Abstract (en)

[origin: WO2007033909A1] The invention relates to an arrangement comprising a piezoactuator, for example, a piezoinjector which is used to actuate a mechanical component. Said arrangement comprises a multilayered structure of piezolayers (26) which are maintained as piezoelements (3;21) in the maintaining body (2;29,30). Internal electrodes (22, 23) and contact elements (24, 25) are in mutual contact on the piezoelement (3;21) and electric lines (34,35) are guided through the head part (30) of the maintaining body (29) towards the contact elements (24,25). Said electric lines are guided through the head part (30) of the maintaining body (29) towards the contact elements (24, 25) by means of a connecting element (50, 51, 52) which can be adapted to the length thereof. The connecting element consists of an electrically conductive sleeve (50) having a predetermined length, wherein the ends (51) of the electric lines of one part of the connector part can be inserted into one side and on the other side, the ends (52) of the lines can be inserted as extensions of the contact elements (24,25).
