Abstract:
An injector comprising:a common cylinder comprising a first non-magnetic portion and first and second magnetic portions disposed on opposite sides of the first non-magnetic portion, the first non-magnetic portion and the first and second magnetic portions forming an integral, leak proof cylinder, wherein a substantially hollow fuel passage is defined within an interior of the common cylinder, an armature slidably disposed within the fuel passage of the common cylinder, the armature having a forward edge, a rearward edge and a substantially hollow fuel passage provided within an interior of the armature, the armature being adapted to move in response to magnetic fields, a first solenoid coil coaxially disposed about the common cylinder adjacent to the forward edge of the armature, a second solenoid coil coaxially disposed about the common cylinder adjacent to the rearward edge of the armature, wherein a space exists between the first solenoid coil and the second solenoid coil and said space is adjacent to the first non-magnetic portion of the common cylinder and a value coupled to the armature, wherein the valve closed in response to a magnetic field generated by the first solenoid coil and the valve opens in response to a magnetic field generated by the second solenoid coil.
