Abstract
An arrangement for supplying and dosing a loose filling material comprises a dosing wheel rotatable in a predetermined direction and having a plurality of dosing chambers movable along a movement path, forming a filling chamber arranged above the movement path of the dosing chamber and limited from below by the dosing wheel and in the direction of rotation by an end wall having a lower edge, a stripper arranged in the region of the lower edge and abutting against the dosing wheel. Means is provided for substantially maintaining a constant filling pressure over a whole opening cross-section of the filling chamber, the maintaining means including a plurality of members having a stepped configuration and disposed on the end wall of the filling chamber, the members being varied in height in response to variations of filling pressure of the filling chamber, so that the filling pressure substantially remains constant by varying the volume of the filling chamber.
