Abstract
A self-closing valve, having means to discharge a predetermined volume of water for each cycle of operation, is disclosed. The valve includes the arrangement of timing means which determines the elapsed time for its operational cycle, a one-way valve means to expel air from the metering chamber during the actuating cycle of the valve, and air metering means which replaces air entering the mixing chamber at a constant uniform rate, all of which cooperate with the valving means to discharge a predetermined volume of water.
