摘要： A needle type fuel injector has a needle control chamber at a pressure subject to a control valve in a control valve chamber which in an opening phase is lifted from its seat to expose the control valve chamber, connecting passage, and needle control chamber to a low pressure drain and in a closing phase is urged against the seat to isolate the control valve chamber, connecting passage, and needle control chamber from the drain. The potential for cavitation at high fuel injection pressure is reduced by throttling the flow of fuel past the control valve seat when the control valve opens, thereby maintaining sufficient back pressure in the control valve chamber and upstream connecting passages.

摘要： A fuel injection system for an internal combustion engine includes an engine management system, a return conduit connected to a low-pressure fuel system, and a common rail for storing and supplying a relatively high-pressure fuel to injectors. Each injector has a nozzle for injecting fuel into the engine, a valve installed between the common rail and the nozzle, and a spill valve connected by its inlet to the outlet of the valve and by its outlet to the return conduit. A first automatic isolating valve is installed between the common rail and the injector and a second automatic isolating valve is installed between the return conduit and the low-pressure fuel system.

摘要： A common rail single fluid fuel injection system includes fuel injectors with a single electrical actuator but the ability to produce ramp, square and split injection rate shapes. This is accomplished by including a control valve member that is operably coupled to the electrical actuator and is movable between a high pressure seat and a low pressure seat. A fuel supply passage is opened to a nozzle passage by moving an admission valve member from a closed position to an open position by relieving fuel pressure on a control surface via movement of the control valve member. In addition, a needle valve member is movable from a closed position to an open position by relieving pressure on a closing hydraulic surface associated with the needle valve, which is again accomplished via movement of the control valve member via the electrical actuator.

摘要： The invention relates to a fuel injection device with a multi-part injector body containing a pressure booster that can be actuated by means of a differential pressure chamber, and includes a pressure booster piston that seals a working chamber off from the differential pressure chamber. An on-off valve, disposed above the injector body can actuate the fuel injection device. A pressure change in the differential pressure chamber occurs via a central control line that extends through the pressure booster piston of the pressure booster.

摘要： A fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, having a pressure booster in which the piston divides a work chamber, acted upon permanently by fuel via a pressure source, from a pressure-relievable differential pressure chamber. A pressure change in the differential pressure chamber is effected via an actuation of a servo valve. The control chamber of the servo valve can be pressure-relieved via a relief valve and which opens or closes a hydraulic connection of the differential pressure chamber with a return. For closing the servo valve piston, the control chamber can be acted upon by a fuel volume diverted from the differential pressure chamber. The action of fuel on the control chamber is effected via lines that contain throttle restrictions. A pressure relief of the control chamber is effected via a relief valve into a return on the low-pressure side.
