Plus particulierement, ['invention concerne un dispositif respiratoire permettant a l'homme s d'effectuer des explorations ou des missions subaquatiques sans necessite de remonter en surface pour respirer et, plus specifiquement encore, ['invention est relative a un dispositif More particularly, the invention relates to a respiratory device allowing man s to carry out explorations or underwater missions without the need to rise to the surface to breathe and, more specifically still, the invention relates to a device
respiratoire a recyclage du gaz expire par le plongeur. breathing gas recycling expires by the diver.
Essentiellement, on conna^t, a ce jour des appareils respiratoires pour plongeurs permettant un recyclage du gaz expire par le plongeur, evitant, de ce fait, ['emission de bulles dans le milieu 0 aquatique. Bien que tres repandus, ces dispositifs, a simple flux, presentent plusieurs inconvenients majeurs. Outre leur volume, du a l'encombrement, et leur masse, deux elements determines par la necessite de proteger, contre les chocs, par une coque rigide faisant egalement office de carenage, ltorgane interne, denomme poumon, ils presentent une assez grande insecurite puisque, si la soupape d' aspiration par le plongeur du gaz recycle vient a etre neutralisee par un incident ou endommagee par un accident, le gaz expire par le plongeur ne passe plus a travers la cartouche de filtration du gaz. De meme, si la cartouche de filtration vient a etre hors d'usage, le plongeur ne peut plus respirer de gaz recycle. Dans les deux cas, Essentially, we know, to date, breathing apparatus for divers allowing recycling of the expired gas by the diver, thereby avoiding the emission of bubbles in the aquatic environment. Although widely used, these single-flow devices have several major drawbacks. In addition to their volume, due to the bulk, and their mass, two elements determined by the need to protect, against impact, by a rigid shell also serving as fairing, the internal organ, called lung, they present a fairly great insecurity since , if the suction valve by the recycled gas plunger is neutralized by an incident or damaged by an accident, the gas exhaled by the plunger no longer passes through the gas filter cartridge. Likewise, if the filter cartridge becomes out of order, the diver can no longer breathe recycled gas. In both cases,
au bout de peu de temps, le plongeur ntetant plus alimente en gaz recycle risque l'asphyxie. after a short time, the diver who is no longer supplied with recycled gas risks suffocation.
Le premier but de ['invention est done un but de securite, en proposant un dispositif autonome de respiration subaquatique, d' une conception et d' une realisation economiques, qui permette, avant tout, en evitant ['emission de bulles en milieu aquatique et en conservant l'autonomiede plongee, d'eliminer les risques d'asphyxie du plongeur, grace a un systeme de recyclage du gaz a double flux. Un autre but de ['invention est de permettre a l'utilisateur une plus grande facilite de manutention et une plus grande souplesse d'utilisation du dispositif autonome de respiration subaquatique, ainsi qu'une meilleure mobilite et une plus grande adaptabilite a la morphologic du plongeur, grace a la reduction de masse et de volume de l'appareil, permise par la faculte de pliage du dispositif autonome de respiration subaquatique, autorisee par le systeme de recyclage de l' air a double flux, pliage rendu impossible, dans les The first aim of the invention is therefore a safety aim, by proposing an autonomous device for underwater breathing, of an economic design and realization, which allows, above all, by avoiding the emission of bubbles in an aquatic environment. and retaining the diving autonomy, eliminating the risk of asphyxiation of the diver, thanks to a double flow gas recycling system. Another object of the invention is to allow the user greater ease of handling and greater flexibility of use of the autonomous underwater breathing device, as well as better mobility and greater adaptability to the morphology of the diver, thanks to the reduction in mass and volume of the device, enabled by the folding faculty of the autonomous underwater breathing device, authorized by the double-flow air recycling system, folding made impossible in

La figure 1 montre le schema du circuit respiratoire d'un appareil de respiration subaquatique a simple flux, de l' art anterieur, comportant un embout respirateur ( 1) deux soupapes (2a, 2b) disposees de part et d'autre audit embout respirateur (1), un systeme de compensation du gaz metabolisepar le plongeur, constitue d'une bouteille de gaz comprime (9) munie d'un systeme d'injection (13) dans le circuit respiratoire, un moyen de recyclage constitue d'une cartouche de filtration (3), d'un poumon souple (4). Dans le circuit respiratoire represente, le poumon souple (4) est place en ligne dans ledit circuit respiratoire du gaz entre ladite cartouche de filtration (3) et la soupape (2a), mais il pourrait, dans une autre disposition symetrique, etre place entre la soupape (2b) et la cartouche de filtration (3). Si la soupape (2a), dans la premiere disposition, ou la soupape (2b) dans la deuxieme, venait a etre neutralisee par suite d' incident ou d' accident, le plongeur respirerait, par l' intermediaire de ltembout respirateur ( 1), en pendulaire sur le poumon souple (4). Le gaz expire par le plongeur retournerait alors, dans ledit poumon (4) sans passer par la cartouche de filtration (3), c'est-a-dire sans etre filtre, annulant, de ce fait, toute possibilite de recyclage et pouvant induire, assez rapidement, des risques d'asphyxie du plongeur. Les memes risques seraient encourus par le plongeur en cas d'arrachement ou de deterioration des tuyaux anneles reliant le poumon souple (4) a l'embout FIG. 1 shows the diagram of the respiratory circuit of a single-flow underwater breathing apparatus, of the prior art, comprising a breathing nozzle (1) two valves (2a, 2b) arranged on either side of said breathing nozzle (1), a system for compensating the gas metabolized by the diver, consisting of a compressed gas cylinder (9) provided with an injection system (13) in the respiratory circuit, a recycling means consisting of a cartridge filtration (3), a flexible lung (4). In the respiratory circuit represented, the flexible lung (4) is placed in line in said gas respiratory circuit between said filtration cartridge (3) and the valve (2a), but it could, in another symmetrical arrangement, be placed between the valve (2b) and the filter cartridge (3). If the valve (2a), in the first arrangement, or the valve (2b) in the second, were to be neutralized as a result of an incident or accident, the diver would breathe, via the breathing apparatus (1) , as a pendulum on the flexible lung (4). The gas exhaled by the plunger would then return to said lung (4) without passing through the filtration cartridge (3), that is to say without being filtered, thereby canceling out any possibility of recycling and which may induce , fairly quickly, risks of suffocation of the diver. The same risks would be incurred by the diver in the event of tearing or deterioration of the annealed pipes connecting the flexible lung (4) to the end piece

Si l'une des soupapes (2a, 2b), venait a etre neutralisee par suite d' incident ou d' accident, le plongeur ne respirerait jamais, par l'intermediaire de lt embout respirateur (1), en pendulaire sur le poumon souple (4). Le gaz expire par le plongeur ne pourrait jamais retourner dans ledit poumon souple (4) sans passer par l'une des demies cartouches de filtration (3a, 3b). De ce fait, le gaz est touj ours filtre par l'une des deux demies anterior, a respirator nozzle (1) two valves (2a, 2b) arranged on either side of said respirator nozzle (1), a system for compensating the gas metabolized by the plunger, consisting of a compressed gas cylinder (9 ) provided with an injection system (13) in the respiratory circuit but the recycling means of which consists of two half filtration cartridges (3a, 3b) arranged, in line, on either side of the flexible lung (4 ), go up, him, derivation of the circuit. If one of the valves (2a, 2b) were to be neutralized as a result of an incident or accident, the diver would never breathe, via the breathing apparatus (1), as a pendulum on the flexible lung (4). The gas exhaled by the plunger could never return to said flexible lung (4) without passing through one of the half filtration cartridges (3a, 3b). As a result, the gas is always filtered by one of the two half
cartouches de filtration (3a, 3b) ce qui annule tout risque d'asphyxie du plongeur. filtration cartridges (3a, 3b) which cancels any risk of suffocation of the diver.
Cette disposition accro^t considerablement la securite du plongeur car, tout d'abord, elle permet la respiration, par le plongeur, du gaz recycle par une seule des demies cartouches de filtration (3a, 3b), et de ce fait, elle autorise le remplacement, in situ, c'est-a-dire sous l'eau, 1S d'une des demies cartouches (3a ou 3b) qui viendrait a etre defaillante ou usagee, en la deconnectant et en lui substituant une demi cartouche de filtration (3a ou 3b) neuve. Enfin, lteffort respiratoire fourni par le plongeur pour faire circuler le gaz dans l'appareil est divise par deux par rapport aux systemes classiques a simple flux, puisque a chaque inspiration ou expiration la quantite de chaux traversee par le gaz est reduite de moitie par rapport aux This provision considerably increases the safety of the diver because, first of all, it allows breathing, by the diver, of the gas recycled by only one of the half filter cartridges (3a, 3b), and therefore it allows replacing, in situ, that is to say underwater, 1S of one of the half cartridges (3a or 3b) which would come to be faulty or used, by disconnecting it and replacing it with a half filtration cartridge (3a or 3b) new. Finally, the respiratory effort provided by the diver to circulate the gas in the device is halved compared to conventional single flow systems, since with each inspiration or expiration the amount of lime traversed by the gas is reduced by half compared to to the
systemes classiques a simple flux.classic single flow systems.

Cette faculte d' adaptation a la morphologic du plongeur grace a la variation de l' angle View 3a shows the autonomous underwater breathing device, unfolded, with, on the illustrated variant, the assembly consisting of the cartridge of the respiratory circuit (5) and the flexible lung (4) fixed on a support frame (12) connected to the respiratory circuit cartridge (5) thanks to a connecting beam (6a) and provided with a rotation means, preferably constitutes s 2839944 but in a nonlimiting manner, a ball joint (7), placed on the lower edge to said holding frame (12), in the vicinity of the cartridge of the respiratory circuit (5) surrounded by the strapping (8), on which is fixed the connecting beam (6b) between the cartridge of the respiratory circuit (5) and the bottle of compressed gas (9). At a distance from the edge opposite said flexible lung (4), there is a means of attachment (10) to said flexible lung (4) on said holding frame (12), the rotation means (7), comprising a means of blocking (11) and the fixing means (10) being joined by said holding frame (12). In this view of the folded autonomous device, the flexible lung (4), the cartridge of the respiratory circuit (5) and the compressed gas bottle (9) are in a quasi-alignment, at a variable angle (ot), to allow the adaptation of the autonomous underwater breathing device to the diver's morphology. This faculty of adaptation to the diver's morphology thanks to the variation of the angle
