Abstract

L'invention concerne un système de dosage destiné à un dispositif de nettoyage (RV) et comprenant un récipient (B) agencé verticalement et muni d'un premier raccordement de fluide (F1) recevant un fluide (F) provenant d'une pompe à fluide (P) et agencé au fond (BO) du récipient (B), et au moins d'un second raccordement de fluide (F2) qui est agencé plus haut que le premier raccordement de fluide (F1) dans la direction verticale, et un dispositif flottant (SW) qui est agencé à l'intérieur du récipient (B), le second raccordement de fluide (F2) placé plus haut et le dispositif flottant (SW) étant réalisés de telle manière que le dispositif flottant (SW) ferme le second raccordement de fluide (F2) lorsqu'il vient en contact avec celui-ci.
