Abstract:
An electromagnetic valve for a gaseous fluid comprising a combination of:an electromagnetic circuit which when activated generates an electromagnetic force for mechanical opening or closing of the valve; a movable disk formed member at least part of which is included in said electromagnetic circuit and said disk formed member is guided in a linear movement perpendicular to a surface of said disk formed member; a valve seat cooperating with the disk formed member providing the mechanical closing and sealing of the valve; a resilient member which acts on the disk formed member; and a metering member in the form of a restriction arranged immediately downstream of the valve seat creating sonic conditions for the gas flow which makes the gas flow with the valve open independent of fluctuations in the downstream pressure; said movable disk formed member has a circular form and is provided with a concentric cylindrical guiding member or shaft fixed to and arranged perpendicularly to an upper surface of the disk formed member arranged in an appropriate slide bearing at a center of a fixed armature of the electromagnetic circuit for guiding the movement of said disk formed member in a direction perpendicular to the surface of the disk.
