ABSTRACT:
In order to increase the dosing accuracy of a dosing device, the bulk material is temporarily stored upstream from a reservoir (1) in an intermediate storage container (6) and is transferred only when a compensating pressure value is reached. The invention also relates to a corresponding device with a valve lock (4,5) on the intermediate container (6).
