摘要： A fuel injection device for an internal combustion engine, having two valve elements each having a hydraulic control surface acting in the closing direction and associated with a hydraulic control chamber. A control valve influences the pressure in the control chamber, and loading devices act on the valve elements in the opening direction. The valve elements react at different hydraulic opening pressures prevailing in the control chamber. The control valve is able to set at least three different pressure levels in the control chamber: all of the valve elements are closed at a comparatively high pressure level; one valve element is open at a medium pressure level; and all of the valve elements are open at a comparatively low pressure level.

摘要： The invention relates to an area of intersection between a high-pressure chamber and a high-pressure duct. To increase the strength in the area of intersection, it is possible to round the area of intersection. The area of intersection includes at least one planar area or an area that is curved markedly less than the remaining area of intersection. The planar area may also be embodied as only nearly planar. The high-pressure chamber and the high-pressure duct are also called functional chambers. By means of the planar or nearly planar area, an intersection geometry is created, in which tensile stresses of the functional chambers that occur upon subjection to pressure are not superimposed directly and add up as they do in conventional intersection geometries. By means of the planar area in the area of intersection, it is attained that in the intersection geometry of the invention, under pressure, local pressure stresses or markedly reduced tensile stresses occur in an inner wall of the high-pressure chamber and are then superimposed with the tensile stresses in an inner wall of the high-pressure duct. Since with the intersection geometry of the invention, a tensile stress has only a reduced tensile stress or in the best case a pressure stress superimposed on it, the total is less and hence the maximum stress that occurs is reduced markedly.

摘要： The invention relates to a fuel injector with an injector housing (6) comprising a pressure chamber (15), from which, depending on the pressure in a control chamber (22), pressurized fuel is injected into a combustion chamber of an internal combustion engine when the pressure in the control chamber (22) with the aid of a control valve device (12) is reduced so far, that a nozzle needle (10) opens.

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 injection system for an internal combustion engine including a fuel injector which can be subjected to fuel at high pressure and is actuatable via a metering valve device by which the pressure in a pressure booster control chamber is controllable such that the pressure in a pressure booster pressure chamber, defined by a pressure booster piston, that can be filled with fuel from the high-pressure fuel source via a filling path in which a check valve is disposed and that is in communication with an injection valve member pressure chamber, is increased by the pressure booster piston such that an injection valve member opens for injecting fuel, whereupon fuel is positively displaced out of a damping chamber via a damping path, in which a damping throttle is disposed. To assure stable injection performance, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from the damping chamber via the damping throttle in an injection event reaches the filling path of the pressure booster pressure chamber via the damping path.
