Abstract
A solenoid valve comprising an electromagnetic coil (6) wound on the hub of a bobbin (5) of a plastic material, a metallic central core (10) disposed in the hub (7) of the bobbin, the core forming an axial conduit, and an armature (15) which can be displaced by electromagnetic forces axially towards an end of the said axial conduit in order to control the flow of gas in the said conduit. To this end a thread (11) is formed on the outer surface of the core to cooperate with the inner surface of the hub for the purpose of adjustment of the axial position of the core with respect to the armature.
