Prioritet beard fra7n den 8 juli 1943 och den 15 december 1545 (Frankrike). Priority was given on 8 July 1943 and 15 December 1545 (France).

Foreliggande uppfinning avser forbattringar vid andningsapparater for dykare, vilka ap- parater arbeta med oppen krets, d. v. s. 1 vilka den utandade luften icke regenereras genom passerande over ett Iampligt amne .och inandas ph nytt utan utdrives i vattnet. The present invention relates to improvements in breathing apparatus for divers, which apparatus operate with open circuit, i.e. in which the exhaled air is not regenerated by passing over a suitable substance and inhaled ph again but is expelled into the water.

Bifogade ritning visar scan exempel en utforingsform av uppfinningen. The accompanying drawing shows the scan example an embodiment of the invention.

Den visade kretsen ,omfattar en tryckregulator J, ett inandningsror G, ett munstycke F och ett utandningsrtir H, vilket slutar med en -yentil I. Oppningar, som aro upptagna i regulatorns lock E, tillhta vattnet att nava sift tryck ph den yttre ytan av ett membran M. The circuit shown comprises a pressure regulator J, an inhalation tube G, a nozzle F and an exhalation tube H, which terminates with a -enthe I. Apertures, which are accommodated in the regulator cap E, allow the water to nav sift pressure ph the outer surface of a membrane M.

Regulatorn J hr konstruerad sh att den endast verkar, da det tryck, som utovas ph den inre ytan av dess membran M, är lagre an det tryck av vattnet, son) utovas ph dess yttre yta, och nar skillnaden Indian de hada trycken oyerskrider en viss grans, som kan represente- ras ay en vattenpelare av visa hOjd. Ventilen I hr anordnad ph ett aystand Iran membra- nens tryckcentrum, som hr mindre an denna Vilket dykarens lage i vattnet och foljaktligen aven vilken orienteringen av den lin- j e, som gar Iran ventilens utloppsoppning till membranens tryckcentrum, an ar, vare sig denna linje hr vertikal, horisontal eller sned, riktad uppifran nedat eller nedifran uppat, verkar regulatorn .darfor icke, nar dykaren icke inandas. Det fOrekommer alltsh ingen luftfOrbrukning under utandningsperioderna. The regulator J is designed to operate only when the pressure exerted on the inner surface of its membrane M is lower than the pressure exerted by the water, which is exerted on its outer surface, and when the difference between the Indian pressures exceeds one certain spruce, which can be represented by a water column of certain height. The valve I here arranged ph a aystand Iran diaphragm pressure center, which is smaller than this Which diver's position in the water and consequently also what the orientation of the line that goes Iran valve outlet to the diaphragm pressure center, is, whether this line here vertical, horizontal or oblique, directed from the top down or from the top up, the regulator does not work, therefore, when the diver is not inhaled. There is absolutely no air consumption during the exhalation periods.

Nar a andra sidan dykaren genom sin inandning gOr skillnaden mellan de tryck, som rh- da ph membranens bada ytor, storre an det namnda gransvardet, frhn vilket regulatorn trader i funktion, intrader stromning oak forbrukning av tuft Enligt det foregaende skall den angivna gransen vara lagre an dot undertryck, som fbrorsakas av en normal inandning, d. v. S. av storleksordningen 5 till 10 cm vatten. Avstandet mellan utandningsventilen och membranens tryckcentrum skall alltsa sjalvt vara mindre an denna grans. Ventilen hr t. ex. anordnad under regulatorns perforerade lock, vars oppningar da tillata icke endast att vattnets tryck verkar ph membranens yttre yta utan ocksa att den utandade luften avgar till vattnet. When, on the other hand, the diver by his inhalation makes the difference between the pressures which rad- ph the bathing surfaces of the membrane greater than the said spruce value, from which the regulator enters into operation, flow and consumption of tuft enters. lower an dot negative pressure, which is caused by a normal inhalation, i.e. S. of the order of 5 to 10 cm of water. The distance between the exhalation valve and the pressure center of the diaphragm must therefore itself be less than this limit. The valve hr e.g. arranged under the perforated lid of the regulator, the openings of which then allow not only that the pressure of the water acts on the outer surface of the membrane but also that the exhaled air emits to the water.

For att underlatta dykarens andning hr regulatorn anordnad ph honom .sa nara lungorna som mojligt. To facilitate the diver's breathing, the regulator arranged for him to reach as close to the lungs as possible.

Den yid J schematiskt visade regulatorn kan vara fOregangen av en andra regulator D, i vilken har skett en forsta partiell trycksan:kning, eller ocksh kan den vara gjord i tvh eller flera steg eller sektioner, varvid den yid M schematiskt visade membranen da na- turligtvis är den som tillhor det sista trycksakringssteget. The regulator shown schematically may be the precursor of a second regulator D, in which a first partial pressure increase has taken place, or it may also be made in two or more stages or sections, the membrane schematically shown by the yid M fortunately, the one that belongs to is the last pressure protection step.

Dit dykaren spiv mecIfOr sitt andningsluftforrhd, sasom visas ph ritningen, kan denna lull vara innesluten i tva eller flera cylindrar eller flaskor A, B, C, av vilka den ena C kan tjana som reserv och tillhta dykaren att stiga upp tillrackligt langsamt till ytan, nar han genom svarigheten att andas marker, att luftforradet i den eller de ovriga flaskorna Or nara att tommas. Where the diver spits mecIfOr his breathing air condition, as shown in the drawing, this wool may be enclosed in two or more cylinders or bottles A, B, C, one of which C can serve as a reserve and allow the diver to ascend sufficiently slowly to the surface, when he through the responsibility to breathe chips, that the air supply in the other bottle or bottles Or near to be emptied.

Man kan aven astadkomma denna reserv utan att anlita en speciell flaska. I detta syfte mata flaskan eller flaskorna regulatorn Over en ventil, som later gasen passera, da trycket i behallaren eller beliallarna hr hogre som motsvarar ventilens installning, och som automatiskt stoppar avgivningen, da det dessa behallare atersthende trycket blir lika med det installda trycket; det hr under detta hterstaende tryck som gasreserven hr bildad. For att satta denna reserv I tjanst upphaver anvandaren medelst en handmanovreringsanordning verkan av ventilen antingen genom att oppna ett forbiledningsspjall eller genom att paverka en lyftanordning I Or ventilen, ph sadant satt att den i huvudbehallaren kvarvarande gasen pa nytt kan mata apparaten. Ett :satt att forverkliga denna anordning be-star i att som tryckgasbehallare anvanda en flaska med tvh pipar, av -vilka den ena uppbar en kran for gasens stromning mot anvandningsapparaten, varvid ventilen hr an- 2— — bragt p sjal-va inloppet av denna kran till del inre av flaskan. Pa den andra pipen ar anordnat ett handmanovreringsorgan, som kan framkalla ventilens forsattande ur tjanst medelst ett stangsystem eller vilken regaleringsanordning som heist, som är belagen i sjalva kroppen av flaskan och i manOvreringsogonblicket framkallar upplyftningen av yentilen. You can also create this reserve without using a special bottle. To this end, feed the bottle or bottles the regulator over a valve which allows the gas to pass, when the pressure in the container or belts is higher which corresponds to the installation of the valve, and which automatically stops the delivery, when the pressure of these containers becomes equal to the installed pressure; it is under this residual pressure that the gas reserve is formed. In order to put this reserve into service, the user cancels the valve by means of a hand-operated device either by opening a bypass damper or by actuating a lifting device in the valve, in such a way that the gas remaining in the main container can feed the appliance again. One way of realizing this device is to use as a pressurized gas container a bottle with two pipes, one of which carried a tap for the flow of the gas towards the appliance, the valve being placed on the inlet itself. this faucet partially inside the bottle. Arranged on the second spout is a hand actuator which can cause the valve to continue in service by means of a rod system or any control device which is hoisted, which is coated in the very body of the bottle and at the moment of actuation raises the lifting of the yantle.

Claims

1. Patent claim: A breathing apparatus for divers, characterized in that it comprises a diaphragm pressure gulator, the diaphragm whose outer surface is exposed to the pressure of the water and which allows the gas to pass only when some of the pressure on its inner surface is sufficiently much smaller. that which racies on its outer surface, a tube which directs the reduced gas from the regulator to the diver's respirator, and an outlet tube for the exhaled gas terminated by a valve whose distance from the membrane of the membrane of the membrane is less than that of the water column. , .which is due to the difference between the pressure on both surfaces of the diaphragm, over which the regulator is active.
