Beschreibung
Zusammenfassung:	The present invention relates to a dosing systemwith a nozzle having an outlet opening, in the region of which a closure element is movably arranged, which is moved in an ejection and/or retracting direction during operation, wherein the closure element is thus coupled to at least two piezoelectric actuators which are connected in opposite direction such that a first piezoelectric actuator, when it is expanded in operation, moves the closure element in the retracting direction and a second piezoelectric actuator, when it is expanded in operation, moves the closure element in the ejection direction. The invention also relates to a dosing method that can be carried out using such a dosing system and to a method for producing such a dosing system.
