous substantially radial surface surrounding and extending from the central cavity, wherein the central cavity is the only opening defined in the membrane; a fluid passage structure with an interior and an exterior, wherein the fluid passage structure originates approximate the inlet and extends through the central cavity defined in the membrane; in an anchor first position the pull element closes a small valve seat defined in the sealing cylinder and water flows through a bypass channel to engage the distal surface of the membrane; in an anchor second position, displacement of the anchor moves the pull element to open the small valve seat and water flows through the small valve seat through an interior of the sealing cylinder and out via the outlet; and in an anchor third position, the sealing cylinder is displaced by the pull element and opens a main valve seat such that water flows substantially from the inlet through the outlet.
