A gas valve with electromagnetic actuation, in particular for use as a fuel injection valve for gas engines, includes a sealing element (,), actuable by way of an armature (,) of a controllable electromagnet (,), between a or each fuel inlet (,) and a or each fuel outlet (,), and at least one closing spring (,) acting on the sealing element (,). In order to achieve very short switching and response times while at the same time having a large passage cross-section, and thus to render the gas valve suitable also for use in multi-point systems and in supercharged engines, in particular gas engines for commercial vehicles, the gas valve is designed as a flat-seat valve with a plane valve seat (,) and a sealing element (,) with at least one plane sealing surface facing this valve seat.

Gas valve with electromagnetic actuation

A gas valve with electromagnetic actuation, in particular for use as a fuel injection valve for gas engines, is provided with a sealing element (7), actuable by way of an armature (12) of a controllable electromagnet (19), between a or each fuel inlet (4) and a or each fuel outlet (24), and at least one closing spring (8) acting on the sealing element (7). In order to obtain an opening cross-section which can be simply and rapidly calibrated and adjusted in a certain range, an element (1, 2, 18) is present for adjusting the distance between the electromagnet (19) and the armature (12).
