Patent

CA 2167512

The invention relates to a multi-compartment valve device with parallel walls and gas inlet, division plate walls and gas outlet located in such mutual distance from one another, that when the valve device is filled with a deodorizing material, the contact area between the gas and the absorbing means is maximal in regard to the capacity, and the valve device is further filled with a substrate which expands or swells on exposure to moisture, which is located in at least one compartment downstreams of the compartment(s) with the odour-absorbing means.

Dispositif à vanne à plusieurs compartiments, présentant des parois parallèles, un orifice d'entrée de gaz, des parois de séparation et un orifice de sortie de gaz séparés les uns des autres par une distance telle que, lorsque le dispositif est rempli d'une matière désodorisante, la surface de contact entre le gaz et le produit absorbant est maximisée sur le plan de la capacité d'absorption. Le dispositif à vanne est également rempli d'un substrat susceptible de gonfler ou de pendre du volume au contact de l'humidité, ce substrat étant placé dans au moins un compartiment situé en aval du ou des compartiment(s) renfermant le produit absorbant les odeurs.
