Abstract (en)
[origin: WO9927203A1] The invention concerns a plumbing system such as for a water closet, comprising in particular a container (3) to be supplied with water from a supply source, and connected to a wastewater evacuating device such as a siphon (8), in the form of a conduit (21), and comprising means (9) for producing and projecting a jet formed of a liquid and gas mixture, capable of joining the wastewater evacuation stream. The invention is characterised in that the direction of said jet is substantially collinear with the conduit (21) end axis and said means (9) producing and projecting a jet include: a nozzle (10) for projecting water emerging in the upstream part of a low pressure chamber (12), whereof the downstream part emerges in the container (3) bottom; an air intake (11) in the form of a hole arranged at the low pressure chamber (12) side wall; said means (10, 11, 12) being designed so as to produce the air/water mixture downstream of the water projection by the nozzle (10) and at the time of projection into the siphon (8).
