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