VOLUMETRIC DOSING DEVICE FOR FILLING MACHINE OF CONTAINERS

摘要

The present invention relates to a metering device (1), comprising: - a metering chamber (4), - a piston (10) separating said metering chamber into a feed compartment (8) and a metering compartment (9), the piston comprising a passage between the two compartments, - a valve (20) closing this passage, allowing the passage of the product when it is in opening osition, - moving means (30) of the valve, the valve comprising means for driving the piston arranged on either side of the piston so that the displacement of the valve in a discharge direction (R) causes the displacement of the piston in the direction of discharge and the movement of the valve along the cylinder body in a transfer direction (T) causes the piston to move in this direction.
