Sensor-operated battery-powered flush valve

A sensor-operated battery powered flush valve for a toilet device including a valve body having a water inlet and a water outlet, valve means within the valve body for controlling water flow between said inlet and said outlet including a diaphragm movable toward and away from a valve seat in said valve body, a mounting member in said valve body, a chamber between said mounting member and diaphragm, water pressure in said chamber maintaining said diaphragm closed upon said valve seat, a water passage within said mounting member connecting said chamber and said outlet,

• a latching solenoid mounted on said mounting member and including a solenoid plunger, said solenoid plunger moving along an axis perpendicular to the axis of movement of said diaphragm to control the flow of water through said passage and thus the operation of said valve means, battery means mounted in said valve body on the opposite side of said mounting member from said diaphragm for connection to said solenoid to provide the electric power for operation thereof, sensing means positioned within the valve body, on the opposite side of said mounting member from said diaphragm for sensing the presence of a user of a toilet device, said sensing means functioning to connect the battery means to the solenoid to cause activation thereof to cause said solenoid plunger to move to permit water flow through said passage to permit movement of said diaphragm away from said valve seat to connect said inlet and said outlet, and
• means within said valve body for connecting said battery means to said solenoid to cause activation thereof to cause said solenoid plunger to close said passage whereby said diaphragm closes upon said valve seat to stop water flow between said inlet and outlet.
