Abstract: A filling device for inhomogeneous products or products which have solid or semisolid elements of variable size and compactness in suspensions. In particular, the a filling device for filling machines is provided comprising a hollow body in which a delivery member is movably inserted, wherein the hollow body comprises a lower portion comprising a delivery duct which ends with a delivery opening, said lower portion being intercepted by a cone-shaped rotating shutter, comprising a major base, a minor base and a through hole which is aligned with the delivery duct when the filling device delivers a product, characterized in that the minor base of the rotating shutter is associated with a drawing system, which applies a constant and predetermined drawing force on said minor base. The valve described in the invention can be used in net weight filling machines.

Abstract: A weight filling machine is a volumetric valve type machine. The tank of the product to be dispensed using a hydrostatic flap is replaced by a dispensing system controlled by a volumetric pump. The machine (1) for filling containers (B) with a product includes a carousel (2) for moving the containers (B) and filling valves (5), each filling valve (5) being positioned above a clamp (4). A distribution duct (6) connects the filling valves (5) with a distribution manifold (8). The distribution duct (6) having the product has a filling pressure (P1). A feed duct (9) is intercepted by a volumetric pump (10). The volumetric pump (10) moves a filling product with a discharge pressure (P) greater than the filling pressure (P1) along the feed duct (9). An adjustment member (11) of the feed pressure of the filling product is placed downstream of the volumetric pump (10).
