Abstract

Selon l'invention, une plaque de recouvrement présentant des ouvertures (8) destinées au passage des broches (1) est appliquée sur l'actionneur piézo-électrique et sur les broches de connexion (1). L'invention vise à créer une étanchéification durable, notamment étanche à l'huile, entre l'actionneur piézo-électrique et la métallisation extérieure. A cet effet, chaque ouverture de passage (8) comporte un passage en verre (12) recevant la broche de connexion (1) correspondante de façon centrée, et dans lequel la broche (1) est fondue de façon étanche par rapport à tous les côtés de la paroi de l'ouverture (8) correspondante.
