CA 2050930

The invention is directed to a novel manually overrideable heat sensitive valve. In a particular embodiment, this invention is directed to a novel faucet aerator which contains the valve. The faucet aerator, when affixed to a water faucet, can stop the flow of water when harmful temperatures are reached. The invention incorporates an external bypass means enabling the user to access higher temperatures when needed or to restart the flow of water. The Anti-Scald Aerator comprises (a) a thermal actuated valving means for automatically restricting the flow of water; (b) air and water mixing means (Aerator Component) for producing a foam-like flow of water; (c) manually operated reset or bypass means for overriding the thermal valve; and (d) connecting housing means for securing the aerator to a water supply.

L'invention concerne un nouveau clapet thermosensible à réouverture manuelle. Dans un mode particulier de réalisation, il s'agit d'un nouvel aérateur à robinet contenant le clapet. Fixé à un robinet à eau, l'aérateur à robinet peut couper l'eau lorsque des températures dangereuses sont atteintes. L'invention comporte un moyen de dérivation externe permettant à l'utilisateur d'obtenir si besoin est de l'eau plus chaude ou de rétablir la circulation d'eau. L'aérateur anti-bouillonnement comprend a) un système de clapet réagissant à la chaleur et permettant de couper l'eau automatiquement; b) un moyen de mélange de l'air et de l'eau (élément aérateur) produisant une eau moussante; c) un moyen de remise à l'état initial ou de dérivation permettant d'annuler l'action du clapet thermique; d) un boîtier de branchement à l'alimentation en eau.
