Abstract: A gas metering valve (1) having at least one valve seat (2) and at least one closure member (3) which can be pressed against the valve seat, the closure member in a maximum open position is raised at least in regions from the valve seat (2) and in a maximum closed position is pressed against the valve seat. The gas metering valve (1) has an adjusting device (5) which is spring-loaded by a spring loading device (4) of the gas metering valve (1) for adjusting the closure member (3) in a closing direction (6) from the maximum open position into the maximum closed position. The spring loading device (4) of the adjusting device (5), preferably when viewed in the closing direction (6), has at least two spring bodies (7a, 7b) which are connected mechanically in series, the spring bodies (7a, 7b) have elastic characteristics which are different from each other.

Abstract: A gas metering valve has a valve seat and a closure member which can be pressed against the valve seat in a closed position, and a tiltable lever for pressing the closure member against the valve seat. A transmission plate is arranged between the closure member and the lever in such a way that the lever, or a transmission element arranged at the lever, slides along the transmission plate during a tilting movement of the lever so that the closure member is movable from an open position into its closed position.
