摘要： A seal (10) for a piezo-actuator of a fuel injector with terminal posts (12) projecting out of the piezo-actuator and a head arrangement (14) mounted on the piezo-actuator with openings (16) for passage of the terminal posts (12) is particularly suitable even for comparatively thin head plates. A sealing unit (18) mounted on the head arrangement (14) and provided with openings for passage of the terminal posts (12) is provided, having a support (22), on which a sealing material (26) is arranged, which is in contact in a sealing manner with the peripheral surfaces of the terminal posts (12) and a peripheral region of the head arrangement (14) and in which an element (20) made of microporous material is integrated to create gas permeability.

摘要： The invention relates to an injection valve, comprising a control chamber (15) with a control piston (16) that is functionally linked with a nozzle needle (35). The control chamber (15) is linked, via an inlet throttle (13), with pressurized fuel, and with an outlet throttle (14) with a valve chamber (9). A servo valve (5) is disposed in the valve chamber (9), said servo valve opening a connection between the valve chamber (9) and a return element (40) depending on its position. The inventive injection valve further comprises a bypass throttle (12) that is interposed between the fuel feed line and the valve chamber.

摘要： The fuel injector has a housing that is formed from at least one nozzle tension nut, a first injector module and a second injector module. The first injector module and the second injector module adjoin one another and are disposed in the nozzle tension nut. A fuel high-pressure bore is led through the first injector module and the second injector module. A fuel return bore is disposed in the housing. Contact surfaces between the injector modules form a first gap that adjoins the high-pressure bore. Contact surfaces between the nozzle tension nut and the injector modules form a second gap that is connected to the first gap. The return line adjoins the second gap for the discharge of fuel that has entered the second gap from the high-pressure bore via the first gap. The fuel injector is such that the second gap is sealed off relative to the surroundings of the fuel injector.
