摘要： The invention relates to a device for injecting high-pressure fuel into an internal combustion engine. An injector (25) comprises a pressure chamber (1) from which a high pressure line (3) opens into a control chamber (4) of a nozzle needle (5). The injector (25) also contains two control valves (11, 12) which are connected to low-pressure areas (9) on the discharge side. One of the control valves (11, 12) that determine the injection pressure curve (20) contains a pressure compensation system (34), enabling the injection pressure curve (20) to be varied through modification of the stroke path (23) of the nozzle needle (5).

摘要： A fuel pumping apparatus for supplying fuel to an internal combustion engine has a plurality of pumping plungers (19) which are housed in respective bores (17). The plungers are movable inwardly in the bores but during such movement one of the plungers moves to an outer position in which a fuel supply passage (21) which communicates with a fuel supply passage (21) which communicates with a fuel outlet (22) is uncovered to the pump working chamber (20) defined at the inner ends of the bores. Each bore has a supply passage associated therewith. A cam ring (25) is provided to impart inward movement of the plungers and the cam ring is provided with cam lobes (26) on its internal peripheral surface however one of the cam lobes is replaced by a recess which allows the plungers to move outwardly in turn so that fuel is distributed to the outlets which in use are connected to the injection nozzles of an engine.
