摘要： A governor system for the fuel pump of an engine which drives a vehicle through a multi ratio gearbox includes an all speed governor. The governor characteristic in the intermediate speed range is modified by means responsive to the load on the vehicle and by means responsive to the transmission ratio of the gearbox.

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 linear transducer comprises a former about which is wound a number of windings, the windings being disposed in side by side relationship and having the same number of turns. The windings are connected in series with adjacent windings being wound in the opposite direction. The transducer also includes a core member which has a length substantially equal to the length of the winding. The inductance of the windings varies cylically as the core member is moved through the former.

摘要： An electromagnetically operable valve for controlling the escape of fuel from the pumping chamber of a high pressure pump includes a valve member slidable in a bore from the end of which extends an outlet about which is formed a conical seating. The valve member is shaped to cooperate with the seating and is urged into contact with the seating when an electromagnetic device is energized. A fuel inlet passage connected to the pumping chamber extends into a chamber defined by a reduced portion of the valve member and the portion thereof which slides in the bore forming a step which defines an annular surface which is exposed to the pressure in said chamber. When the device is deenergized the fuel pressure acting on said surface acts to move the valve member to the open position.

摘要： A fuel pumping apparatus of the rotary distributor type has a pumping plunger (14) mounted in a bore (13) in the distributor member and a cam ring (24) operable to move the plunger inwardly in timed relationship with the associated engine. The cam ring is positioned by a fluid pressure operable piston (25) contained within a cylinder (26). The apparatus includes a further piston (31) mounted in a further cylinder connected to the first mentioned cylinder, the further piston being biased by a pre-stressed spring (32). A stop is provided to limit the movement of the further piston against the action of the spring which yields to limit the fuel pressure developed by the plunger during the initial inward movement.

摘要： A fuel injection pump includes a plunger reciprocable by an engine driven cam in a bore from which extends an outlet connected in use to a fuel injection nozzle. A spill valve is utilized to control the fuel flow to the nozzle by diverting fuel from the outlet to a low pressure source. In order to prolong the valve closure period a cylinder is provided in which is located a spring loaded piston. When the valve is closed a predetermined volume of fuel is passed to the cylinder to achieve displacement of the piston after which delivery of fuel takes place through the nozzle. The period of closure of the valve in order to achieve delivery of a specific volume of fuel through the nozzle is therefore extended.
