Abstract
A device for feeding liquid substances in filling machine for filling bottles and the like includes a first tubular member (4), which is integral with a stationary structure (1) of the machine (M) and a second tubular member (5) made integral with a rotating head (6) of the machine (M). The tubular members (4,5) are coaxial and have head surfaces tightly connected to each other by means of a first, upper ring (8) and a second, lower ring (9). The upper ring (8) and lower ring (9) are made of ceramic material and touch each other with their flat surfaces (8A,9A).
