The invention relates to a hydraulic fire door, especially a sliding door, which can be selectively opened or closed, and the fire door being provided with an actuator (3) for moving said door from an opened position to a closed position. In order to ensure a particularly fire resistant fire door without the heat resistance of the basic structure thereof having to be particularly good, the actuator (3) is arranged to supply aqueous liquid to the fire door in order to cool it using the aqueous liquid. The invention also relates to a fire protection system.
L'invention concerne une porte coupe-feu hydraulique, plus particulièrement, une porte coulissante, pouvant être ouverte ou fermée de manière sélective. La porte coupe-feu est pourvue d'un vérin (3) permettant de déplacer la porte depuis une position ouverte vers une position fermée. Afin de garantir une porte coupe-feu particulièrement résistante au feu, sans que la résistance à la chaleur de la structure de base soit particulièrement bonne, le vérin (3) est conçu pour alimenter la porte coupe-feu en liquide aqueux, lequel permet de refroidir la porte. L'invention concerne également un système de protection contre le feu.
