The invention relates to a protection device which defines a through hole (21) for the passage of a fluid which may be under overpressure conditions. In addition, the inventive device comprises: a stop plug (26) which can move between an open position and a position in which a first section of the hole (21) is sealed; a stop valve (28) which can move between an open position and a position in which a second section of the hole (21) is sealed; and means (22, 23, 27) for triggering both the movement of the stop plug (26) and the movement of the valve (28) from the open position to the sealing position in response to an overpressure (P2) in the hole (21). The invention is particularly suitable for self-contained equipment used to supply electrical power by means of a fuel cell.
Ce dispositif de protection délimite un trou traversant (21) pour le passage du fluide pouvant être en surpression. De plus, il comprend : - un obturateur (26) mobile entre une position ouverte et une position d'obturation d'un premier tronçon dudit trou (21), - une soupape d'obturation (28) mobile entre une position ouverte et une position d'obturation d'un deuxième tronçon dudit trou (21), et - des moyens (22, 23, 27) aptes à déclencher à la fois la manAEuvre de l'obturateur (26) et la manAEuvre de la soupape (28) de leurs positions ouvertes vers leurs positions d'obturation, en réponse à une surpression (P2) dans le trou (21). Application notamment à un équipement autonome de fourniture d'énergie électrique au moyen d'une pile à combustible.
