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.
摘要翻译：描述了一种用于改善封装在含有或形成氢原子的封装化合物中的压电致动器的长期稳定性的方法。氧气被包含在压电致动器的压电陶瓷中。使用合适的方法，使得灌封化合物中的氢的不饱和键将从压电陶瓷释放更少的氧。一种手段在于通过适当的热处理来降低灌封化合物中的氢浓度，由此在将压电致动器封装在灌封化合物中之后，氢的浓度将降低到低于预定阈值。在另外的实施方案中提供了与灌封化合物中的氢形成键或其导管氧的方式。

摘要： A fuel injector has a housing for an actuator (1), especially to a fuel injector with a connector of a contact stud support injection-molded thereto. The injector has a casing (10), disposed across at least part of the periphery of the actuator (1), and an actuator cover (20) placed on the casing (10). The actuator cover (20) is laser-welded to the casing (10) in an overlapping area (30) between the actuator cover (20) and the casing (10). According to a method for finishing the housing of a fuel injector having the aforementioned features, a laser beam used for a laser welding method is incident on the overlapping area (30) in a substantially perpendicular or substantially parallel orientation in relation to the axial direction (A) of the actuator (1) and laser-welds the actuator cover (20) to the casing (10).
