Abstract: An electromagnetic valve for a gaseous fluid includes a combination of an electromagnetic circuit which when activated generates an electromagnetic force for mechanical opening or closing of the valve and a movable disk formed member at least part of which is included in the electromagnetic circuit. The disk formed member is guided in a linear movement perpendicular to the surface of the disk formed member. The valve further includes a valve seat cooperating with the disk formed member providing the mechanical closing and sealing of the valve. A resilient member acts on the disk formed member and a metering device in the form of a restriction arranged immediately downstream of the valve seat creates sonic conditions for the gas flow which makes the gas flow with the valve open independent of fluctuations in the downstream pressure.
