Abstract
A flushing apparatus for controlling water flow in a toilet flushing system. The flushing system includes a pressure tank and differential-pressure type flush valve that opens when accumulated fluid pressure above a piston is vented to atmosphere. The apparatus includes an actuator for venting the flush valve which includes a tubular member that defines an air flow passage through the flushing apparatus. The air flow passage is selectively controlled by a blocking member which slides within and relative to the tubular actuator. The air flow passage can be used to ventilate the corresponding toilet bowl when the system is at rest.
