ABSTRACT:
A metering valve having a metering chamber (7) and a valve rod (2) lying in a valve body (1). The valve rod includes an inlet channel (211, 214) which puts the metering chamber (207) into communication with a can (11) of substance under pressure when the valve rod is in a rest position. The inlet channel forms a siphon which prevents the valve from draining when it is the rightway up.
