    摘要： The electromagnetically actuatable valve includes a valve seat support and a valve needle, both of which are of elongated configuration As a result, the spray discharge point of the valve is advantageously set far forward, which makes possible highly targeted spray discharge. A joining part joining the armature and the valve closure element is configured as a punched and bent part, and has over the majority of its axial extension an open profile differing from a circular cross section. The valve needle thus possesses a mass which is lower as compared with conventional valve needles of identical overall size. The valve is particularly suitable for use in a fuel injection system of a mixture-compressing, spark-ignited internal combustion engine.

    摘要： A fuel injector has a piezoelectric or magnetostrictive actuator, which actuates a valve-closure member cooperating with a valve-seat surface a sealing seat. An hydraulic coupler includes a master piston, a slave piston, and a coupler volume formed in-between, the coupler volume being connected to a compensating chamber via a throttle. An elastic flexible section delimits the compensating chamber at least partially, and the coupler volume, the throttle, and the compensating chamber are filled with an hydraulic medium. The flexible section exerts a pressure on the hydraulic medium due to prestressing, and the force of a compression spring, which is braced either directly and/or via fixed components on the slave piston and the master piston, is directed with an initial stress in such a way that the force enlarges the coupler volume.

    摘要： A fuel injector for fuel injection systems of internal combustion engines has a solenoid operable via an electric wire, a valve sleeve in an injection-side area forming an external sheathing of the fuel injector, and a valve housing. The fuel injector has a plastic sleeve, which contains the solenoid and the electric wire and can be pushed onto the valve sleeve.

    摘要： A method of manufacturing a plurality of piezoelectric actuators (1) includes the following operations: manufacturing of sheets (10) from a piezoelectric ceramic material, coating at least one surface of the sheets (10) with electrodes (3), stacking and pressing the sheets (10) to form a stack, sintering the stacked sheets (10), and separating the stack to form individual actuators (1). At least one cutout (11) for each actuator (1) is made in the sheets (10) prior to stacking and sintering, the cutouts (11) of the sheets (10) being arranged exactly flush one above the other in stacking.

    摘要： A fuel injector, in particular a fuel injector for fuel systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve needle operated by the actuator by way of a hydraulic temperature compensation device, and a valve closing body operated by the valve needle and cooperating with a valve seat face to form a scaling seat. The temperature compensation device includes a needle driving sleeve which surrounds a valve needle shoulder of the valve needle and, together with a needle driving shoulder, surrounds the valve needle in sections. In addition, the needle driving sleeve together with the valve needle encloses a temperature compensation space, and the temperature compensation space is connected to a fuel inlet of the fuel injector through a directional valve for filling the temperature compensation space with fuel.

    摘要： A fuel injector for a fuel injection system of an internal combustion engine includes an energizable actuator having a valve closure element actuable by the actuator by a valve needle, which coacts with a valve seating surface to form a sealing fit and which is held in the closed position by a return spring. The actuator acts on the valve needle via a sleeve-shaped needle driver that is separate from the valve needle, which is arranged in an axially movable fashion with respect to the needle driver, and a collar of the needle driver is engageable behind a needle collar of the valve needle at the end facing away from the return spring.

    摘要： A fuel injector, in particular an injection valve for fuel injection systems of internal combustion engines, has a piezoelectric actuator or magnetostrictive actuator sealed against a fuel by an actuator seal and it has a valve closing body actuatable by the actuator and working together with a valve seat face to form a tight seat. The actuator seal includes a sealing element on the inlet end and a sealing element on the injection end, both designed to be elastically deformable and frictionally engaged with an actuating sleeve. The actuator acts on valve closing body by way of the actuating sleeve, thus at least partially compensating the forces generated by the fuel pressure and acting on the actuator by way of the actuating sleeve.
