Abstract
The invention concerns a dosing system for adjusting a dose volume of a fluid medium. The dosing system has a longitudinal center axis, a dosing sleeve with at least one communication opening, a dosing plunger, which can move axially in the dosing sleeve between a retracted and a depressed position to take up and dispense the medium through the communication opening, and a retraction limiting element to delimit a maximum axial retraction path of the dosing plunger. The retraction limiting element in at least one position can be axially fixed to the dosing plunger and can move radially to the longitudinal center axis between an inner position, axially fixed on the dosing plunger, and an outer position relative to the dosing plunger. In the inner position, it is completely inside the dosing sleeve. Furthermore, the dosing system has an end stop arranged on the dosing sleeve for interaction with the retraction limiting element in the retracted position of the dosing plunger.
