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 17):
A method for operating a flush valve, the method comprising the steps of:\n (a) providing a fluid under pressure to a fluid passageway in a valve housing via a fluid inlet; (b) communicating the fluid through a bypass opening in a diaphragm assembly into a chamber, the diaphragm assembly being disposed in the fluid passageway and being movable between an opened position in which the diaphragm assembly is not in contact with a diaphragm valve seat and a closed position in which the diaphragm assembly is in contact with the diaphragm valve seat, wherein the chamber is established by a presence of the diaphragm assembly in the fluid passageway; (c) communicating the fluid in the chamber into a relief valve, 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 stationary relief valve housing to regulate fluid flow therethrough; (d) translating the axially-translatable valve element into an open position such that the upper opening in the relief valve housing is unsealed by the axial end of the axially-translatable valve element; (e) communicating the fluid through the relief valve to a fluid outlet; and (f) translating the diaphragm assembly from the closed position to the open position such that the diaphragm assembly is unseated from the diaphragm valve seat permitting water to pass from the fluid inlet to the fluid outlet in a space between the diaphragm assembly and the diaphragm valve seat.
