The present invention relates to a dosing
system (3) for a shear-
thinning or thixotropic, liquid to viscous dosing substance. Said dosing
system comprises a
nozzle (1) having a closure channel (55), within which a closure element (21) is moved in an ejection (E) and / or retracting direction (R) and is controlled during operation by an
automatic control unit (63). The closure channel (55) is configured in at least one cross section perpendicular to the ejection (E) and / or retracting direction (R) in relation to the cross section of the closure element (21) in the same
cutting plane such that a passage gap (57) is formed between the outer surface (S1) of the closure element (21) and the inner surface (S2) of the closure channel (55), said closure gap being formed and / or dimensioned such that it forms at least in some regions a passage channel for the dosing substance. Furthermore, the
control unit (63) is designed such that, during operation, it generates control signals (SS1, SS2) for different movements of the closing element (21) in at least two movement
modes (M1, M2, M4, M5, M6), wherein it moves in at least one of the movement
modes (Μ1, M2, M4, M5, M6) the closure element (21) in such a way that the
viscosity of the dosing substance is reduced in at least one region of the passage gap (57). The invention also relates to a method for producing such a dosing
system (3) and to a dosing method that can be carried out using said dosing system (3).
