摘要： A fuel injector with direct triggering of an injection valve member in which an actuator is received in the hollow chamber which is subjected to fuel that is at high pressure via a high-pressure source disposed outside the fuel injector. The actuator is supplied with current in the closing position of the injection valve member and is not supplied with current in the open position of the injection valve member. The actuator acts directly on a booster piston of a pressure booster, which booster piston acts upon the booster chamber. A control chamber sleeve defining a control chamber is movably received in the booster piston.

摘要： The invention relates to an injector for injecting fuel into a combustion chamber of an internal combustion engine. The injector is actuated by an actuator and is connected to a fuel supply line via which fuel is supplied under system pressure. At least one injection opening can be opened or closed off by an injection valve member, which is activated by a control piston via a control chamber to which the control piston and a piston section of the injection valve member are exposed with respective pressure faces. The control piston is a valve piston of a control valve. The pressure face of the control piston and the pressure face of the piston section of the injection valve member are exposed to the control chamber at the same side. The control piston and the piston section of the injection valve member also enclose a further control chamber which is connected to a fuel return line when the control valve is open and to the fuel supply line when the control valve is closed.

摘要： A piezoelectric actuator and an injector for an internal combustion engine are proposed, the electromagnetic compatibility of which is significantly improved in comparison with conventional injectors. The actuator head and/or actuator foot is manufactured out of a ceramic material, thus reducing the capacitance of the electric capacitor that is formed between the electrical ground and the piezoelectric actuator. An advantage of the piezoelectric actuator according to the invention is that no additional components are required. The change from metallic materials to ceramic materials also increases the rigidity of the piezoelectric actuator since ceramic materials have a significantly higher modulus of elasticity than metals.

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 booster chamber of the coupler. A seat of the movable valve part has an inside cross-sectional area f3, with means for filling the booster chamber 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 common rail injector having an injector housing that has a fuel inlet, which communicates with a central high-pressure fuel source outside the injector housing and with a pressure chamber inside the injector housing, from the latter of which, depending on the pressure in a control chamber, highly pressurized fuel is injected into a combustion chamber of an internal combustion engine when a nozzle needle lifts away from its seat, and in which the pressure in the control chamber is directly controlled by a piezoelectric actuator. The end of the nozzle needle oriented away from the combustion chamber accommodates a control chamber delimiting sleeve that can move back and forth and reduce the size of the control chamber-pressurized end surface of the nozzle needle oriented away from the combustion chamber.
