Abstract

A manifold for a filling unit for filling a plurality of articles with a pourable product is disclosed. The manifold includes a first flange configured to be fixed to a tube for filling a tank with a pourable product; a second flange configured to rotate about an axis with respect to the first flange and be fixed to the tank, the second flange defining a passage for a first fluid other than the pourable product and adapted to be conveyed inside the tank; a fluidic line bounded between the first flange and the second flange and configured to be filled with a second fluid in order to prevent contaminant agents from reaching the passage; a sealing element interposed between the first flange and second flange; at least one piston movable along the axis and operatively connected to the sealing element; and a pneumatic circuit operable to exert a pressure on a third fluid acting on the piston, so as to press the piston against the sealing element along the axis.
