Patent

CA 2336975

An object sensor (18) detects an object such as a hand (20) and operates a valve (52) that permits liquid soap (86) to flow from a disposable soap container (12). The liquid soap is typically quite viscous but tends to be expelled because of pressure applied from a carbon-dioxide cartridge (32). A pressure-regulator assembly (40) permits gas from the carbon dioxide cartridge (32) to enter the soap container (28) only so long as the soap container's internal pressure is less than a predetermined maximum.

L'invention concerne un détecteur (18) d'objets destiné à détecter un objet tel qu'une main (20) et à déclencher une valve (52) permettant à du savon liquide (86) de s'écouler d'un récipient (12) à savon jetable. Le savon liquide qui est, de façon générale, plutôt visqueux, tend à être expulsé du fait de la pression appliquée par une cartouche (32) de dioxyde de carbone. Un ensemble (40) régulateur de pression permet au gaz sortant de la cartouche (32) de dioxyde de carbone de pénétrer dans le récipient (28) à savon pour autant que la pression interne du récipient à savon soit inférieure à un maximum prédéfini.
