ABSTRACT:
An injector is described which comprises a valve element engageable with a seating, the valve element being resiliently biased into engagement with the seating. The valve element includes a thrust surface arranged, in use, to have high pressure fuel applied thereto to lift the valve element from the seating. A stop in the form of a second valve member is arranged to restrict movement of the valve element away from the seating, the second valve member being arranged to have high pressure fluid applied thereto and being movable under the influence of the valve element against the action of the high pressure fluid, in use.
