Since, as mentioned above, the discharge principle in generic and invention dosing devices provides that in the course of the discharge of the dosing runs along the dosing until it reaches the outlet and closes, the hitherto discharged liquid quantity depends largely on the length of the dosing. Thus, it is possible to adjust over the Solnver Surgi the metering and the respective amount of liquid to be discharged. According to this embodiment, it is provided that such adjustability is given, by which is to be understood that the components defining the end positions can be set in one of several relative positions and in particular relative complaints against each other.
