ABSTRACT:
A solenoid valve for a starting fluid injection system includes a passageway that interconnects the canister valve of the canister with a conduit that transmits starting fluid to the engine. An armature is mounted to slide in the passageway between an open and a closed position. Two valve seats are provided on opposite sides of the armature. The first valve seat is near the exit port of the passageway and is closed by the armature when the solenoid coil is not energized. The second valve seat is an annular O-ring gland designed to receive an O-ring that seals against the exterior of the canister around the threaded neck. When the coil is energized, the armature is moved to the open position, in which both the first valve and the canister valve are opened. A filter and an orifice-defining element are mounted in the valve body between the first valve seat and the exit port. The valve can operate with a coil current as low as 1 amp at 12 VDC.
