Abstract (en)
[origin: EP0320372A1] 1. A siphon breaking disconnector (13) for supplying a W.C. pan (3) with water from a pressurized mains supply with a view to flushing said W.C. pan, comprising a first, supply pipe (14) capable of being connected at one end to the mains and opening at the other end into an upper chamber (15), said chamber communicating, at its lower part, by an axial injector opening (21) with the top part of a cavity (18) provided with a vent (22) situated downstram of the injector opening, said cavity (18) being finally connected for gravity flow to the pan (3) by a second, evacuation pipe (32), characterized - in that the vent (22) of the cavity consists of the outlet of a spout situated at a first distance (d) from the injector opening, - in that the spout extends externally to the wall of the cavity while sloping slightly upwards (angle alpha) with respect to a plane (26) perpendicular to the axis (19) of the injector opening, - and in that the top part (20) of the cavity (18) comprises a tubular skirt (27) surrounding the outlet of the injector opening and extending therefrom over a distance (d') at least equal to said first distance (d).
