A solenoid valve (10) for a starting fluid injection system includes a passageway (32) that interconnects the canister valve (20) of the canister (18) with a outlet (52) that transmits starting fluid to the engine. A first valve seat (36) is near the exit port (52) of the passageway (32) and is closed by an armature (40) when the solenoid coil (34) is not energized. A second valve seat (38) is an annular O-ring (39) gland that seals against the exterior of the canister (18) around the threaded neck (22). When the coil is energized, the armature (40) is moved to the open position, in which both the first valve seat (36) and the canister valve (20) are opened. A filter (54) and an orifice (60) are mounted in the valve body.
L'invention concerne une électrovanne (10) pour système d'injection de liquide d'allumage, comportant un passage (32) qui relie la soupape (20) du récipient (18) à une sortie (52) qui transmet le liquide d'allumage au moteur. Un premier siège (36) de soupape se situe à proximité de l'orifice de sortie (52) du passage (32) et est fermé au moyen d'un induit (40) lorsque la bobine de solénoïde n'est pas alimentée. Un second siège (38) de soupape est une presse-étoupe à joint torique (39) qui est scellée à la paroi extérieure du récipient (18) autour du col fileté (22). Lorsque la bobine est alimentée en courant, l'induit (40) passe dans la position ouverte dans laquelle, à la fois le premier siège (36) de soupape et la soupape (20) du récipient, sont ouverts. Un filtre (54) et un orifice (60) sont fixés dans le corps de la soupape.
