摘要： In a method and arrangement for sealing a piezoactuator having terminal pins (12) protruding from the piezoactuator and a top plate (14) surmounting the piezoactuator, the top plate is provided with openings (16) to enable the terminal pins (12) to pass through. In order to ensure a reliable seal even for comparatively thin top plates (16) in particular, the invention proposes placing an O-ring (28) made from an elastic sealant material on each of the terminal pin sections (30) protruding from the openings (16), so that said O-ring fits tightly to a circumferential surface (32) of the terminal pin section (30), as well as to the top plate (14), forming a seal, and being pressure-injected into the top plate (14) by means of a plastic extrusion coating (arrows in FIG. 1).

摘要： In order to increase the lifetime for a piezoactuator of a fuel injector and to make possible a reliable seal of the piezoactor especially for comparatively thin head plates as well a gas exchange passage running through an actuator housing (52, 54) is provided, where a sealing unit (2) placed on the head arrangement (16, 18) is provided for sealing the piezoactor (12) which features a carrier (28) on which a sealing material (30) is arranged which forms a seal around the piezo contact pins (14) and the head arrangement (16, 18) and on which a microporous gas exchanger (26) to create gas permeability of the sealing unit (24) is integrated such that any fluid which has penetrated through to the gas exchanger (26) can flow out of the gas exchanger (26) under the force of gravity.
