Abstract

L'invention concerne un dispositif de couplage (24) utilisé pour établir une jonction d'écoulement entre un réservoir (6) d'appareil de coupe à vapeur d'eau (1) et une cartouche de liquide (25). Ledit dispositif de couplage (24) présente un boîtier (29) dans lequel est formée une zone de réception (30) dans laquelle une cartouche (25) peut être placée sur le boîtier (29) et qui présente un canal (39) avec un orifice d'entrée (40), qui peut être relié en écoulement avec la cartouche (25) et avec un orifice de sortie (41), qui peut être relié en écoulement avec l'environnement extérieur, par exemple un réservoir (6). Un mécanisme de dosage (38) est disposé dans le boîtier (29) et permet de définir une position de blocage, dans laquelle une cartouche (25) n'est pas placée sur le boîtier (29) et dans laquelle l'orifice de sortie (41) est bloqué. Ledit mécanisme de dosage (38) permet également de définir une position de libération, dans laquelle ledit mécanisme de dosage (38) peut être déplacé, en particulier par mise en place de la cartouche (25) sur le boîtier (29) et dans laquelle l'orifice de sortie (41) est dégagé. L'invention concerne en outre un procédé permettant d'assurer la commande d'un appareil de coupe à vapeur d'eau.
