<p>A liquid diffuser device, comprising a support frame (2) with an upper passageway (3) to direct a liquid jet and a lower hollow tubular body (4) with a bottom wall (5), a liquid jet deflecting member (9) having an upper plate (10) fixed to a lower stem (11) which is had within the tubular body (4), means (13) for movably coupling the stem (11) to the bottom wall (5), comprising at least one lower contact surface (14) of the stem (11) and at least one upper contact surface (15) of the bottom wall (5). The movable coupling means (13) comprise an intermediate contact member (16) secured to the lower end portion (12) of the stem (11), and continuously contacting the upper surface (15) of the bottom wall (5) to avoid downward shifting of the stem (11) consequent to wear of the contact surfaces (14, 15).</p> |
