摘要： A fuel injection system having an injection valve, a line supplying fuel at high pressure to the injection valve a control valve controlling the pressure in a control chamber communicating with the line. The control valve has a movable valve part is actuatable by an actuator via a hydraulic coupler having two pistons cooperating with a coupler volume of the coupler. A seat of the movable valve part has an inside cross-sectional area f3, with means for filling the coupler volume via guide gaps of the pistons with fuel under pressure. The pistons are located parallel to and inside one another and a booster chamber is located on the ends of the pistons toward the actuator. In the interior of the outer piston defines a filling chamber which communicates with the line and one of the pistons has a cross-sectional area f4 is mechanically coupled to the actuator via a rod having a cross-sectional area f5. The other piston which has a piston area f2, actuates the control valve via a rod having a cross-sectional area that is smaller than f2 and the direction of the closing motion of the movable valve part matches the direction of fuel flowing out of the control chamber so that the control valve is at least partially force-balanced because of the pressure acting on the further piston in the booster chamber.

摘要： A fuel injection device has an injection valve, a line that supplies highly pressurized fuel to the injection valve during operation, a control valve that controls the pressure in a control chamber of the injection valve, which chamber is connected to the line, and whose moving valve element is actuatable by an actuator via a hydraulic coupler having two pistons cooperating with a coupler volume of the coupler, the seat of the moving valve element having an inner cross-sectional surface area f3, and a conduit for filling the coupler volume with pressurized fuel via guidance gaps of the pistons. The pistons are situated one inside the other in parallel fashion; a booster chamber is situated at the ends of the pistons oriented away from the actuator; inside the outer piston, there is a filling chamber that is connected to the above-mentioned line; one of the pistons, which has a piston surface area f4, is mechanically coupled to the actuator by means of a rod that has a cross-sectional surface area f5; the other piston, which has a piston area f2, actuates the control valve by means of a rod that has a cross-sectional area f1 that is smaller than f2; the direction of the closing movement of the moving valve element 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 other piston in the filling chamber.

A piston element is adjustable by a control element and opens and closes a first passage between the inflow line and the pressure chamber. The piston element has a slide element, which is disposed directly at the seat of the piston element. The stroke length of the slide element for opening the first passage is greater than or equal to the stroke length for closing a second passage between the pressure chamber and the leak fuel line.
