CA 2151841
A gas injector for a gas fuelled internal combustion engine. The gas injector comprises a valve member adapted to seat against a valve seat in a first or closed position, in which a flow of gas through the injector is prevented, and being movable to a second or open position in which the valve member is lifted from the valve seat to permit a flow of gas through the injector. The injector further comprises a solenoid actuator for moving the valve member from the first to the second position responsive to an electrical control signal. In use, by modulating the electrical control signal a precisely controlled quantity of gas can be delivered by the gas injector to the internal combustion engine. The valve member has a conical valve face and a hollow elongate valve stem having a first opening at one end and a second opening in the form of three radial apertures at the other end to allow a flow of gas through the valve member in use. The valve stem is provided with an annular flange at one end, which faces the end face of the solenoid actuator. The annular flange is of magnetic material and forms the armature of the magnetic circuit formed by the solenoid actuator. Outer casing of the injector is manufactured of magnetic material, and a wall of the outer casing is located immediately adjacent a coil so that, in use, together with a core member and annular flange, it forms part of the magnetic circuit of the injector. Careful design of the mechanical structure and magnetic circuit reduces flux leakage and minimizes the total air gap to provide a rapid response time for the injector.
