Abstract
Two or more poppet valves are mechanically coupled or linked to each other by a web. A single valve stem operates the multiple poppets together. One poppet controls the flow of a liquid from a reservoir. The other poppet controls the flow of air into the reservoir. The air control poppet opens after the liquid control poppet enabling a vacuum to be developed in the reservoir before the air control poppet opens. Air is thus drawn into the reservoir through the air control poppet.
