1. Timer-activated self-closing mixing valve consisting of a body (1), a pushbutton (27), a timing piston (11) sliding in a timing chamber (5a) and holding the main valve (10), a seat (7) for the aforementioned valve which is provided on a mixer faucet key (6) adjusting by ist rotation the incoming hot and cold water and forming a mixing chamber (8), a tail (13) on the aforementioned faucet key to drive it in rotation, an outlet chamber (9) for the mixed water and a secondary valve (16) which rests on a secondary seat (17) activated by a spring (18) and a control rod, characterised by the fact that the timing period is set by a timer (15), housed in a box (26), comprising a supported plate with a part (14) linked in rotation to the aforementioned tail (13), and that the timer has a shaft (24) equipped with a V shaped pin (23) which can fit into a notch (22), also V-shaped, provided in an end fitting (21) supported by a tube (19), forming the control rod of the secondary valve, the aforementioned end fitting sliding in the part (14) and by the fact that the secondary valve (16) is formed by a collar of this tube (19) which axially crosses the piston (11) and connects with one end to the timing chamber (5a) and with the other to the outlet chamber (9). |
