Abstract

Ein Tropfenerzeuger für Mikrotropfen (6), insbesondere ein Düsenkopf für Tintendrucker, mit in einem Gehäuse (11) angeordneten Gruppen von piezoelektrisch betätigbaren Biegewandlern (1), die voneinander beabstandet mittels Wanddicken getrennt in Ausnehmungen geführt sind, mit unterhalb der Biegefinger (5) verlaufenden Flüssigkeits-Längskanälen (12) und einer Flüssigkeitskammer (13) mit einer Düse (7) kann bei ausreichend dicken Kammerwänden, die eine Deformierung nicht zulassen, ein hoher Flüssigkeitsstrom aufrechterhalten werden, indem jeweils um eine Öffnung (14) der Flüssigkeitskammer (13) ein Randwulst (15) verläuft, der als Hubbegrenzung für den Biegefinger (5) dient und indem an die Öffnung (15) ein Schacht (16) zumindest in der Breite des Biegefingers (5) und in der Höhe der Grundplatte (1a) anschließt.
