Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zum Dosieren von Material mit einem festen Kolben (10), einem beweglichen Kolben (12) und einem beweglichen Gehäuse (14) mit einer mit einem der Kolben (10, 12) durch Bewegen des Gehäuses (14) verschließbaren Materialzufuhr (18) und einer mit einem der Kolben (10, 12) durch Bewegen des Gehäuses (14) verschließbaren Materialausfuhr (20), wobei die Achse des festen Kolbens (10) mit der Achse des beweglichen Kolbens (12) fluchtet, zwischen dem festen Kolben (10) und dem beweglichen Kolben (12) zumindest dann ein Abstand im Bereich der Materialzufuhr (18) vorliegt, wenn die Materialzufuhr offen ist und der bewegliche Kolben (12) von einem Piezoaktor (30) ansteuerbar ist. Die Erfindung betrifft ferner ein Verfahren, welches vorteilhaft mit der erfindungsgemäßen Vorrichtung durchgeführt werden kann.

The invention relates to a device for dosing material with a fixed piston (10), a movable piston (12) and a movable housing (14) with a sealable with one of the pistons (10, 12) by moving the housing (14) Material supply (18) and with one of the pistons (10, 12) closable by moving the housing (14) material outlet (20), wherein the axis of the fixed piston (10) is aligned with the axis of the movable piston (12), between the fixed piston (10) and the movable piston (12) there is at least a distance in the area of the material feed (18) when the material feed is open and the movable piston (12) can be controlled by a piezo actuator (30). The invention further relates to a method which can advantageously be carried out with the device according to the invention.
