    摘要： A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a throttle member having a groove which can register with a port to control the fuel flow to an injection pump forming part of the apparatus. The throttle member is angularly movable by a governor and is also axially movable. The groove has an inclined edge so that the variation in the axial setting will also control the fuel flow. A pivotal lever has one end engaging the throttle member and its other end mounts a cam follower which engages with a cam surface formed on a cam ring which is part of the injection pump and which is angularly movable in accordance with the speed of the engine. As the speed varies so also does the axial setting of the throttle member.

    摘要： An engine system includes a valve operable to permit exhaust gas to flow from the exhaust manifold to the air inlet manifold of an engine for the purpose of reducing the noxious gas content of the exhaust. The setting of the valve is dependent upon the amount of fuel supplied to the engine by the pump. A hydraulic signal is generated and this is derived from a supply pump by way of a fixed orifice this pressure being applied to a control valve which regulates the pressure applied to an actuator including a spring loaded piston. A throttle which controls the amount of fuel delivered by the injection pump also forms a further adjustable orifice downstream of the orifice whereby the pressure downstream of the orifice is dependent upon the amount of fuel supplied to the engine.

    摘要： A fuel pumping apparatus for supplying fuel to an internal combustion engine includes an adjustable throttle movable against the action of resilient means by means responsive to the speed of operation of the associated engine to which fuel is being supplied. Movement of the throttle against the action of the resilient means reduces the rate of fuel supplied to the engine and temperature responsive means is provided to adjust the throttle to increase the rate of fuel supplied to the engine when the engine is cold.

    摘要： A fuel injection pumping apparatus for supplying fuel to an internal combustion engine includes an injection pump comprising a pair of reciprocable plungers located in a bore and moved inwardly in timed relationship by cam lobes formed on an annular cam ring. The bore containing the plungers is connected to a delivery passage whereby fuel is delivered in turn during successive inward movement of the plunger to a plurality of outlet ports. Fuel is supplied to the injection pump by way of valve means from a further pump, also incorporating a pair of reciprocable plungers movable inwardly by means of cam lobes on a cam ring. The displacement of the plungers of the further pumps is greater than that of the plungers of the injection pump and means is provided to alter the stroke of the plungers of the further pump during which fuel is supplied to the injection pump. In one example this is achieved by means of a spill port which is brought into register with the bore containing the plungers of the further pumps and in addition the cam ring of the further pump is angularly adjustable.

    摘要： A distributor type fuel injection pump includes an injection pump to which fuel is supplied from one end of a bore accommodating a slidable shuttle. The shuttle is moved towards the one end of the bore during the filling strokes of the injection pump by way of a first valve means and is allowed to move away from said one end of the bore during an interval between the filling strokes of the injection pump by fuel under pressure derived from the outlet of a feed pump by way of a second valve means. An electrically operable valve is provided to limit the amount of fuel which can flow from said other end of the bore and a sensor is provided to detect the position of the shuttle within the bore and which by way of a control circuit actuates said electrically operable valve. A third valve means is provided to admit fluid under pressure to said other end of the bore when it is required to fill the injection pump.
