    摘要： Bei einer Kraftstoffeinspritzvorrichtung mit einer bei vorbe­stimmtem Druck öffnenden Einspritzdüse (3), welcher Kraft­stoff unter Druck zuführbar ist, ist der Einspritzdüsenraum (2) mit einer Kraftstoffzuleitung (8) unter Zwischenschaltung eines nach außen schließenden Rückschlagventiles (9) verbun­den, wobei der Druck in der Kraftstoffzuleitung (8) geringer ist als der Öffnungsdruck der Einspritzdüse. Weiters ist der Einspritzdüsenraum (2) mit einem Arbeitsraum (14) eines federbelasteten Arbeitskolbens (12) verbunden, dessen Ver­schiebebewegung zur Druckerhöhung des Druckes im Düsenraum (2) über den Öffnungsdruck der Einspritzdüse (1) durch Entlastung eines gesonderten Arbeitsraumes (20) des feder­belasteten Arbeitskolbens (12) unter Einwirkung der Feder­kraft erfolgt.

    摘要： The invention concerns a system for the supply of fuel-injection, internal combustion engines, comprising a pump unit and an injector unit which are part of an integrated assembly. In the pump unit, an intake and supply piston (15) forms a movable anchor, displaced by an electromagnet (13) which exercises its force of attraction against a contrast spring (12). The operation of the electromagnet (13) acts on the piston in the intake direction, while the supply stroke of the piston (15) is driven by the sole elastic energy stored in said spring (12). The instant starting fuel injection coincides with the opening instant of the needle (28) of the injector (27).

    摘要： A fuel pump having a rotary drive shaft (24), a high pressure pump (70) and a transfer pump (150). The high pressure pump has one or more reciprocating pumping plungers (14) and a pumping plunger actuator (62, 48, 66) driven by the drive shaft for reciprocating each pumping plunger to provide alternating intake and pumping phases of operation of the high pressure pump, at a frequency determined by the rotational speed of the drive shaft, for respectively receiving an intake charge of fuel and delivering fuel at high pressure for fuel injection. The fuel transfer pump has a reciprocating transfer plunger (152) reciprocated to provide alternating intake and transfer phases of operation of the transfer pump for respectively receiving fuel and transferring fuel under pressure to the high pressure pump. The transfer pump comprises a transfer plunger actuator (176, 182, 60) driven by the drive shaft to reciprocate the transfer plunger at the same frequency as the high pressure pump and in predetermined synchronism with the high pressure pump to transfer fuel intermittently to the high pressure pump during the intake phase of operation of the high pressure pump and the transfer phase of operation of the transfer pump.

    摘要： A fuel injection system (100) for an internal combustion engine is disclosed. The fuel injection system comprises at least one electronically-controlled fuel injector (102), a fuel pump (104) for supplying pressurised fuel to the or each injector (102), and a controller (130) arranged to control the injection of fuel from the or each injector (102). The fuel pump (104) comprises a pump chamber (146), a pumping element (140), and a drive mechanism (360) for driving the pumping element (140) in a pumping stroke in which the volume of the pump chamber (146) is reduced, and a filling stroke in which the volume of the pump chamber (146) is increased and in which fuel is admitted to the pump chamber (146) from a fuel source (116). The drive mechanism (360) comprises a biasing arrangement (468) arranged to apply a resilient biasing force, such as a spring force, to the pumping element (140) to drive the pumping stroke. In this way, the resilient biasing force acts to pressurise the fuel for injection, providing a simplified fuel injection system with electronic control of the injection timing and duration. Fuel pumps suitable for use in such a system are also disclosed.
