Title (EN) RESPIRATORY PROTECTION HOOD
(FR) CAGOULE DE PROTECTION RESPIRATOIRE
Abstract: front page image
(EN)Hood comprising a flexible envelope (2) and a reservoir (3) of oxygen comprising a calibrated outlet orifice (4) that leads into the internal volume of the envelope (2), the outlet orifice (4) being closed off by a removable stopper (5), characterized in that the reservoir (3) of pressurized oxygen comprises two independent storage compartments (6, 7), a first compartment (6) of which communicates with the outlet orifice (4) and a second compartment (7) of which is isolated from the outlet orifice (4) via a sealed partition provided with a member (8, 9, 10) for opening the partition, the opening member (8, 9) being switchable between a first configuration which prevents fluidic communication between the second compartment (7) and the outlet orifice (4) and a second configuration that allows fluidic communication between the second compartment (7) and the outlet orifice (4), the opening member (8, 9, 10) being sensitive to the pressure difference between the second compartment (7) and the first compartment (6) and being configured to automatically switch from the first to the second configuration when the pressure difference between the second compartment (7) and the first compartment (6) is less than a given threshold.
(FR)Cagoule comprenant une enveloppe (2) souple et un réservoir (3) d'oxygène comprenant un orifice (4) de sortie calibré débouchant dans le volume interne de l'enveloppe (2), l'orifice (4) de sortie étant obturé par un bouchon (5) amovible, caractérisée en ce que le réservoir (3) d'oxygène sous pression comprend deux compartiments (6, 7) de stockage indépendants dont un premier compartiment (6) communique avec l'orifice (4) de sortie et un second compartiment (7) est isolé de l'orifice (4) de sortie via une séparation étanche munie d'un organe (8, 9, 10) d'ouverture de la séparation, l'organe (8, 9) d'ouverture étant commutable entre une première configuration empêchant la communication fluidique entre le second compartiment (7) et l'orifice (4) de sortie et une seconde configuration permettant une communication fluidique entre le second compartiment (7) et l'orifice (4) de sortie, l'organe (8, 9, 10) d'ouverture étant sensible au différentiel de pression entre le second compartiment (7) et le premier compartiment (6) et configuré pour commuter automatiquement de la première à la seconde configuration lorsque le différentiel de pression entre le second compartiment (7) et le premier compartiment (6) est inférieur à un seuil déterminé.
