US 2012/0222205 A1 · Automatic flush actuation apparatus

Abstract

An automatic flush actuation apparatus, which is incorporated with a flushing system having a water inlet, a water outlet, and a water chamber communicating therebetween, that includes a valve member being moved by a flush lever for releasing the water pressure within the water chamber to allow the water passing from the water inlet to the water outlet, and a sensor-operated powering assembly including a relief valve provided at the valve member for controlling the water flowing to the water outlet and an actuator arranged in such a manner that while sensing a presence of a user of the flushing system, the actuator is driven to move the relief valve to an opened position for releasing the water pressure within the water chamber to allow the water passing to said water outlet.

Claims12

Dependent claims

A powering assembly of an automatic actuation apparatus comprising a relief valve for controlling volume of water used in a flushing cycle of a flushing system which, when executed by a control processor in said automatic actuation apparatus, cause said control processor to perform flushing operations of:

detecting a presence of a user of said flushing system;
activating said control processor to adjustably control a time of said flushing cycle and water volume for said flushing cycle by moving said relief valve from an closed position to an opened position.;
starting said flushing cycle of said flushing system;
and
completing said flushing cycle of said flushing system in responsive to said time of said flushing cycle and said water volume for said flushing cycle.
