Anti-noise device and fittings applying to W.C. flushing mechanisms characterised by the fact that the mechanism 5 is housed inside a special tank 6 which is itself placed inside the normal tank 1 of the W.C., that the tank 6 empties directly into the pipe 3 of the bowl via an expulsion orifice 7 which is extended downwards by a conduit 8 of frustoconical shape penetrating inside the expulsion orifice 4 of the tank 1 by bearing against the upper edge 9 of this tank, that a same device provides at the same time the fixing of the mechanism 5 inside the tank 6 and the solid attachment of the tank 1 to the tank 6, the bottom of which is blocked, after flushing, by a sphere 25 which places itself inside the frustoconical conduit 8 and that the system of double enclosure of the noise by means of a special tank such as 6 may also apply to mechanisms of the float cock type.
