Abstract: A fuel pumping apparatus includes a plunger which passes centrally through an annular member and is movable axially relative to the member. The plunger is connected to the member so that angular movement of the member will impart angular movement to the plunger by means of a dog which passes within a slot formed in the member. The plunger is loaded outwardly by means of a strong spring and during assembly of the device it is necessary to compress the spring and align the dog with the slot continuing the compression of the spring when such alignment is obtained. This task is not easy but is facilitated by relieving one end surface of the member adjacent one side of the slot over an area such that alignment of the dog with the surface is compartively easy. During compression of the spring and movement of the plunger the dog will engage with said surface. When this has happened the pressure is eased slightly and the member moved angularly so that a side surface of the dog engages the side surface of the slot opposite the relieved portion of the member. Further compression of the spring can then take place.

Abstract: A fuel system for use with viscous fuels comprising a housing defining a supply passage through which fuel can flow, in use, from a source of viscous fuel towards a fuel pump, and a throttle member located within the housing and arranged to control the rate of fuel flow along the supply passage. The throttle member is angularly adjustable within the housing to adjust the permitted fuel flow rate between the source and the pump.

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.
