Abstract: The showerhead has a hollow body (10) provided with an inlet nozzle (11) and with a sieve (C) perforated by holes (13) and a cleaning device (40) carrying a plurality of lower pins (41) and displaceable, in the interior of the hollow body (10), between an inoperative position, with the pins (41) spaced from the sieve (C), and an operative position, with each pin (41) introduced into one hole (13) of the sieve (C) and defining at least one water outlet with the hole (13). A driving element (50) is associated with the inlet nozzle (11) and is affixed to the cleaning device (40), in order to maintain it in the inoperative position, while the hydraulic pressure in the inlet nozzle (11) is less than a reference value and displacing the cleaning device (40) to the operative position, when the hydraulic pressure reaches the reference value. A biasing element (60) displaces the driving element (50) and the cleaning means (40) to the inoperative position, when the hydraulic pressure is lower than the reference value.

Abstract: The control valve (R) comprises a body (10) having: an outlet nozzle (12) connected to a flexible conduct (20) whose outlet end (22) is connected to a pistol (30); a sealing seat (S); and a movable sealing means (V) to be displaced between closing and opening positions of the seat (S). A rod (90) has an inner end (91) coupled to the movable sealing means (V), an outer end (92), and a median region (93) mounted in the body (10). The rod (90) may be displaced, in a vertical plane and around a median transversal axis, so as to have its outer end (92) conducted to lowered and raised positions, in which the movable sealing means (V) is conducted to the closing and opening positions of the seat (S). A support (100) is provided in the outer end (92) of the rod (90), in order to receive and retain the pistol (30) when in an inoperative condition, producing the closing of the control valve (R).
