摘要： A fuel injection apparatus for supplying fuel to an injection valve from a high pressure line includes a control valve controlling pressure in a control chamber connected to the line and an actuator for moving a valve member to actuate via a hydraulic coupler having two pistons acting on a coupler volume, the seat of the valve member having an cross-sectional area f3 for filling the coupler volume with pressurized fuel via guidance gaps of the pistons. The pistons are guided one inside the other and a booster chamber at the ends of the pistons is oriented toward the actuator. A filling chamber inside the outer piston is connected to the line and one piston having a cross-sectional area f4 is mechanically coupled to the actuator by a rod with a cross-sectional area f5; the other piston has a piston area f2, and actuates the control valve via a second rod having a cross-sectional area f1 smaller than f2. The direction of the opening movement of the valve member coincides with the direction of fuel flowing out of the control chamber so that the control valve is at least partially force-balanced due to the pressure acting on the additional piston in the booster chamber.

摘要： A fuel injection valve with a valve body that contains a bore delimited at its end oriented toward the combustion chamber by a valve seat and whose end region oriented toward the combustion chamber has at least one injection opening. A piston-shaped valve needle is contained in the bore in a longitudinally sliding fashion and has an essentially conical valve sealing surface by means of which the valve needle cooperates with the valve seat in order to control the at least one injection opening. The valve seat has a first conical partial surface and a second conical partial surface wherein the second conical partial surface is disposed downstream of the first conical partial surface and is raised in relation to it.
