Title (EN) ACTUATOR DEVICE FOR A PRINT HEAD
(FR) DISPOSITIF D’ACTIONNEMENT D’UNE TÊTE D’IMPRESSION
(DE) AKTUATORVORRICHTUNG FÜR EINEN DRUCKKOPF
Abstract:
(EN) Actuator device with a plunger comprising a main body and a plunger, wherein the main body comprises a base body and a cover element, wherein the base body comprises a bottom wall and a circumferential wall which together form a vessel which encloses a chamber and can be closed by means of the cover element, and wherein a passage opening for the plunger is provided in the bottom wall, through which passage opening the plunger protrudes, and an actuating element is provided in the base body, which actuating element is operatively connected to the plunger, wherein the actuating element is configured as a bending transducer which can be divided into a centre region and an edge region, and the bending transducer is arranged with at least part of its edge region on the base body, and the plunger is operatively connected to the bending transducer in the centre region of the latter.
(FR) L’invention concerne un dispositif d’actionnement à coulisseau qui comprend un corps principal et un coulisseau. Le corps principal comprend un corps de base et un élément de recouvrement. Le corps de base comprend une paroi de fond et une paroi périphérique qui forment conjointement un récipient qui renferme un espace et qui peut être fermé au moyen de l’élément de recouvrement et une ouverture de passage du coulisseau est ménagé dans la paroi de fond, ouverture de passage par laquelle le coulisseau fait saillie et un élément de réglage, qui est relié à fonctionnellement au coulisseau, est prévu dans le corps de base. L’élément de réglage est réalisé sous la forme d’un transducteur à flexion qui peut être divisé en une région centrale et une région périphérique, et le transducteur à flexion est disposé, avec au moins une partie de sa région de bord, au niveau du corps de base et le coulisseau est relié fonctionnellement au transducteur à flexion dans la zone centrale de celui-ci.
(DE) Aktuatorvorrichtung mit Stössel umfassend einen Grundkörper und einen Stössel, wobei der Grundkörper einen Basiskörper und ein Deckelelement umfasst, wobei der Basiskörper eine Bodenwand und eine Umfangswand umfasst die zusammen ein einen Raum umschliessendes Gefäss bilden, das mittels des Deckelelementes geschlossen werden kann und wobei in der Bodenwand eine Durchgangsöffnung für den Stössel vorgesehen ist, durch die der Stössel ragt und im Basiskörper ein Stellelement vorgesehen ist, das mit dem Stössel wirkverbunden ist, wobei das Stellelement als Biegewandler ausgebildet ist, der in einen Mittel- und Randbereich unterteilbar ist und der Biegewandler mit zumindest einem Teil seines Randbereichs am Basiskörper angeordnet ist, und der Stössel im Mittelbereich des Biegewandlers mit diesem wirkverbunden ist.
