Abstract
A flush valve assembly includes a resilient pinch tube disposed in a conduit between a pressurized water source and a toilet flush tank and is pinched closed by a piston disposed in a cylinder formed in a bracket mounted on the conduit. The piston is engageable by a float which moves it between closed and open positions with changes in water level. A tube connects the source to the cylinder. When the float moves to the closing position it closes a drain port in the cylinder so that water pressure in the cylinder assists the piston. A manually adjustable screw on the float cammingly engages a bead on the conduit to yieldably arrest upward float movement and provide snap-action shutoff of the valve.
