Les dispositifs décrits dans les deux derniers documents cités ci-dessus sont relativement onéreux, du fait qu'ils doivent comporter autant de réservoirs que de colonnes télescopiques.The devices described in the last two documents cited above are relatively expensive, because they must include as many tanks as there are telescopic columns.
Un objectif de la présente invention est de procurer des installations de lutte automatique contre les incendies de forêts qui sont des perfectionnements des installations décrites dans les deux derniers documents cités et qui permettent de protéger une plus grande surface pour un coût plus réduit.An object of the present invention is to provide automatic fire fighting installations which are improvements to the installations described in the last two documents cited and which make it possible to protect a larger area at a lower cost.
L'objectif de la présente invention est atteint au moyen d'un dispositif pour combattre automatiquement les incendies de forêt à l'intérieur d'un périmètre déterminé qui comporte, en combinaison : - une source d'eau sous pression qui est connectée à un réseau de canalisations enterrées ;The objective of the present invention is achieved by means of a device for automatically fighting forest fires within a determined perimeter which comprises, in combination: - a source of pressurized water which is connected to a network of buried pipelines;
- plusieurs colonnes télescopiques qui sont situé à l'intérieur dudit périmètre, chacune desdites colonnes comportant plusieurs, tubes coulissants coaxiaux, portant à leur sommet un diffuseur d'eau, lesquels tubes sont logés au repos dans un tubage enfoncé verticalement dans le sol, lesquels tubages sont connectés audit réseau de canalisations par leur extrémité supérieure, à un niveau sensiblement égal au niveau desdites canalisations enterrées;- Several telescopic columns which are located inside said perimeter, each of said columns comprising several, coaxial sliding tubes, carrying at their top a water diffuser, which tubes are housed at rest in a casing driven vertically into the ground, which casings are connected to said network of pipes by their upper end, at a level substantially equal to the level of said buried pipelines;
- et des moyens pour détecter la présente d'un feu et pour commander automatiquement l'alimentation en eau desdites colonnes dans le cas où un feu est détecté, ce qui a pour effet d'envoyer dans lesdites colonnes télescopiques, de l'eau sous pression qui provoque la montée des colonnes puis l'arrosage dans ledit périmètre.- And means for detecting the presence of a fire and for automatically controlling the supply of water to said columns in the event that a fire is detected, which has the effect of sending water into said telescopic columns pressure which causes the columns to rise and then sprinkle in said perimeter.
Selon un mode de réalisation particulier, la source d'eau sous pression est constituée par un réservoir central, qui contient de l'eau à la pression atmosphérique et par une source de gaz comprimé qui est connectée audit réservoir central par l'intermédiaire d'une vanne motorisée.According to a particular embodiment, the source of pressurized water is constituted by a central tank, which contains water at atmospheric pressure and by a source of compressed gas which is connected to said central tank by means of a motorized valve.
Avantageusement, l'extrémité inférieure du tube coulissant externe de chaque colonne telescopique porte, à sa périphérie, une pièce de guidage dudit tube coulissant dans ledit tubage, laquelle pièce comporte des cannelures longitudinales séparées par des rainures à travers lesquelles passe l'eau sous pression qui circule dans un espace intermédiaire entre ledit tubage et ledit tube coulissant externe.Advantageously, the lower end of the external sliding tube of each telescopic column carries, at its periphery, a guide part of said sliding tube in said casing, which part has longitudinal grooves separated by grooves through which the water under pressure passes. which circulates in an intermediate space between said casing and said external sliding tube.
L'invention a pour résultat de nouveaux dispositifs de lutte contre les incendies de forêt qui permettent de protéger automatiquement une surface déterminée en évitant, si possible, que le feu n'y pénètre et en éteignant les flammes qui prennent naissance dans cette surface.The invention results in new devices for fighting forest fires which make it possible to automatically protect a given surface by preventing, if possible, that fire enters it and by extinguishing the flames which arise in this surface.
Par rapport aux dispositifs connus comportant chacun un réservoir d'eau et une colonne telescopique qui se replie à l'intérieur de celle-ci, les dispositifs selon l'invention qui comportent une pluralité de colonnes télescopiques alimenté par un réseau de distribution d'eau ou par un même réservoir central*, permettent de protéger une surface plus étendue avec un coût d'installation plus réduit.Compared to known devices each comprising a water tank and a telescopic column which folds inside thereof, the devices according to the invention which comprise a plurality of telescopic columns supplied by a water distribution network or by the same central tank * , protect a larger area with a lower installation cost.
Par rapport aux dispositifs d'arrosage connus comportant une colonne telescopique qui s'escamote au repos dans un tubage, qui est alimenté en eau par son extrémité inférieure, les dispositifs- selon l'invention dans lesquels le tubage est alimenté en eau à proximité de son extrémité supérieure et sensiblement au niveau des canalisations enterrées, permet d'éviter les frais qui étaient nécessaires pour amener l'eau à l'extrémité inférieure du tubage qui peut se situer par exemple à une profondeur de l'ordre de 6 mètres.Compared to known sprinkling devices comprising a telescopic column which retracts at rest in a casing, which is supplied with water by its lower end, the devices according to the invention in which the casing is supplied with water near its upper end and substantially at the level of buried pipes, avoids the costs which were necessary to bring the water to the lower end of the casing which can be located by example at a depth of around 6 meters.
Dans les dispositifs selon l'invention, la quasi totalité du tubage peut être un simple tubage enfoncé dans le sol par les techniques de forage traditionnelles. Seule l'extrémité supérieure du tubage, qui est située dans un regard enterré, est constituée par un manchon spécial portant une ouverture verticale d'entrée d'eau située dans une enceinte en forme de coquille, qui enveloppe ladite ouverture.In the devices according to the invention, almost all of the casing can be a simple casing driven into the ground by traditional drilling techniques. Only the upper end of the casing, which is located in a buried manhole, is constituted by a special sleeve carrying a vertical water inlet opening located in a shell-shaped enclosure, which envelops said opening.
L'alimentation en eau de chaque colonne par l'extrémité supérieure du tubage associée à la bague de guidage cannelée, qui est fixée à la périphérie de l'extrémité inférieure du tube coulissant externe de chaque colonne, présente l'avantage de pouvoir calculer la section des rainures situées entre les cannelures pour obtenir le débit d'eau voulu pour que la montée de la colonne telescopique se fasse à une vitesse déterminée et ne risque pas d'être trop rapide et de détériorer la colonne.The advantage of being able to supply water to each column via the upper end of the casing associated with the grooved guide ring, which is fixed to the periphery of the lower end of the external sliding tube of each column, is to be able to calculate the section of the grooves located between the grooves to obtain the desired water flow so that the rise of the telescopic column takes place at a determined speed and does not risk being too rapid and damaging the column.
De plus, une fois que la colonne est complètement déployée, la pièce de guidage cannelée se trouve placée hors du circuit de l'eau, de sorte que la perte de charge due à cette pièce, qui était bénéfique pendant la montée de la colonne, se trouve supprimée automatiquement à partir du moment où la colonne diffuse de l'eau et la pression de projection de l'eau est donc maxima. ce qui permet d'obtenir une bonne distance de projection de l'eau.In addition, once the column is fully deployed, the grooved guide part is placed outside the water circuit, so that the pressure drop due to this part, which was beneficial during the rise of the column, is automatically removed from the moment when the column diffuses water and the water projection pressure is therefore maximum. which allows to obtain a good projection distance of the water.

La figure 4 est une coupe axiale de l'extrémité supérieure du tubage. La figure 5 est une coupe horizontale selon V-V de la figure 3.Figure 4 is an axial section of the upper end of the casing. FIG. 5 is a horizontal section along V-V in FIG. 3.
La figure 6 est une coupe horizontale selon VI-VI de la figure La figure 1 représente un réservoir central 1 , qui a par exemple une capacité de l'ordre de 5.000 à 8.000 litres et qui est capable de résister à une pression de l'ordre de 6-10*5 pa (g bars).Figure 6 is a horizontal section along VI-VI of the figure FIG. 1 represents a central tank 1, which for example has a capacity of the order of 5,000 to 8,000 liters and which is capable of withstanding a pressure of the order of 6-10 * 5 p a (g bars).
Le réservoir 1 est placé à l'intérieur d'une forêt ou d'un espace boisé que l'on désire protéger automatiquement des incendies. Il contient un liquide extincteur, généralement de l'eau, qui peut être mélangée à un produit retardant la propagation du feu.The tank 1 is placed inside a forest or a wooded space which it is desired to protect automatically from fires. It contains an extinguishing liquid, usually water, which can be mixed with a product that delays the spread of fire.
Le réservoir 1 est associé à une source de gaz comprimé qui est constituée, de préférence, par des bouteilles 2 contenant de l'azote qui sont équipées d'un détendeur et qui sont reliées à l'intérieur du réservoir 1 par l'intermédiaire d'une vanne motorisé non visible sur le dessin.The reservoir 1 is associated with a source of compressed gas which preferably consists of cylinders 2 containing nitrogen which are equipped with a pressure reducer and which are connected to the interior of the reservoir 1 by means of '' a motorized valve not visible in the drawing.
Le réservoir 1 comporte un tube plongeur 3 qui est ouvert à son extrémité inférieure et dont l'extrémité supérieure est reliée à un réseau de canalisations 4 enterrées.The tank 1 comprises a dip tube 3 which is open at its lower end and whose upper end is connected to a network of buried pipes 4.
Une pluralité de colonnes de projection d'eau 5 sont connectées sur le réseau •_ . Chaque colonne comporte un diffuseur 6. qui est placé au sommet d'un tube telescopique composé de plusieurs tubes coaxiaux qui coulissent l'un dans l'autre.A plurality of water spray columns 5 are connected to the network • _. Each column has a diffuser 6. which is placed at the top of a telescopic tube composed of several coaxial tubes which slide one inside the other.
La figure 1 représente les colonnes télescopiques à l'état déployé où elles ont une hauteur supérieure à celle de la végétation qui les entoure, par exemple une hauteur de l'ordre de 25 mètres dans le cas d'une forêt méditerranéenne. Au repos les tubes d'une colonne sont emboîtés les uns dans les autres' et sont contenus â l'intérieur d'un tubage fixe 8, qui est enfoncé verticalement dans le sol et qui a la même hauteur que les tubes composant la colonne.FIG. 1 represents the telescopic columns in the deployed state where they have a height greater than that of the vegetation which surrounds them, for example a height of the order of 25 meters in the case of a Mediterranean forest. Break the tubes in a column are fitted into each other "and are contained within a fixed casing 8, which is pressed vertically into the ground and which has the same height as the tubes making up the column.
Le figure 1 représente un exemple dans lequel les colonnes sont disposées le long de deux lignes pour former un rideau d'eau s'opposant à la progression d'un front de flammes.Figure 1 shows an example in which the columns are arranged along two lines to form a curtain of water opposing the progression of a flame front.
En variante, les colonnes peuvent être disposées sur une ligne courbe entourant une surface à protéger, par exemple un parc ou un espace boisé entourant une maison. Les diffuseurs 6 projettent de l'eau pulvérisée à une distance de l'ordre de 30 mètres et la distance entre les colonnes peut être de l'ordre de 50 mètres.Alternatively, the columns can be arranged on a curved line surrounding a surface to be protected, for example a park or a wooded area surrounding a house. The diffusers 6 project sprayed water at a distance of the order of 30 meters and the distance between the columns can be of the order of 50 meters.
Le dispositif comporte des détecteurs automatiques la qui détectent la présence d'un feu et qui peuvent être par exemple des capteurs à infrarouges ou des capteurs thermiques qui analysent la vitesse de variation de la température.The device includes automatic detectors la which detect the presence of a fire and which can for example be infrared sensors or thermal sensors which analyze the rate of change of temperature.
Lorsqu'un feu est détecté par un des capteurs la, il commande automatiquement l'ouverture de la vanne automatique reliant la source de gaz comprimé au réservoir 1. Le gaz met l'eau sous pression et chasse celle-ci vers le réseau 4. L'eau sous pression provoque le déploiement des colonnes télescopiques et, après déploiement de celles-ci. l'eau pulvérisée est projetée par les diffuseurs 6 et elle arrose la forêt dans un périmètre protégé en évitant que le feu ne puisse pénétrer dans celui-ci et en éteignant les débuts d'incendie qui pourraient intervenir dans ce périmètre.When a fire is detected by one of the sensors 1a, it automatically controls the opening of the automatic valve connecting the source of compressed gas to the reservoir 1. The gas pressurizes the water and drives it to the network 4. The pressurized water causes the telescopic columns to deploy and, after deployment. the sprayed water is projected by the diffusers 6 and it sprinkles the forest in a protected perimeter by preventing that the fire cannot penetrate into it and by extinguishing the beginnings of fire which could intervene in this perimeter.
La durée d'aspersion est généralement supérieure à la durée de passage du front des flammes poussées par le vent, de sorte que lorsque toute l'eau du réservoir 1 a été répandue, en général tout danger d'incendie dans le périmètre protégé est éliminé. II est précisé que l'exemple représenté sur la figure 1 n'est pas limitatif. Le réseau de canalisations enterrées 4 peut être alimenté par n'importe quelle autre source d'eau sous pression, par exemple par une pompe ou par un réseau d'eau alimenté par un réservoir d'eau élevé ou par un réservoir d'eau sous pression. La figure 2 est une vue en élévation à plus grande échelle montrant à gauche une colonne telescopique 5 en position déployée. Cette colonne est composée par exemple de trois tubes coulissants coaxiaux 5^, 52. 53, ayant chacun une longueur de 6 mètres et d'un tubage fixe 8 qui est enfoncé verticalement dans le sol et qui a une hauteur légèrement supérieure à 6 mètres, de sorte que les trois tubes en position rétractée sont contenus dans le tubage 8, comme cela est représenté sur la partie droite de la figure 2.The duration of spraying is generally greater than the duration of passage of the front of the flames pushed by the wind, so that when all the water of the tank 1 has been spilled, in general any danger of fire in the protected perimeter is eliminated . It should be noted that the example shown in FIG. 1 is not limitative. The network of buried pipes 4 can be supplied by any other source of pressurized water, for example by a pump or by a water network supplied by a high water tank or by a water tank under pressure. Figure 2 is an elevational view on a larger scale showing on the left a telescopic column 5 in the deployed position. This column is composed for example of three coaxial sliding tubes 5 ^, 52. 53, each having a length of 6 meters and a fixed casing 8 which is driven vertically into the ground and which has a height slightly greater than 6 meters, so that the three tubes in the retracted position are contained in the casing 8, as shown on the right side of FIG. 2.
L'extrémité supérieure du tubage 8 est située à l'intérieur d'un regard 9 qui est encastré dans le sol. Ce regard 9 contient une vanne motorisée 10 par l'intermédiaire de laquelle l'extrémité supérieure du tubage 8, est connectée au réseau de canalisations 4.The upper end of the casing 8 is located inside a manhole 9 which is embedded in the ground. This manhole 9 contains a motorized valve 10 via which the upper end of the casing 8 is connected to the network of pipes 4.
Le tube coulissant externe 5]_. c'est-à-dire le tube inférieur ayant le plus grand diamètre porte, à son extrémité inférieure, des cannelures longitudinales 11 qui s'appuient contre la paroi interne du tubage fixe 8. de sorte qu'elles guident le tube 5 à l'intérieur du tubage 8 lorsque la colonne monte en ménageant un espace intermédiaire 14 entre le tubage 8 et le tube externe 5 . Les cannelures 11 sont séparées par des rainures.The external sliding tube 5] _. that is to say the lower tube having the largest diameter carries, at its lower end, longitudinal grooves 11 which bear against the internal wall of the fixed casing 8. so that they guide the tube 5 to the inside the casing 8 when the column rises, leaving an intermediate space 14 between the casing 8 and the outer tube 5. The grooves 11 are separated by grooves.
Le tubage 8 comporte, à proximité de son extrémité inférieure, une butée 12, sur laquelle viennent s'appuyer les extrémités inférieures des tubes coulissants 5j_. 5 lorsque la colonne est repliée, de sorte qu'il existe une chambre 13 entre les extrémités inférieures des tubes coulissants repliés dans le tubage et le fond du tubage.The casing 8 comprises, near its lower end, a stop 12, on which the lower ends of the sliding tubes 5j_ come to bear. 5 when the column is folded, so that there is a chamber 13 between the lower ends of the sliding tubes folded in the casing and the bottom of the casing.
Lorsqu'un feu est détecté, l'eau sous pression provenant du réservoir central 1 par le réseau de canalisation enterrées 4 pénètre dans le tubage 8 à proximité du sommet de celui-ci à un niveau qui correspond sensiblement à celui des canalisations 4. L'eau descend en circulant dans l'espace annulaire 14 situé entre le tubage 8 et le tube coulissant externe 5χ. Elle passe dans les rainures situées entre les cannelures 11, arrive dans la chambre 13 et pénètre dans le tube interne 53 par l'extrémité inférieure de celui-ci qui est ouverte.When a fire is detected, the pressurized water coming from the central reservoir 1 through the buried pipe network 4 enters the casing 8 near the top of the latter at a level which corresponds substantially to that of the pipes 4. L water descends by circulating in the annular space 14 located between the casing 8 and the external sliding tube 5χ. It passes through the grooves located between the grooves 11, arrives in the chamber 13 and enters the internal tube 53 through the lower end thereof which is open.
L'eau remplit successivement les tubes 53, 52 et 5ι en les entraînant vers le haut. Lorsque le tube 5^ est monté, les canneluresWater successively fills the tubes 53, 52 and 5ι by driving them upwards. When the tube 5 ^ is mounted, the splines
11 se trouvent placées au-dessus du branchement de la canalisation 4 sur le tubage 8, comme cela est représenté sur la partie droite de la figure 2.11 are placed above the connection of the pipe 4 to the casing 8, as shown on the right-hand side of FIG. 2.
La figure 3 est une coupe axiale d'un mode de réalisation préférentiel d'une colonne telescopique qui représente le tubage 8 d'axe zzl et les trois tubes coulissants 5* . 52. 53 en position repliée à l'intérieur du tubage 8. On voit sur cette figure que le tubage 8 comporte une extrémité supérieure filetée 15, sur laquelle est vissé un manchon fileté 16 qui prolonge le tubage vers le haut. On voit également que le fond du tubage 8 comporte une pièce 17. qui délimite une gorge annulaire 17a, en forme de demi-tore, qui entoure un sommet central. Le bord supérieur de la pièce 17 sert d'appui à un joint annulaire 19, qui est intercalé entre la pièce 17 et l'extrémité inférieure d'une pièce 20 qui est vissée sur l'extrémité inférieure du tube coulissant externe 5^.Figure 3 is an axial section of a preferred embodiment of a telescopic column which represents the casing 8 of axis zzl and the three sliding tubes 5 * . 52. 53 in the folded position inside the casing 8. It can be seen in this figure that the casing 8 has a threaded upper end 15, onto which is screwed a threaded sleeve 16 which extends the casing upwards. It can also be seen that the bottom of the casing 8 comprises a part 17. which delimits an annular groove 17a, in the form of a half-torus, which surrounds a central apex. The upper edge of the part 17 serves as a support for an annular seal 19, which is interposed between the part 17 and the lower end of a part 20 which is screwed onto the lower end of the external sliding tube 5 ^.
La pièce 20 porte à sa périphérie des cannelures longitudinales 11 séparées par des rainures lia, comme on le voit sur la figure 5.The part 20 carries at its periphery longitudinal grooves 11 separated by grooves 11a, as seen in FIG. 5.
L'extrémité inférieure de la pièce 20 coiffe l'extrémité du tube externe 5^ et forme un épaulement contre lequel bute l'extrémité du tube médian 52- Le tube interne 5χ est suspendu au diffuseur 6 qui repose sur l'extrémité supérieure.The lower end of the piece 20 covers the end of the outer tube 5 ^ and forms a shoulder against which the end of the median tube 52- The internal tube 5χ is suspended from the diffuser 6 which rests on the upper end.
On voit sur la figure 3 que les extrémités inférieures des rainures lia sont profilées en forme de déflecteur 11b. L'eau qui progresse suivant les flèches, passe dans les rainures lia et est renvoyée à l'intérieur de la colonne telescopique par la gorge torique 17a.It can be seen in FIG. 3 that the lower ends of the grooves 11a are profiled in the form of a deflector 11b. The water which progresses according to the arrows, passes through the grooves 11a and is returned inside the telescopic column by the toric groove 17a.
La figure 3 représente en pointillés le profil d'une cannelure 11. On voit que l'extrémité supérieure de celle-ci se termine en pointe, de sorte que les rainures lia ont une extrémité supérieure évasée qui facilite l'entrée de l'eau dans les rainures.Figure 3 shows in dotted lines the profile of a groove 11. It can be seen that the upper end of the latter ends in a point, so that the grooves 11a have a flared upper end which facilitates the entry of water in the grooves.
On voit sur la figure 5 que les cannelures 11 sont relativement larges. On détermine leur largeur et donc la section totale des rainures lia situées entre les cannelures pour obtenir un débit d'eau qui correspond à une vitesse déterminée de montée de la colonne, par exemple à une vitesse de l'ordre de 1 m/s. La vitesse de passage de l'eau à travers les rainures lia est déterminée par la différence de pression, c'est-à-dire par la pression du gaz. Le débit d'eau est égal à cette vitesse multipliée par la section totale des rainures et on calcule cette section afin d'obtenir un débit qui correspond à l'augmentation de volume de la colonne lorsque celle-ci monte d'une longueur déterminée, par exemple d'une longueur d'un mètre si on veut obtenir une vitesse d'un mètre par seconde.We see in Figure 5 that the grooves 11 are relatively wide. Their width is determined and therefore the total section of the grooves 11a located between the grooves to obtain a water flow which corresponds to a determined speed of rise of the column, for example at a speed of the order of 1 m / s. The speed of passage of water through the grooves 11a is determined by the pressure difference, i.e. by the pressure of the gas. The water flow rate is equal to this speed multiplied by the total section of the grooves and this section is calculated in order to obtain a flow rate which corresponds to the increase in volume of the column when the latter rises by a determined length, for example one meter long if you want to obtain a speed of one meter per second.
La figure 4 est une coupe axiale d'un mode de réalisation du manchon 16 qui se visse sur l'extrémité supérieure du tubage 8.FIG. 4 is an axial section of an embodiment of the sleeve 16 which screws onto the upper end of the casing 8.
On voit sur cette figure l'extrémité de la canalisation enterrée 4. qui est connectée sur le manchon 16 à un niveau qui est légèrement au-dessus du niveau de la canalisation enterrée.This figure shows the end of the buried pipe 4. which is connected to the sleeve 16 at a level which is slightly above the level of the buried pipe.
Le manchon 16 comporte une ouverture verticale 21 dont la hauteur est supérieure à celle des cannelures 11. Cette ouverture verticale est disposée à l'intérieur d'une enceinte 22 qui l'enveloppe et qui communique par sa base avec la canalisation 4.The sleeve 16 has a vertical opening 21, the height of which is greater than that of the grooves 11. This vertical opening is disposed inside an enclosure 22 which envelops it and which communicates by its base with the pipe 4.
La figure 6 montre une coupe du manchon 16 et de l'enceinte 22 enveloppant l'ouverture 21. Lorsque le tube coulissant externe 5j monte dans le tubage 8, il entraîne avec lui la pièce cannelée 20. Lorsque cette pièce atteint le bas de l'ouverture 21, si une cannelure 11 se trouve en face de l'ouverture 21, elle masque progressivement celle-ci, mais le mélange d'eau et de gaz monte dans l'enveloppe 22 et passe par la partie supérieure de l'ouverture 21, qui n'est pas obturée et redescend à travers les rainures situées entre les cannelures. La section de passage du mélange d'eau et de gaz à travers l'ouverture 21 décroît progressivement, ce qui réduit le débit d'eau et freine la montée de la colonne telescopique juste avant qu'elle heurte la butée haute, ce qui a pour effet bénéfique de réduire l'énergie cinétique de la colonne et donc la violence du choc. Lorsque la colonne est en butée haute, la pièce 20 portant les cannelures 11 se trouve dans la position représentée sur la figure 2. Comme 1'ouverture 21 a une hauteur légèrement supérieure à celle de la pièce 20. l'extrémité inférieure de l'ouverture 21 se trouve située au-dessous de la pièce 20 et l'eau pénètre alors directement dans l'extrémité inférieure du tube externe 5^ et alimente le diffuseur 6, sans subir la perte de charge due au passage à travers les rainures lia. FIG. 6 shows a section of the sleeve 16 and of the enclosure 22 enveloping the opening 21. When the external sliding tube 5 j rises in the casing 8, it carries with it the grooved part 20. When this part reaches the bottom of opening 21, if a groove 11 is located opposite the opening 21, it progressively masks the latter, but the mixture of water and gas rises in the envelope 22 and passes through the upper part of the opening 21, which is not closed and descends through the grooves located between the grooves. The passage section of the mixture of water and gas through the opening 21 decreases progressively, which reduces the water flow and slows the rise of the telescopic column just before it hits the upper stop, which has beneficial effect of reducing the kinetic energy of the column and therefore the violence of the shock. When the column is in high stop, the part 20 carrying the splines 11 is in the position shown in FIG. 2. As the opening 21 has a height slightly greater than that of the part 20. the lower end of the opening 21 is located below the part 20 and the water then penetrates directly into the lower end of the external tube 5 ^ and feeds the diffuser 6, without undergoing the pressure drop due to the passage through the grooves 11a.
