    摘要： The invention relates to a support assembly for a piezoelectric actuator (15), in particular for a piezoelectric actuator for driving an injector for the injection system of an internal combustion engine. Said assembly comprises a holder (5-10) for spatially securing a piezoelectric stack (2) and two associated connection pins (11, 12) for electrically contacting said stack (2). According to the invention, the support assembly is configured as a single support, which only holds a single piezoelectric stack (2) with two associated connection pins (11, 12). The invention also relates to an associated production method.

    摘要： A piezo actuator has a stack element and at least one further stack element, wherein each of the stack elements has stacked piezoceramic layers and electrode layers arranged between the piezoceramic layers, each of the electrode layers extends to at least one of at least two lateral surface sections of the stack element which have external metallizations on them, and are connected to the electrode layers such that adjacently stacked electrode layers can have different electrical potentials applied to them indirectly via the external metallizations, the stack elements are arranged above one another to form a monolithic total stack, and connected to one another by at least one connecting layer. The following steps are provided: a) provision of the total stack and b) production of a load-relieving crack in the connecting layer. An electrical connector in the form of a wire can be fitted on the relevant external metallization regions.

    摘要： A servo drive includes a piezoelectric actuator contained in a drive housing. The actuator has an actuator stack surrounded by a hollow cylindrical spring element and an actuator casing disposed in the spring element. The spring element is clamped, together with the actuator stack, between an actuator cap and an actuator base. An elastic compound fills gaps between the drive housing and the spring element as well as between the spring element and the actuator casing, and damps an actuator motion. A piezoelectric actuator for the servo drive and a method of producing the piezoelectric actuator are also provided.

    摘要： A method is described for improving the long-term stability of a piezoelectric actuator encased in a potting compound containing or forming hydrogen atoms. Oxygen is contained in the piezoelectric actuator's piezoelectric ceramic. Appropriate means are employed so that unsaturated bonds of the hydrogen in the potting compound will release less oxygen from the piezoelectric ceramic. One means consists in reducing the concentration of hydrogen in the potting compound, with appropriate thermal processes as a result of which the concentration of hydrogen will be reduced to below a predefined threshold being applied after the piezoelectric actuator has been encased in the potting compound. Means that form bonds with the hydrogen in the potting compound or duct oxygen thereto are provided in further embodiments.

    摘要： A sealing arrangement of a piezoactuator (12) for a fuel injection valve of an internal combustion engine, has connecting pins (14) projecting out of the piezoactuator (12) and a head arrangement (16, 18) placed on to the piezoactuator (12), which is provided with openings (20) for the penetration of the connecting pins (14), wherein a liquid-tight sealing element (30) abuts against the outer surfaces of the connecting pins (14) on one side and also against the head arrangement (16, 18) on the other. In order to ensure a reliable seal with this arrangement, in particular also over extended periods of time, the sealing element (30) abuts against the outer surfaces of the connecting pins (14) located inside the openings (20), and sealing element sections (32) located inside the openings (20) are radially compressed in the openings.
