摘要: In a method for producing a piezostack the asymmetry of the electrically inactive zones (2, 2.1, 2.2) in a piezostack (5) having electrically inactive zones (2, 2.1. 2.2) on a plurality of sides thereof is determined, and the electrically inactive zone with an oversize is then reduced until the asymmetry reaches an acceptable proportion.

摘要: The sealing element consisting entirely of elastomer is plugged onto the head plate of a piezo actuator for a fuel injection valve. Encircling sealing bulges (6) are formed on the first end of the sealing element and effect a sealing toward the injector body (2). The sealing element has passages for accommodating contact pins (7), whereby sealing lips (8) are formed around the passages in order to seal the contact pins (7). The sealing actions of the sealing bulges (6) and of the sealing lips (8) are separate from one another.
