Abstract

A gas metering valve for an internal combustion engine. The gas metering valve includes a housing in which a gas chamber is formed, which includes an inlet opening and an outlet opening. A movable valve element is situated in the gas chamber, which is movable by an electrical actuator against the force of a return spring and which cooperates with a valve seat for opening and closing the inlet opening. A blocking valve is situated between the valve element and the outlet opening, which opens in the flow direction to the outlet opening and blocks in the opposite flow direction.
