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： A drop-detection device detects a drop that escapes from a metering valve. The drop-detection device includes a light guide with first and second light-guiding elements that are arranged opposite each other at an intermediate space. A drop trajectory runs through the intermediate space such that a light beam sent out by the first light-guiding element crosses the drop trajectory and is subsequently coupled into the second light-guiding element. In addition, the drop-detection device includes a light-signal generation device that couples a pulsed light beam with a carrier frequency into the first light-guiding element. Furthermore, the drop-detection device also has a light evaluation device for evaluating the light beam coupled into the second light-guiding element to determine if a drop has been dispensed by the metering valve. A method of detecting a drop is also described.

摘要： A dosing system for a liquid or viscous dosing material, including an actuator system, that has at least one actuating element and a nozzle with an outlet opening. The dosing system is designed so that during a movement in a closure direction the actuating element is initially moved in a first partial movement in such a way that the actuating element is separated from the closure element at a stop location, intended for that purpose, and then comes into contact with the closure element at the stop location and exerts an impulse on the closure element. This also relates to a corresponding dosing method.
