摘要： The invention describes a dosing system (3) for a shear-thinning or thixotropic liquid to viscous dosing material. It comprises a nozzle (1) with a closure channel (55), within which a closure element (21) is controlled during operation by means of an automatic control unit (63) in an ejection direction (E) and/or retraction direction (R). To this end, the closure channel (55) is realized in at least one cross-section perpendicular to the ejection direction (E) and/or retraction direction (R) relative to the cross-section of the closure element (21) in the same plane to give an aperture gap (57) between the outer surface (S1) of the closure element (21) and the inner surface (S2) of the closure channel (55), which aperture gap (57) is shaped and/or dimensioned to form an outlet channel, at least in places, for the dosing material. The control unit (63) is realized to generate control signals (SS1, SS2) for different movements of the closure element (21) in at least two movement modes (M1, M2, M4, M5, M6), whereby it deliberately moves the closure element (21) during operation in order to reduce the viscosity of the dosing material in at least a region of the aperture gap (57). The invention further describes a method of manufacturing such a dosing system (3), and a dosing method that can be carried out with the dosing system (3).

摘要： 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.
