<p>The present invention relates to improvements made to valves having time-delayed automatic shut-off for all fluids, and concerns a device characterised specifically by the fact that said device comprises a hydraulic cartridge having a circuit that is separate from the circuit of the valve as well as time-delayed adjustment of the flow cut-off. The mechanism consists of a control button (18) mounted with a piston (2) which slides axially in said body (1) and separates the fluids found in said body into two areas; same piston is connected to a seal (13) on the jacket (11) which is mounted on the body and comprises holes that communicate with the water or flowing-fluid inlet. When the button is pressed, the fluid trapped inside the body (1) passes from one area to the other inside the chamber, through holes on the shoulder of the piston, and the seal opens and enables the delivery. The fluid returns to area 2 by means of the spring (16) via a hole at the centre of the piston, the cross-section of the outlet of which is adjusted by means of a needle valve (6).</p> |
