ABSTRACT:
A rotary liquid container-filling machine has valve assemblies (3), mounted on a rotating platform (2), each of provided with a duct (4) intercepted by an obturator (5) for regulating the supply of liquid from a storage tank (6) to the container (7) and having an air return pipe (8). A centering cone (10) receives in abutment the mouth of the container (7) to cause opening of the obturator (5) mounted at the bottom of each valve assembly (3). A flushing station (14) associated with the rotating platform (2), but fixed with respect thereto, is provided with at least one collecting tray (15) which is moved by a linear actuator (16) so as to be positioned underneath the valve assemblies (3) passing above it. For this purpose first a actuator means (17) opens each obturator (5) when valve assemblies (3) pass above the collecting tray (15). Each valve assembly (3) also has a blow-in pipe (23) provided with an outlet mouth (60) connected to the bottom end of the pipe (4) to introduce inert gas inside the container (7) to be filled before, during and after a step involving filling of the container (7) itself. Each air return pipe (8) has a third valve (31) which is actuated to open and close by activation means (32) which is integral with the centering cone (10).
