Definitions

- the gas flow from this regulator must be controlled by the diver so that he injects only the amount of gas necessary for the proper conduct of his dive. If the regulator has too large a flow, the quantity of gas injected into the variable capacity will be too large and will modify the buoyancy of the diver and his device.

Description
La présente invention concerne les appareils respiratoires de plongée du type à circuit fermé ou semi-fermé, comprenant une capacité variable, délimitée partiellement par une paroi souple montée par sa périphérie sur un boîtier, communiquant en permanence avec une portion de circuit d'inspiration et une portion de circuit d'expiration et, sélectivement, avec une source de gaz sous pression via un détendeur monté dans le boîtier et commandable par coopération avec la paroi souple.The present invention relates to diving breathing apparatus of the closed or semi-closed circuit type, comprising a variable capacity, partially delimited by a flexible wall mounted by its periphery on a housing, permanently communicating with a portion of the inspiration circuit and a portion of the expiration circuit and, selectively, with a source of gas under pressure via a pressure reducer mounted in the housing and controllable by cooperation with the flexible wall.
Un appareil respiratoire de ce type est décrit dans le document FR-A-1.228.007A respiratory device of this type is described in document FR-A-1.228.007
Dans les appareils respiratoires de ce type, la paroi mobile de la capacité variable, appelée communément "sac respiratoire" ou "faux poumon", est constituée classiquement d'une toile en tissu enduit, volontairement assez rigide pour "durcir" artificiellement l'inspiration et l'injection de gaz sous pression, ce qui rend le travail respiratoire du plongeur relativement important, même quand le détendeur n'est pas sollicité. En effet, dans ce type d'appareil, au fur et à mesure que le plongeur respire, l'oxygène du mélange de gaz sous pression est consommé et transformé en dioxyde de carbone retenu par une couche épuratrice, le gaz ainsi consommé étant remplacé par le gaz sous pression détendu à la pression ambiante quand le plongeur crée une dépression suffisante dans la capacité variable pour que la paroi mobile active le détendeur. Le débit de gaz de ce détendeur doit être contrôlé par le plongeur de façon qu'il n'injecte que la quantité de gaz nécessaire au bon déroulement de sa plongée. Si le détendeur a un débit trop important, la quantité de gaz injecté dans la capacité variable sera trop importante et modifiera la flottabilité du plongeur et de son appareil.In respiratory devices of this type, the movable wall of variable capacity, commonly called "respiratory bag" or "false lung", conventionally consists of a coated fabric canvas, deliberately rigid enough to "harden" the inspiration artificially. and the injection of gas under pressure, which makes the respiratory work of the diver relatively important, even when the regulator is not stressed. Indeed, in this type of device, as the diver breathes, the oxygen in the gas mixture under pressure is consumed and transformed into carbon dioxide retained by a purifying layer, the gas thus consumed being replaced by the pressurized gas expanded to ambient pressure when the plunger creates sufficient depression in the variable capacity for the movable wall to activate the regulator. The gas flow from this regulator must be controlled by the diver so that he injects only the amount of gas necessary for the proper conduct of his dive. If the regulator has too large a flow, the quantity of gas injected into the variable capacity will be too large and will modify the buoyancy of the diver and his device.
Le document US-A-2.900.977 décrit par ailleurs un appareil respiratoire dont la capacité variable, de volume réduit, est formée par une structure composite en accordéon ou en soufflet.Document US-A-2,900,977 also describes a respiratory device whose variable capacity, of reduced volume, is formed by a composite accordion or bellows structure.
La présente invention a pour objet de proposer un agencement permettant de réduire le travail respiratoire fourni par le plongeur tout en conservant une maîtrise parfaite de l'injection du gaz respiratoire dans la capacité variable.The object of the present invention is to propose an arrangement making it possible to reduce the respiratory work provided by the diver while retaining perfect control of the injection of respiratory gas in the variable capacity.
Pour ce faire, selon une caractéristique de l'invention, la paroi souple est constituée d'un diaphragme en matériau élastomère préconformé pour présenter une partie principale et une partie de commande de surface réduite, décalée vers l'extérieur du boîtier par rapport à la partie principale et agencée pour coopérer avec le détendeur.To do this, according to a characteristic of the invention, the flexible wall consists of a diaphragm made of preformed elastomeric material to present a main part and a part of reduced surface control, offset towards the outside of the housing relative to the main part and arranged to cooperate with the regulator.
Selon une autre caractéristique de l'invention, la partie principale est reliée à la périphérie du diaphragme par au moins un pli saillant vers l'extérieur du boîtier.According to another characteristic of the invention, the main part is connected to the periphery of the diaphragm by at least one fold projecting towards the outside of the housing.
Avec un tel agencement, la partie principale du diaphragme, de surface importante et relativement souple, peut se déplacer facilement sous l'action d'une faible variation de pression dans la capacité variable, tant qu'il n'est pas utile de créer dans cette dernière une injection du gaz sous pression. Par contre, la partie de commande, de surface réduite et typiquement plus rigide, ne se déplacera que sous l'action d'une variation de pression conséquente dans la capacité variable, provoquée par le plongeur de façon à venir actionner sélectivement et à bon escient le détendeur.With such an arrangement, the main part of the diaphragm, of large and relatively flexible surface, can move easily under the action of a small pressure variation in the variable capacity, as long as it is not useful to create in the latter an injection of gas under pressure. On the other hand, the control part, of reduced surface and typically more rigid, will only move under the action of a consequent pressure variation in the variable capacity, caused by the plunger so as to come to operate selectively and wisely the regulator.
Cet agencement permet de réduire fortement le travail respiratoire du plongeur, tant que le détendeur n'est pas sollicité. Au moment de l'injection de gaz sous pression dans la capacité variable, le plongeur devra créer une dépression nécessaire au déplacement de la partie de commande du diaphragme, ce qui lui permet de contrôler parfaitement l'injection du gaz sous pression dans l'appareil.This arrangement greatly reduces the breathing work of the diver, as long as the regulator is not stressed. When injecting pressurized gas into the variable capacity, the diver must create a vacuum necessary to move the diaphragm control part, which allows him to perfectly control the injection of pressurized gas into the device .

Sur le fond 2 du boîtier 1 est rapporté un boîtier de détendeur 17 renfermant un clapet 18 coopérant avec un siège de clapet 19 dans lequel débouche le conduit 13 et actionnable, de façon connue en soi, par un levier basculant 20 saillant légèrement dans un évidement 21 du fond du boîtier.As can be seen more clearly in FIG. 2, the

Dans l'exemple représenté, la partie de commande 24 est circulaire et a un diamètre utile d'environ 45 mm. La face interne de la partie de commande 24, coopérant avec le levier 20, peut être pourvue d'un revêtement renforçateur 25.The
