    摘要： A seal for a piezoactuator in a fuel injector as simply, reliably and, in respect of the useful life of the piezoactuator, as favorably as possible has a support element (28), positioned on terminal posts (20) projecting in an axial direction (A) out of the piezoactuator (12) and pressed in an axial direction toward a top arrangement (14, 18) of the piezoactuator (20). An external sealing ring (36) is clamped along a circumferential region (14) of the top arrangement between the support element (28) and the top arrangement. Internal sealing rings (38) each enclose one of the terminal posts (20) and are each clamped between a face of the support element (28) facing radially inward and a circumferential face of the terminal post (20).

    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.
