Abstract: A liquid diffuser device for irrigation systems includes a support structure defining a first longitudinal axis with an upper passageway for a liquid jet and a lower tubular body having a bottom wall, a spherical member associated therewith having an outer surface with a predetermined average radius of curvature, a liquid jet deflecting member having an upper plate and a lower stem designed to be introduced into the tubular body and defining a second longitudinal axis. The stem interacts with the outer surface of the spherical member, to allow rotation of the stem relative to the body and nutation of the second axis relative to the first axis. The bottom surface is concave to define with the spherical member a relatively broad and substantially uniform contact surface, to reduce the local specific pressure, thereby decreasing friction, wear and vibrations on the stem and the spherical member during operation.
