Abstract: In order to achieve high opening speeds in a dry running gas valve with electromagnetic actuation, it is provided to arrange the engagement point of the magnet armature 22 and the limit stop at the radially inner guide region 16 of the valve element 2. Due to the resulting reduced deflection, the valve element can be built more compact and lighter and the residual air gap can be reduced, which allows higher opening speeds.

Abstract: Large opening cross-sections, long switching strokes and short switching periods are of significance in gas valves for feeding gaseous fuel into the combustion chamber of a reciprocating internal combustion engine and to enable injection of the required quantity of gas into the combustion chamber within the very short available time. An additional means is provided to at least temporarily create additional forces biasing the closing member independent from the forces acting upon the closing member whereby the existing force relationship between the closing spring and the opening solenoid can be especially influenced.
