ABSTRACT:
A sealing arrangement of a piezoelectric actuator comprises terminal posts (14) projecting from the piezoelectric actuator and a metallic top arrangement (18, 22), provided with openings (28) allowing the passage of the terminal posts (14) which is emplaced on the piezoelectric actuator. In order to facilitate reliable sealing in particular also for comparatively thin top plates (18), the invention provides for emplacing on terminal post sections (30) projecting from the openings (28) a sealing element (32) which is formed from an electrically insulating and sealing material and which is positioned tight against, on the one hand, circumferential areas (34) of the terminal post sections (30) and, on the other hand, the top arrangement (18, 22), with an insulating disk (40) provided with openings allowing the passage of the terminal posts (14) and made of electrically insulating material being located between the sealing element (32) and the top arrangement (18, 22).
