Abstract
An actuating valve serves as a pilot to a control valve for a valve controlled flushing system for a tank-type toilet installation which comprises a siphon flush valve, and a control valve that allows supply water to flow into the tank to initiate siphonic action, to supplement flow through the siphon flush valve and to refill the tank, which control valve utilizes a piston which is ordinarily seated in a closed position by supply line pressure. The actuating valve is located in a bypass passage between the supply pressure and a timing pressure chamber of a control valve. The actuating valve comprises a triggering mechanism, a valve housing, an internal passageway through the valve housing for the flow of supply water and the transfer of supply line pressure, valve means positioned in said housing which upon activation of the triggering mechanism interrupts the flow of supply water and the transfer of supply line pressure through the passageway until the pressure on the piston of the control valve is relieved, the timing pressure chamber is emptied, and the control valve is opened to initiate a flushing cycle and means for disengaging the triggering mechanism to prevent premature o…
