Abstract: Rotary filling machine for filling containers with liquids, which comprises a rotating carousel (4) having, mounted along its periphery, a plurality of filling valves (6). Each filling valve (6) has an outer pipe (7) for supplying the liquid from a storage tank (20) to a container (30) to be filled with said liquid, and an inner compensation pipe (8) for defining the liquid level inside said container (3) mounted concentrically with the outer pipe (7). Actuator means are envisaged for each filling valve (6) and, by means of transmission means (101), vary simultaneously and in an adjustable manner the vertical position of the compensation pipes (8) of all the filling valves (6) with respect to the position of a seal (13) mounted underneath the tank (20) so as to receive against it the mouth of the containers (3).
