Gas metering valve

A gas metering valve, comprising:

• a housing in which a gas chamber is formed, which can be filled with gaseous fuel via an inlet opening and from which gaseous fuel can be discharged in a metered manner via an outlet opening;
• a valve element which is longitudinally moveably arranged in the gas chamber, wherein the valve element has a valve seal surface which cooperates with a valve seat for opening and closing the outlet opening;
• a magnetic armature which is connected to the valve element and can be moved by an electromagnet;
• a bellows which is connected in a gas-tight manner to the valve element at one end and to the housing at the other end, wherein the gas-tight connection with the housing is formed along a sealing line;
• wherein a diameter of the sealing line is greater than a diameter of the valve seat, such that, using pressure in the gas chamber, a resulting pneumatic longitudinal force is exerted on the valve element in a closing direction.
