<p>The solenoid valve comprises a winding (1) wound around a carcase (2), an outer magnetic circuit (5), at least one fixed plunger (10, 11) and one movable plunger (17). The movable plunger (17), of flat configuration is produced as a metal washer (19) at the centre of which there is arranged a stopper member (23) made from a flexible non-metallic material, provided to come to bear against at least one fixed seat (15, 16) to give rise to the stopping of at least one fluid passage (12, 14). The metal disc (19) further carries peripheral stubs (24) acting as end-of-travel stops, and it has radial notches traversed by centring, guidance, and retaining fingers (26, 27). <IMAGE></p> |
