Abstract
Disclosed is a device for evenly filling or emptying at least one dosing chamber with a product. The device includes a dosing chamber disposed in a dosing disk, the product being dispensed into or emptied from the dosing chamber. A pressure generator impinges the dosing chamber with a predetermined pressure in order fill or empty the dosing chamber. A filter is disposed movably relative to the dosing chamber to assures that once the product has been dispensed, the product can be brought downward into the container to be filled. The filling of the container can be reinforcing by blown air or by transfer dies. The dosing chamber communicates, via the filter means, with the pressure generator. By application of an underpressure, the product to be dosed is dispensed into the dosing chamber. For cleaning the filter means, on the other hand, an overpressure pulse is applied, which improves product dispensing precision.
