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.

摘要： In a method for pretreating a piezoelectric ceramic (1) and a method for adjusting an injection valve (7), the piezoelectric ceramic (1) is exposed to environmental conditions, leading to a reduction of polarisation and also a reduction of the length of the ceramic (1). The obtained length exhibits a greater long-term stability due to said adjusting phase. Consequently, the injection valve (7) can be re-adjusted before use. As a result, renewed adjustment thereof is required only after a long period in service.

摘要： A method is provided for making electrical contact with an electronic component in the form of a stack formed from a plurality of material layers, which react upon application of an electric field, and a plurality of electrode layers, wherein each material layer is arranged between two of the electrode layers. An insulation structure is generated on at least one stack circumferential region of the stack, which exposes each second electrode layer of the at least one stack circumferential region for electrical contact to be made. Also, a contact-making structure is applied to the at least one stack circumferential region which is provided with the insulation structure. Before the step of generating the contact-making structure, the material layers are partially removed by a material-removing method such that the electrode layers are exposed close to the surface.

摘要： The pre-treatment method for an electromechanical transducer is particularly suitable for polarizing a piezoelectric actuator for an injection system of an internal combustion engine. Prior to the actual operation, the transducer is actuated with an electrical pre-treatment signal, in order to set a predefined operating point in accordance with the pre-treatment signal. The pre-treatment signal corresponds substantially to the electrical actuation signal during normal operation of the transducer, in order to prevent a displacement of the pre-set operating point during normal operation of the transducer.
