Abstract:
1. A liquid diffuser device, comprising: a support frame having an upper passageway configured to direct a liquid jet and a lower hollow tubular body defining a first longitudinal axis and provided with a substantially transverse bottom wall; a liquid jet deflecting member having an upper plate located at a predetermined distance from said upper passageway and fixed to a lower stem, said stem defining a second longitudinal axis and being housed into said tubular body; and means for movably coupling said stem to said bottom wall, comprising a lower contact surface of said stem and an upper contact surface of said bottom wall, said contact surfaces being in mechanical communication such to allow rotation of said stem relative to said bottom wall and oscillation of said second axis relative to said first axis responsive to an action of the liquid jet on said plate, wherein said means for removably coupling further comprise an intermediate contact member secured a lower end portion of said stem, said intermediate contact member being configured to continuously contact said upper contact surface of said bottom wall to avoid downward shifting of said stem consequent to wear of said contact surfaces and to keep the distance of said plate from said passageway substantially unchanged, wherein said lower end portion of said stem has a hollow seat downwardly open to provide a housing for said intermediate contact member, wherein said intermediate contact member is stably encased into said hollow seat, wherein said lower contact surface of said tubular body is substantially convex with a predetermined radius of curvature, wherein said bottom wall of said tubular body has a central concave portion housing a first sphere, said first sphere being secured into said concave portion and having an external surface contacting said upper contact surface of said bottom wall, and wherein said intermediate member and said first sphere are aligned along said second axis and in mutual contact relationship at their respective localized areas crossed by said second axis.
