摘要： Der Tintenstrahl-Schreibkopf (1) mit einer in einem Gehäuse (2) angeordneten Tintenkammer (4), in der in einer Frontwand (6) Austrittsöffnungen (14) angeordnet sind, hat Führungsrohre (26), in denen Zugelemente (22) zumindest teilweise geführt sind, und hat Dichtungselemente (36), die jeweils eine Zugvorrichtung gegenüber der Tintenkammer (4) derart abdichten. Die Zugelemente (22) sind axial bewegbar, bei einer kurzzeitigen Betätigung der Zugvorrichtung gelangt Tinte (16) durch die Austrittsöffnung (14) nach außen. Die Führungsrohre (26) weisen einen in die Tintenkammer (4) hineinragenden Tintenkammerabschnitt (28) auf. Jeweils ein Dichtungselement (36) umschließt einen in die Tintenkammer (4) hineinragenden Tintenkammerabschnitt (28) vollständig. Das Dichtungselement (36) bildet mit seinem freien Ende den Schließkörper (20) für die Austrittsöffnung (14). Es ist ein Federring (60) vorgesehen, der mehr als eine Windung aufweist. Die Windungen sind entweder nebeneinander oder übereinander angeordnet. Der Federring (60) umgreift das Dichtungselement (36) im Bereich des Tintenkammerabschnitts (28) außen.

摘要： A fluid ejection device that can be used for inkjet heads is described. A large actuator with a small stroke in combination with hydraulic pressure transfer by means of essentially relatively incompressible fluid is used in order to generate a large stroke of a small membrane. Further the ink is ejected during the actuation phase of the actuator enabling a better control of the droplet dynamics.
