Abstract:
A flush valve has a relief valve including a stationary relief valve housing and an axially-translatable valve element. The axially-translatable valve element has an axial end that can be selectively translated to unseal an upper opening in a relief passageway through the stationary relief valve housing in order to permit fluid flow therethrough in order to initiate a flush cycle by the lifting of a diaphragm assembly. The axially-translatable valve element may include lead screw-like features which can be used to axially drive the axially-translatable valve element relative to the stationary relief valve housing to open or close the relief valve.

Claim (Index 1):
A flush valve comprising:\n a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet, the fluid passageway having a diaphragm valve seat disposed between the fluid inlet and the fluid outlet; a diaphragm assembly including a diaphragm and a disc, the diaphragm having a primary opening and a bypass opening, the primary opening receiving the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway established by a presence of the diaphragm assembly in the fluid passageway, wherein the diaphragm assembly is disposed in the fluid passageway and is movable between an opened position in which the disc of the diaphragm assembly is not in contact with the diaphragm valve seat and a closed position in which the disc of the diaphragm assembly is in contact with the diaphragm valve seat; and a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet, the relief valve comprising a stationary relief valve housing and an axially-translatable valve element, the stationary relief valve housing having a relief passageway and the axially-translatable valve element having an axial end positionable to selectively seal an upper opening in the relief passageway of the relief valve housing to regulate fluid flow therethrough; wherein, in the closed position of the diaphragm assembly and with the relief valve closed, the disc contacts the diaphragm valve seat to form a seal therebetween and wherein, when the flush valve is activated and the relief valve is opened by lifting the axial end of the axially-translatable valve element from the upper opening of the relief passageway, a flow of water from the chamber into the fluid outlet via the relief passageway occurs thereby relieving a fluid pressure in the chamber and causing the diaphragm assembly to move from the closed position to the opened position such that the disc is unseated from the diaphragm valve seat further permitting water to pass from the fluid inlet to the fluid outlet in a space between the disc and the diaphragm valve seat.
