Abstract

Abstract A filler valve assembly for a toilet reservoir including a valve mounting fixture mounted in a lower portion of the reservoir and an upright pipe mounted on the valve mounting fixture. A valve member including an elongated stem slidably mounted at an upper end of the upright pipe. The valve member engages a valve seat at the upper end of the upright pipe. A plunger overlies the head of the valve member and is engageable therewith. A float operated arm engages the plunger to depress the plunger and close the valve member when a float carried by the float operated arm is raised. The valve member is released to permit upward flow of water through the upright pipe to be discharged over the upper end of the upright pipe when the float is in a lowered position. The valve closes when there is a negative pressure in the upright pipe to prevent downward flow of water in the upright pipe. A ball valve at the lower end of the upright pipe also prevents back flow. The upright pipe discharges through into a pressure chamber which is connected to a line which discharges through a vacuum breaking air gap.
