    摘要： A fuel injector (10) for a compression ignition internal combustion engine is described. The fuel injector (10) comprises a fuel injection valve having an injection valve member (14) moveable, in use, under the influence of fuel pressure within a control chamber (20) acting upon it, between a closed position and an open position. The fuel injector comprises a moveable plate (28) located inside the control chamber (20). The moveable plate (28) is configured to move into and out of contact with a sealing surface (34) of the control chamber (20). The moveable plate (28) includes an inlet orifice (38) and a spill orifice (40). The provision of inlet and spill orifices (38, 40) in the moveable plate allows both orifices to be made very small, resulting in a significant reduction in dynamic leakage. An embodiment of the invention is described in which the moveable plate (28) defines additional fluid channels (60a, 60b, 62a, 62) for high pressure fuel entering the control chamber (20) when the moveable plate (28) is moved out of sealing contact with the sealing surface (34) of the control chamber (20). The additional flow paths allow high pressure fuel to enter the control chamber (20) bypassing the inlet orifice, resulting in a rapid termination of an injection event.

    摘要： A fuel injection system for an internal combustion system comprises an Engine Management System (EMS) (6), a fuel feed pump (2), a return line (13), a high-pressure pump (3), supplying fuel under pressure to a common rail (4), a hydraulically operated valve (7) forming an outlet chamber 9 connected to the common rail (4) and a control chamber 10, the valve (7) being designed such that, in its closed position, the valve prevents the flow out of the outlet chamber (9), and an electrically operated pilot valve (12). A nozzle (8) with a resilient means 18 that biases the nozzle towards closing, is connected to the outlet of the hydraulically operated valve (7) in such a way that pressure at the outlet of the hydraulically operated valve (7) tends to overcome the force of the resilient means (18) and open the nozzle (8). An electrically operated spill valve (19) is connected between the outlet of the hydraulically operated valve (7) and the return line (13).

    摘要： Disclosed is an electromagnetically controlled connecting unit for controlling the passage of a fluid-conducting junction between the high-pressure system and the low-pressure system of a cam-actuated injection system in a self-igniting internal combustion engine. Said electromagnetically controlled connecting unit comprises: - a driving slide (1) that is guided in a precisely fitting manner within an axial guiding bore (32) of a slide cylinder (3), which is fluidically connected to the high-pressure system (37); - an overflow chamber (39) that is fluidically connected to the guiding bore (32) via an electrically controlled magnetic valve (9, 10, 2) while being fluidically connected to the low-pressure system (38) via an overflow chamber bore (50); - a transversal bore (42) that crosses the guiding bore (32) and is connected to the high-pressure system (37) at one end and to the low-pressure system (38) at the other; - a block control bore (17) which extends into the guiding bore (32) downstream of the transversal bore (42) in the direction of displacement of the driving slide counter to the restoring force of the slide spring (12), said block control bore (17) being fluidically connected to the low-pressure system (38).
