Definitions
- the present invention relates to an autonomous underwater respiratory system including a bottle of compressed air that incorporates its own means of air refilling using a manually driven pump.
- the diver can be powered in compressed air from the surface as in the case of a helmet and cable suit, or thanks to a bottle of compressed air carried by the diver.
- the present invention relates to the inflation of the compressed air cylinder.
- the goal aimed at releasing the disadvantages presented above.
- DE-A1-4 341 910 discloses an underwater respiratory system.
- Document DE-4341910 describes an underwater respiratory system comprising a pump arranged outside the system.
- Document DE-25.32.533 describes a system in which the tank remains on the surface. said system comprising a manual pump integrated in the tank.
- the present invention provides a self-respirator underwater of the aforementioned type. It is characterized in particular that the bottle can be pressurized air using an integrated hand pump. Located inside the bottle it allows to pressurize the latter to approximately ten bars.
- This bottle further comprises a loading and unloading valve.
- This device is equipped with a holding assembly fitting on the diver's back.
- the pressurized air of the bottle is transmitted to the diver via a flexible conduit and a pressure reducer a stage that regulates the suction pressure at the ambient pressure of the water.
- the underwater respirator has a mass substantially equal to its volume multiplied by the density of the water in which he is immersed.
- the main advantage of the underwater respirator according to the invention lies in the fact that it allows to inflate the bottle with compressed air without having recourse to a compressor.
- the handle that connects and allows to operate simultaneously the two rods of the pistons must allow, on the one hand to inflate the bottle with both hands and secondly to comfortably carry the bottle.
- a locking system locks the handle in the down position.
- the dual body pump system improves the relationship between the number of pump strokes and efforts to exert on the handle compared to a single pump body.
- the underwater respirator will include a depth clamping system that will reduce the regulator air flow to from a specific depth.
- the self-breathing subaquatic respirator will be equipped with a waterproof pressure gauge to monitor the variation of air pressure in the bottle in immersion only during inflation.
- This manometer is either attached to the bottle or connected Removable way to the loading and unloading valve via a flexible cord.
- This manometer informs the diver of the remaining air autonomy which allows to anticipate the moment of its rise to the surface.
- the auto respirator underwater is equipped with a regulator allowing to deliver to the diver a pressure of air breathable substantially equal to the ambient pressure of the water while the pressure at the inside of the bottle varies during the dive from a dozen bars to 1 bar.
- this regulator is standard second stage type that is used on bottles traditional dives in addition to a first stage regulator.
- the low internal pressure of the bottle does not justify the use of a regulator first stage, the regulator is connected directly to the compressed air cylinder with a quick connector and a hose.
- the internal pressure of the bottle is substantially equal to the ambient pressure of the water, breathing becomes more difficult which tells the diver to go back to the surface.
- the underwater respirator comprises a back support assembly of "straps" type consisting of two straps attached to both ends of the bottle ensuring the vertical maintenance of the latter on the back of the diver and on the other hand a ventral strap "belt” allowing stability horizontal of the bottle.
- the compressed air bottle is attached to a vest for holding on the diver's back.
- Said vest consists of a or several inflatable pockets to act on the buoyancy of the diver.
- the compressed air cylinder includes a support foot for stabilizing said bottle during inflation.
- the diver can thus by putting his feet on these appendages maintain the bottle plated on the ground.
- these appendages are either folded inside a support so as not to annoy the diver in his movements, folded up along the bottle.
- a clamping system (11) of the depth which, for example, will reduce the air flow of the regulator from a given depth, is fixed on the supply duct in air.
- a charge and discharge valve (8) is attached to the top of the bottle.
- a support leg consisting of a support (27) inside which are two telescopic or foldable appendages (13), (14), this to give the bottle greater stability in a vertical position when refilling of the bottle with the pump.
- two vertical straps (32a, 32b) which form a carrying system allowing the diver to carry the bottle on the back while diving.
- the pump comprises two bodies parallel (18) and (19) of equal lengths arranged side by side. These bodies are obstructed by upper part by a plate (5) upper which is also the cap of the bottle (1).
- the lower end of the primary pump body (18) is completely obstructed while that of the secondary pump body (19) has a lower injection port air equipped with a non-return valve (20).
- the two pump bodies (18), (19) are thus secured to the bottle (1) by through the plate (5).
- the pump body (18) constitutes a primary chamber CP, while the body of pump (19) constitutes a secondary chamber CS, the two chambers may have different sections.
- the primary chamber CP receives a piston indicated generally in (17) of the cup comprising a deformable lip (17a) which is adapted at the end of a door rod piston (4) passing through the upper plate (5).
- a seal (23) and a guide ring (21) are housed in the upper plate (5) for sealing and guiding between the latter and the piston rod (4).
- the secondary chamber CS also receives a piston (16) with a cup comprising a deformable lip (16 a) which is fixed at the end of a piston rod (3) passing through the plate upper (5), a seal (22) and a guide ring (21) are housed in the plate upper (5) for sealing and guiding between the latter and the door rod piston (3).
- the pistons (16) and (17) are substantially at the same level within each rooms, so that they are both together at a low point or at a high point, but the lips (16a) and (17a) of the cups are oriented in opposition; more precisely the lip (17a) of the piston (17) of the primary chamber CP is directed upwards, that is to say, to the plate (5), while the lip (16a) of the piston (16) of the secondary chamber CS is directed downwards, that is to say towards the bottom of the body (19).
- the two chambers CP and CS are in communication in upper part for example by means of a channel (24), while in the lower part the chamber CS is in communication with the interior of the bottle through a lower orifice (20) provided with a valve check.
- the rod (4) which carries the piston of the primary chamber is hollow on all its length, its lower orifice opens under the piston (17) while its end upper is clogged. In this way, both chambers (CP, CS) are arranged functionally in series.
- the air inlet is realized by a transverse orifice (26) which is positioned at the level or below the seal when the pump is locked in the down position, but above of the seal when the rod (4) is moved upwards, so as to the primary chamber in communication with the atmosphere.
- the plate (5) is pressed against the orifice of the bottle (1) thanks to a circular flange (6) screwed on the outer contour of the orifice, the seal between the orifice and the plate (5) is provided by an O-ring (25).
- the cups (16a, 17a) of the two pistons (16, 17) therefore divide the inside of the pump body into three compartments whose volumes respective ones vary according to the position of the pistons.
- the first compartment is the one (outlet cavity) delimited below the cup (17a) in the primary chamber (CP).
- the second compartment includes the upper portions (or transfer cavities) primary and secondary chambers, ie those located above the cups (16a, 17a). These two portions are indeed connected by the channel (24) so as to form only one compartment in which the pressure is always uniform.
- the third compartment is the one located below the cup (16a) of the chamber secondary (CS) (and forming output cavity for the secondary chamber).
- the volume of the second compartment decreases, so the pressure of the air contained there tends to increase.
- the air in the second compartment is driven to the third compartment, which is permitted by the orientation of the lip of the cup (16a).
- the final volume of the third compartment is substantially less than the initial volume of the second compartment.
- the volume of the third compartment decreases, which performs a second compression stage of the air contained in this third compartment.
- a limit pressure which is depending on the pressure in the bottle and the calibration of the non-return valve, pressurized air is evacuated, without possibility of return, towards the inside of the bottle through the orifice lower (20).
- the construction with double pistons thus makes it possible to carry out a compression in two floors.
- the compression ratio of the first stage can be modified by modifying the respective volumes of primary and secondary rooms. So with a secondary chamber smaller diameter than the primary chamber, we obtain a compression ratio more high for the first compression stage.
- the dual-stage pumping system compression that is used here is particularly advantageous because it reduces the time needed to refill the bottle.
- a pumping system with stages multiple compressors may be provided, for example having a pump provided as many successive bodies as desired compression stages.
- the auto respirator according to the invention comprises an improved pumping system.
- the mode embodiment of Figure 2 it is a pumping system with two bodies capable to perform a two-stage compression.
- the embodiment of FIG. comprises an outlet cavity (ie a cavity in which the air undergoes a final compression before being expelled to the tank) while in this third mode of realization, the pumping system has two output cavities that can be activated simultaneously or one of which can be disabled.
- the pump comprises two chambers primary (CP) and secondary (CS) cylindrical arranged geometrically parallel to each other, each chamber receiving a piston (46, 48) mounted at the end of a rod (42, 44) movable axially, the two rods being actuated by a common handle (40).
- CP primary
- CS secondary
- the mounting of the pump bodies inside the bottle is identical to that described more high.
- the pistons (46, 48) are sealed pistons that allow no air passage between the room portions they delimit.
- Each chamber thus has an air outlet cavity (50, 52) which, in the embodiment, is constituted by the lower portion of each of the two chambers and which has an air outlet (54, 56) opening into the bottle.
- Each outlet port (54, 56) is associated with a non-return system (58, 60), such that a valve, allowing the passage of air only from the corresponding outlet cavity to inside the bottle.
- each of the two chambers constitutes a transfer cavity (62, 64).
- the two transfer cavities are connected to each other, as before, by a connecting channel (66) to form a transfer compartment similar to the second compartment of the embodiment of the In this embodiment, the transfer compartment has an input air intake (65) which is through a non-return valve (67). This air inlet (65) opens for example in the connecting channel (66).
- the outlet cavity (50) of the primary chamber (CP) is connected to a conduit (68) which allows admission of air into the outlet cavity (50) through a non-return valve (70) preventing the air from coming out.
- This duct further comprises, between the valve (70) and the cavity outlet (50), a bypass (72) which is provided with a shut-off valve (74) and which allows, when the shut-off valve (74) is open, to put the outlet cavity (50) into permanence in communication with the atmosphere. In this configuration, the cavity of output (50) of the primary chamber (CP) becomes inoperative.
- Non-return valves (67, 70) which allow the admission of air into the compartment in the outlet cavity (50) of the primary chamber (CP) are connected to the atmosphere by a common cut-off valve (80) which makes it possible to isolate them from the water at diving court, thus preventing water from entering the pump casings.
- This valve (80) must be open when using the pump to refill the cylinder.
- the transfer cavity 64 of the secondary chamber is connected to the cavity of outlet (52) of this same chamber through a transfer pipe (76) in which is interposed a non-return valve (78) allowing the passage of air only from the compartment of transfer to the outlet cavity (52).
- This tubing (76) with non-return valve, associated with the piston (48), fulfills the same function as the cup piston (16a) of the realization of Figure 2.
- FIG. 5 is a respirator according to a first operating mode in which the shut-off valve (74) is closed.
- the output cavity of the primary chamber is active and may notice that it operates independently of other parts of the pump.
- the piston (46) rises from its low position to its high position, the cavity of outlet (50) from the primary chamber fills with air at atmospheric pressure through the valve (70).
- the piston (46) moves in the other direction, the compressed air in the cavity outlet (50) can not escape through the duct (68) which is closed, and the air is thus expelled towards the inside of the bottle through the valve (58) and the outlet (54).
- the transfer compartment fills with air, by the valve (67) and, when the pistons (46, 48) back up, the gas previously contained in the transfer compartment is transferred by the tubing (76) to the outlet cavity (52) of the secondary chamber (CS).
- the secondary chamber has a volume that is substantially half of that of the primary chamber, so the air is that just been transferred to the outlet cavity (52) is under an absolute pressure of almost 3 bar, thus achieving a first compression stage.
- the piston (48) goes down again, this air is still compressed in the outlet cavity (52) before being expelled inwards from the bottle.
- the pump expels with each return of the pistons a amount of air that corresponds, at atmospheric pressure, to a volume that is close to 2.5 times the volume of the primary chamber.
- FIGS. 2 and 4 are therefore particularly well adapted filling an air tank intended for scuba diving, including a reservoir intended to remain on the surface of the water as in the case of "Hookah". Indeed, they allow (thanks to the two bodies) to recharge the reservoir between two dives in a very short time and at the cost of a moderate effort. In addition, they allow to obtain a sufficiently high pressure in the tank (thanks to the two stages of compression) to store a large amount of air in the tank, allowing the diver to stay longer under water.
