<p>Solenoid (electromagnetic) valve including an electromagnetic coil (6) wound on the hub of a plastic bobbin (former) (5), a central metallic core plunger (10) located within the hub (7) of the bobbin, the said core plunger forming an axial passage, and an armature (15) capable of being moved by the electromagnetic forces axially in the direction of one end of the said axial duct with a view to causing gas to flow through the said duct. For this purpose a screw thread (11) is formed on the external surface of the core plunger in order to interact with the internal surface of the said hub with a view to adjusting the axial position of the core plunger relative to the armature. <IMAGE></p> |
