Description

La présente invention concerne un dispositif de chasse à cloche flottante, pour réservoir de chasse d'eau de cabinet d'aisances et, plus précisément, un dispositif du genre décrit dans le document FR-A-1 517 475 et comportant un clapet destiné à s'appliquer sur le bord de l'orifice de vidange ménagé dans le fond du réservoir et solidaire, en translation axiale, d'une cloche flottante disposée au-dessus dudit clapet et permettant de le maintenir éloigné de son siège constitué par ledit bord, durant le processus de vidange. Cette cloche flottante est disposée autour de la partie inférieure d'une tige tubulaire, dont l'ex­trémité est équipée du clapet, cette tige étant ouverte à ses extrémités opposées, de manière à constituer un tube de surverse permettant l'évacuation d'un éventuel trop-plein qui pourrait, par exemple, résulter de la fermeture défectueuse du robinet commandant l'admission d'eau dans le réservoir. En outre, cette cloche flot­tante ou cloche intérieure est logée, concentriquement et avec une aptitude de mouvement axial, dans une cloche extérieure de plus grand diamètre constituée par la partie inférieure d'une enveloppe extérieure des­tinée à être installée fixement dans le réservoir, l'entrée supérieure de cette cloche extérieure se trou­vant obturée par le sommet de ladite cloche intérieure mobile, lorsque cette dernière est soulevée en position haute.The present invention relates to a floating bell flushing device, for a toilet flush tank and, more specifically, a device of the type described in document FR-A-1 517 475 and comprising a valve intended for apply to the edge of the drain orifice formed in the bottom of the tank and secured, in axial translation, with a floating bell disposed above said valve and making it possible to keep it away from its seat formed by said edge, during the emptying process. This floating bell is arranged around the lower part of a tubular rod, the end of which is equipped with the valve, this rod being open at its opposite ends, so as to constitute a overflow tube allowing the evacuation of a possible overflow which could, for example, result from the faulty closing of the valve controlling the admission of water into the tank. In addition, this floating bell or inner bell is housed, concentrically and with a capacity for axial movement, in an outer bell of larger diameter constituted by the lower part of an outer casing intended to be fixedly installed in the tank, the upper inlet of this outer bell being closed by the top of said movable inner bell, when the latter is raised in the high position.

De la sorte, lorsque l'équipage mobile du dispo­sitif de chasse est soulevé et que l'eau s'évacue par l'orifice de vidange du réservoir, l'écoulement de l'eau provoque une aspiration de l'air à la base du tube de surverse suivant un débit supérieur au débit de l'air pénétrant à la partie supérieure de l'enveloppe extérieure fixe dudit dispositif, cette aspiration tendant à créer une dépression ou effet de vide dans ladite partie supérieure. Cette dépression ou effet de vide conjuguée à l'effet de flottabilité de la cloche flottante, tend à maintenir l'équipage mobile du dispositif en position haute, durant la vidange du réservoir.In this way, when the moving part of the flushing device is raised and the water is evacuated through the drain opening of the tank, the flow of water causes the air to be sucked in at the base of the overflow tube with a flow greater than the flow of air entering the upper part of the casing fixed exterior of said device, this suction tending to create a vacuum or vacuum effect in said upper part. This vacuum or vacuum effect combined with the buoyancy effect of the floating bell, tends to keep the mobile assembly of the device in the high position, during the emptying of the tank.

Les dispositifs de chasse de ce genre comportent encore un culot pourvu d'un orifice central dont le bord supérieur constitue le siège du clapet ; ce culot étant destiné, d'une part, à être installé fixement sur une ouverture que présente le fond du réservoir et, d'autre part, à permettre la fixation amovible de la partie inférieure du mécanisme de chasse proprement dit dotée de moyens d'assemblage complémentaires.Hunting devices of this kind also include a base provided with a central orifice, the upper edge of which constitutes the seat of the valve; this base being intended, on the one hand, to be installed fixedly on an opening which has the bottom of the tank and, on the other hand, to allow the removable fixing of the lower part of the flushing mechanism proper provided with means of complementary assembly.

Un inconvénient de tels dispositifs de chasse, notamment lorsqu'ils sont installés sur des cuvettes à faible débit de rinçage ou sur des cuvettes à débit d'écoulement moyen, découle du fait qu'il se produit souvent une retombée de leur équipage mobile avant l'achèvement du processus de vidange et, par consé­quent, une application prématurée du clapet sur son siège, de sorte que l'action de rinçage de ladite cuvette est plus ou moins insuffisante.A drawback of such flushing devices, in particular when they are installed on bowls with low rinsing rate or on bowls with medium flow rate, results from the fact that their mobile equipment often falls back before the 'completion of the emptying process and, therefore, a premature application of the valve on its seat, so that the rinsing action of said bowl is more or less insufficient.

Ce fonctionnement imparfait du mécanisme de chasse provient du fait que lorsque la cloche intérieure est soulevée en position haute, l'air pénètre librement entre ladite cloche intérieure mobile et la cloche extérieure fixe, dès que le niveau de l'eau s'évacuant du réservoir s'est abaissé jusqu'au-dessous de la base de ladite cloche extérieure, cette entrée d'air provo­quant l'écoulement de la quantité d'eau précédemment maintenue entre les deux cloches concentriques et permet une circulation d'air en direction de la partie supérieure de l'enveloppe extérieure. La flottabilité de la cloche intérieure devenant insuffisante et l'effet de vide étant supprimé dans la partie supé­rieure de l'enveloppe extérieure, l'équipage mobile du mécanisme de chasse retombe sous l'effet de son propre poids, alors qu'il reste encore un volume d'eau rela­tivement important dans le réservoir.This imperfect operation of the flushing mechanism comes from the fact that when the inner bell is raised in the high position, the air freely enters between said movable inner bell and the fixed outer bell, as soon as the water level discharging from the tank is lowered to below the base of said outer bell, this air inlet causing the flow of the quantity of water previously maintained between the two concentric bells and allows air circulation towards the upper part of the outer casing. The buoyancy of the inner bell becoming insufficient and the vacuum effect being eliminated in the upper part of the outer casing, the moving part of the flushing mechanism falls under the effect of its own weight, while there is still a relatively large volume of water in the tank.

Un but poursuivi par la présente invention est donc d'éliminer l'imperfection de fonctionnement ci-dessus des dispositifs de chasse d'eau du genre susvisé.An object pursued by the present invention is therefore to eliminate the above-mentioned operational imperfection of flushing devices of the aforementioned type.

Selon l'invention, cet objectif est atteint grâce à un dispositif de chasse d'eau de ce genre, caractérisé par le fait que la cloche flottante de son équipage mobile est munie, dans sa partie inférieure, d'un collet obturateur dont le diamètre est à peine infé­rieur au diamètre interne de l'organe cylindrique de la partie fixe dudit dispositif dans lequel il est appelé à se déplacer; un très faible jeu seulement, néces­saire au mouvement axial de ladite cloche flottante, étant ménagé entre la périphérie dudit collet obtura­teur et la paroi interne dudit organe cylindrique.According to the invention, this objective is achieved by means of a flushing device of this kind, characterized in that the floating bell of its mobile assembly is provided, in its lower part, with a shutter collar whose diameter is barely less than the internal diameter of the cylindrical member of the fixed part of said device in which it is called upon to move; only a very small clearance, necessary for the axial movement of said floating bell, being formed between the periphery of said obturating collar and the internal wall of said cylindrical member.

Grâce à cette construction, lorsque l'équipage mobile du dispositif est en position haute et lorsque le niveau de l'eau s'évacuant du réservoir a baissé jusqu'au-dessous du plan dans lequel se trouve disposée la base de la cloche flottante dudit équipage mobile, le collet obturateur constitue un obstacle limitant le débit de l'air s'introduisant entre ladite cloche flottante et la cloche extérieure fixe, ce qui a pour effet de retarder l'écoulement de l'eau présente entre les deux cloches et la retombée de l'équipage mobile pendant une durée suffisante pour permettre la vidange totale ou quasi totale de la cuve ou réservoir et, par conséquent, un rinçage optimum de la cuvette, quel que soit son débit d'écoulement.Thanks to this construction, when the mobile assembly of the device is in the high position and when the level of water discharging from the reservoir has dropped to below the plane in which the base of the floating bell is located. movable assembly, the shutter collar constitutes an obstacle limiting the flow of air entering between said floating bell and the fixed external bell, which has the effect of delaying the flow of water present between the two bells and the fallout of the moving element for a sufficient time to allow the total or almost total emptying of the tank or tank and, consequently, optimum rinsing of the bowl, whatever its flow rate.

On se réfère auxdits dessins pour décrire un exemple d'exécution avantageux, quoique nullement limitatif, de ce dispositif.Reference is made to said drawings to describe an advantageous, although in no way limiting, embodiment of this device.

Selon ce mode d'exécution intéressant, ce dispositif comprend, de façon connue, une enveloppe tubulaire extérieure 1 comportant une portion supé­rieure cylindrique 1a et une portion inférieure renflée ou cloche extérieure 1b. L'extrémité supérieure de la portion haute 1a de cette enveloppe extérieure est munie d'un chapeau 1c pourvu d'un orifice axial taraudé 1d.According to this interesting embodiment, this device comprises, in known manner, an outer tubular casing 1 comprising a cylindrical upper portion 1a and a bulged lower portion or outer bell 1b. The upper end of the upper portion 1a of this outer casing is provided with a cap 1c provided with a tapped axial orifice 1d.

Dans l'enveloppe extérieure 1, est logé, avec une aptitude de mouvement axial ascendant ou descendant, un tube de "surverse" ou tube d'évacuation de trop-plein 2 à l'extrémité inférieure duquel est fixé le clapet 3 d'obturation de l'orifice de vidange du réservoir. Ce clapet est, par exemple, constitué par un joint d'étanchéité en forme de couronne circulaire installé dans une gorge périphérique que présente une monture 2a constituant l'extrémité inférieure du tube de surverse 2.In the outer casing 1, is housed, with a capacity for axial upward or downward movement, a "overflow" tube or overflow discharge tube 2 at the lower end of which the shutter valve 3 is fixed. from the tank drain hole. This valve is, for example, constituted by a seal in the form of a circular crown installed in a peripheral groove that has a mount 2a constituting the lower end of the overflow tube 2.

La portion inférieure dudit tube de surverse est agencée de manière à constituer un flotteur. Ce flot­teur est formé par une cloche 4 disposée autour de la portion basse du tube de surverse 2 et dont le bord inférieur est placé au-dessus et à distance réduite du plan dans lequel se trouve la face supérieure du clapet 3, ladite cloche étant fermée à son sommet et ouverte à sa base.The lower portion of said overflow tube is arranged so as to constitute a float. This float is formed by a bell 4 disposed around the lower portion of the overflow tube 2 and the lower edge of which is placed above and at a reduced distance from the plane in which the upper face of the valve 3 is located, said bell being closed. at its top and open at its base.

La cloche flottante intérieure 4 est logée, concentriquement, dans la cloche extérieure 1b et un espace annulaire a est réservée entre les parois latérales cylindriques de ces deux cloches. Lorsque la cloche intérieure 4 est soulevée en position haute, elle bute, par l'intermédiaire de son sommet 4a, contre le fond 1b' de la cloche extérieure 1b, en fermant l'ouverture supérieure b de cette dernière.The inner floating bell 4 is housed, concentrically, in the outer bell 1b and an annular space a is reserved between the cylindrical side walls of these two bells. When the inner bell 4 is raised in the high position, it abuts, via its top 4a, against the bottom 1b 'of the outer bell 1b, closing the upper opening b of the latter.

Le dispositif de chasse comprend également un système de commande comportant, par exemple, un bouton-poussoir 5, mobile axialement et verticalement. Ce bouton-poussoir est guidé dans la partie supérieure d'un évidement axial 6a dont est pourvu un bouton de calage fixe 6 comportant une tige tubulaire 6b dotée d'un filetage extérieur sur au moins sa portion inférieure. La tige tubulaire 6b est vissée dans l'écrou constitué par le chapeau 1c formant le sommet de l'enveloppe extérieure 1.The flushing device also comprises a control system comprising, for example, a push button 5, which can move axially and vertically. This push button is guided in the upper part of an axial recess 6a which is provided with a fixed setting button 6 comprising a tubular rod 6b provided with an external thread on at least its lower portion. The tubular rod 6b is screwed into the nut constituted by the cap 1c forming the top of the outer envelope 1.

D'autre part, un tel dispositif comprend encore un culot 7 comportant un orifice central 0 dont le bord circulaire supérieur 7a forme le siége du clapet 3.On the other hand, such a device also comprises a base 7 comprising a central orifice 0 whose upper circular edge 7a forms the seat of the valve 3.

Le culot 7 et la base de la cloche extérieure 1b sont pourvus de moyens de jonction complémentaires permettant de les assembler de manière amovible, tout en autorisant le passage de l'eau entre ladite base et ledit culot.The base 7 and the base of the outer bell 1b are provided with complementary joining means allowing them to be assembled in a removable manner, while allowing the passage of water between said base and said base.

Lorsque le dispositif de chasse est installé dans un réservoir lui-même fixé sur une cuvette 19 de cabinet d'aisances partiellement représentée à la figure 1, il est immobilisé à l'intérieur dudit réservoir :
- d'une part, au moyen du bouton de calage fixe 6 prenant appui sur la face supérieure du couvercle 8a (partiellement représenté aux figures 1, 6 et 7) du réservoir et dont la tige 6b traverse un orifice 9 ménagé dans ledit couvercle, et,
- d'autre part, au moyen du culot 7 installé fixement, à l'aide d'un écrou 10 se vissant sur sa portion cylindrique inférieure filetée 7b, dans l'orifice 11 que présente le fond 8 du réservoir (partiellement illustré aux figures 1, 2, 6 et 7), de sorte que l'orifice central 0 dudit culot constitue l'orifice de vidange du réservoir. L'étanchéité entre le fond du réservoir et le culot est réalisée au moyen d'un joint 12 en caoutchouc.When the flushing device is installed in a tank itself fixed on a toilet cabinet bowl 19 partially shown in FIG. 1, it is immobilized inside said tank:
on the one hand, by means of the fixed timing button 6 bearing on the upper face of the cover 8a (partially shown in FIGS. 1, 6 and 7) of the tank and the rod 6b of which passes through an orifice 9 formed in said cover, and,
- on the other hand, by means of the base 7 fixedly installed, using a nut 10 screwed onto its threaded lower cylindrical portion 7b, in the orifice 11 presented by the bottom 8 of the tank (partially illustrated in the figures 1, 2, 6 and 7), so that the central orifice 0 of said base constitutes the emptying orifice of the tank. The seal between the bottom of the tank and the base is made by means of a rubber seal 12.

Le culot 7 porte une traverse 13 disposée fixement au travers de son orifice central 0, au-dessous du siège 7a du clapet 3. Sur cette traverse 13, prend appui l'organe de soulèvement dudit clapet, constitué par une came 14 disposée au-dessous de celui-ci et monté avec une aptitude de pivotement à l'extrémité inférieure d'une tige de transmission 15 susceptible d'être repoussée par le bouton-poussoir 5.The base 7 carries a cross-member 13 fixedly disposed through its central orifice 0, below the seat 7a of the valve 3. On this cross-member 13, the lifting member of said valve is supported, constituted by a cam 14 arranged at- below it and mounted with a pivoting ability at the lower end of a transmission rod 15 capable of being pushed back by the push button 5.

L'intérêt de ce mécanisme de soulèvement du clapet, dans son application au dispositif de chasse selon l'invention, est qu'il n'existe aucune liaison mécanique entre l'équipage mobile 2-3-4 et l'organe 14 de soulévement de celui-ci. De la sorte, lorsque la cloche flottante 4 se déplace vers le haut sous l'effet de sa flottabilité, après soulèvement du clapet, elle s'auto-positionne contre le fond de la cloche extérieure fixe 1b, en obturant ainsi parfaitement l'entrée supérieure b de cette dernière.The advantage of this valve lifting mechanism, in its application to the flushing device according to the invention, is that there is no mechanical connection between the moving assembly 2-3-4 and the lifting member 14 of it. In this way, when the floating bell 4 moves upwards under the effect of its buoyancy, after lifting the valve, it self-positions against the bottom of the fixed outer bell 1b, thereby perfectly closing the upper inlet b of the latter.

Le dispositif de chasse selon l'invention est principalement remarquable par le fait que la cloche flottante intérieure 4 est munie, dans sa partie inférieure, de préférence à sa base, d'un collet obturateur 4b dont le diamètre D est à peine inférieur au diamètre d de l'organe cylindrique de la partie fixe du dispositif de chasse dans lequel ledit collet est appelé à se déplacer, lors des mouvements axiaux de ladite cloche intérieure. Un très faible jeu, néces­saire au mouvement axial de la cloche intérieure, est ainsi ménagé, dans cette position, entre la périphérie du collet obturateur 4b et la paroi interne dudit organe cylindrique.The flushing device according to the invention is mainly remarkable in that the internal floating bell 4 is provided, in its lower part, preferably at its base, with a shutter collar 4b whose diameter D is barely less than the diameter d of the cylindrical member of the fixed part of the flushing device in which said collar is called upon to move, during the axial movements of said inner bell. A very small clearance, necessary for the axial movement of the inner bell, is thus provided, in this position, between the periphery of the shutter collar 4b and the internal wall of said cylindrical member.

Suivant le mode d'exécution avantageux illustré, cet organe cylindrique est constitué par un fourreau d'étanchéité 16 formé d'une seule pièce avec le culot 7 et rigidement rattaché à ce dernier par l'intermédiaire des fourchettes de verrouillage 17 espacées et équidistantes dont est muni ledit culot, de façon connue en soi, pour permettre sa fixation à la base de la cloche extérieure 1b. Dans ce cas, le collet obturateur 4b a une largeur sensiblement égale à la largeur de l'espace annulaire compris entre la surface extérieure de la paroi latérale 4d de la cloche intérieure 4 et la surface interne du fourreau d'étanchéité.According to the advantageous embodiment illustrated, this cylindrical member is constituted by a sealing sheath 16 formed in one piece with the base 7 and rigidly attached to the latter by means of the locking forks 17 spaced apart and equidistant from which is provided with said base, in a manner known per se, to allow its attachment to the base of the outer bell 1b. In this case, the shutter collar 4b has a width substantially equal to the width of the annular space between the outer surface of the side wall 4d of the inner bell 4 and the inner surface of the sealing sleeve.

Ce fourreau cylindrique 16 est disposé au-dessus et à distance du siège 7a du clapet et son diamètre exté­rieur est sensiblement égal au diamètre interne de la partie inférieure cylindrique 1b" de la cloche exté­rieure 1b dans laquelle ledit fourreau est engagé sans jeu notable, lorsque le culot 7 est assemblé à la base de ladite cloche extérieure.This cylindrical sheath 16 is disposed above and at a distance from the seat 7a of the valve and its external diameter is substantially equal to the internal diameter of the cylindrical lower part 1b "of the external bell 1b in which said sheath is engaged without significant play, when base 7 is assembled at the base of said outer bell.

Afin d'autoriser le guidage de la cloche intérieure 4 lorsque le dispositif de chasse est muni d'un méca­nisme de commande à bouton-poussoir du genre illustré et précédemment décrit, ou d'empêcher la rotation de ladite cloche lorsque ledit dispositif est équipé d'un mécanisme de commande à tirette ou à bouton-poussoir d'un autre type, l'ensemble constitué par les four­chettes de verrouillage 17 et par le fourreau 16 solidaire de celles-ci, et la cloche intérieure 4, sont agencés de manière complémentaire, de façon à permettre les mouvements axiaux de cette dernière tout en interdisant sa rotation autour de son axe.In order to authorize the guiding of the internal bell 4 when the flushing device is provided with a push-button control mechanism of the kind illustrated and previously described, or to prevent the rotation of said bell when said device is equipped with '' a pull or push button control mechanism of another type, the assembly constituted by the locking forks 17 and by the sheath 16 integral with these, and the internal bell 4, are arranged in a complementary manner , so as to allow the axial movements of the latter while preventing its rotation about its axis.

Cet agencement complémentaire comprend, par exemple, d'une part, des nervures longitudinales 18 que présente la face interne de l'ensemble constitué par les fourchettes de verrouillage 17 et le fourreau 16 et, d'autre part, des encoches 4c ménagées à la périphérie du collet obturateur 4b et dans lesquelles sont engagées lesdites nervures. Les nervures 18 s'étendent de la base des fourchettes de verrouillage 17 jusqu'à l'extrémité ou bord supérieur du fourreau 16.This complementary arrangement comprises, for example, on the one hand, longitudinal ribs 18 which have the internal face of the assembly constituted by the locking forks 17 and the sheath 16 and, on the other hand, notches 4c formed at the periphery of the shutter collar 4b and in which said ribs are engaged. The ribs 18 extend from the base of the locking forks 17 to the end or upper edge of the sleeve 16.

Selon le mode d'exécution illustré (figure 3), le culot 7 comporte trois fourchettes de verrouillage verticales 17 dont les centres sont espacés de 120 degrés. Dans ce cas, l'ensemble 16-17 comporte trois nervures longitudinales 18 espacées de 120 degrés, tandis que le collet obturateur 4a est doté de trois encoches 4b également distantes de 120 degrés et dans lesquelles sont engagées lesdites nervures.According to the illustrated embodiment (Figure 3), the base 7 has three vertical locking forks 17 whose centers are spaced 120 degrees. In this case, the assembly 16-17 comprises three longitudinal ribs 18 spaced 120 degrees apart, while the shutter collar 4a is provided with three notches 4b also spaced 120 degrees apart and in which said ribs are engaged.

On décrit ci-après le fonctionnement du dispositif de chasse selon l'invention.The operation of the hunting device according to the invention is described below.

En période de remplissage ou d'inactivité (figure 1), l'équipage mobile 2-3-4 du dispositif est en position basse et le clapet 3 repose sur son siège 7a et obture l'orifice de vidange 0. Le collet obturateur 4b de la cloche intérieure 4 est disposé au-dessous et à distance du bord inférieur du fourreau cylindrique 16 et, compte tenu du fait que l'eau contenue dans le réservoir 8-8a peut pénétrer dans l'espace annulaire a en passant entre les portions inférieures des four­chettes de verrouillage 17 et circuler librement dans cet espace, elle remplit également la totalité de l'espace a-c existant entre ladite cloche intérieure et la cloche extérieure 1b, et aussi l'espace annulaire d ménagé entre le tube de surverse 2 et la portion cylindrique 1a de l'enveloppe fixe extérieure 1. Le niveau de l'eau contenue dans le réservoir se situe généralement un peu au-dessous de l'emplacement où se trouve l'extrémité supérieure du tube de surverse vertical et celui-ci peut remplir sa fonction en cas de fermeture défectueuse du robinet d'alimentation.During the filling or inactivity period (Figure 1), the mobile equipment 2-3-4 of the device is in the low position and the valve 3 rests on its seat 7a and closes the drain orifice 0. The obturator collar 4b of the internal bell 4 is arranged below and at a distance from the lower edge of the cylindrical sheath 16 and, taking into account the fact that the water contained in the reservoir 8-8a can enter the annular space a passing between the lower portions of the locking forks 17 and circulate freely in this space, it also fills the entire space ac existing between said inner bell and the outer bell 1b, and also l annular space d formed between the overflow tube 2 and the cylindrical portion 1a of the outer fixed envelope 1. The level of the water contained in the reservoir is generally a little below the location where the he upper end of the vertical overflow tube and it can fulfill its function in the event of a faulty closing of the supply valve.

Lorsqu'on actionne le mécanisme de commande du dispositif de chasse, le clapet 3 est décollé de son siège 7a et la poussée ascendante qui s'exerce sur la cloche flottante 4 assure la remontée de l'équipage mobile jusqu'à ce que le sommet 4a de ladite cloche vienne s'appuyer contre le fond 1b' de la cloche extérieure 1b, en fermant l'ouverture supérieure b de cette dernière de sorte que les passages annulaires a et d ne se trouvent plus en communication (figure 6). Lors de la montée de la cloche intérieure, une faible quantité d'eau demeure, d'une part, dans au moins la partie inférieure de l'espace annulaire d et, d'autre part, dans l'espace annulaire a. L'eau qui s'évacue du réservoir par l'orifice de vidange 0, selon flèches F, a pour effet de créer une aspiration d'air selon flèche F1 à la partie inférieure du tube de surverse 2. La quantité d'air qui est évacuée de l'enveloppe exté­rieure 1 par cet effet d'aspiration étant supérieure à la quantité d'air qui pénètre à la partie supérieure de ladite enveloppe, il se crée, à l'intérieur de celle-ci, un vide partiel qui conjugué aux forces ascendantes F2 auxquelles est soumise la cloche intérieure 4 en raison de sa flottabilité, concourt au maintien en position haute de l'équipage mobile 2-3-4 du dispositif de chasse.When the control mechanism of the flushing device is actuated, the valve 3 is detached from its seat 7a and the upward thrust which is exerted on the floating bell 4 ensures the ascent of the mobile assembly until the top 4a of said bell comes to bear against the bottom 1b 'of the outer bell 1b, closing the upper opening b of the latter so that the annular passages a and d are no longer in communication (Figure 6). When the inner bell rises, a small amount of water remains, on the one hand, in at least the lower part of the annular space d and, on the other hand, in the annular space a. The water which evacuates from the tank through the drain port 0, according to arrows F, has the effect of creating an air suction according to arrow F1 at the lower part of the overflow tube 2. The amount of air which is evacuated from the outer casing 1 by this suction effect being greater than the quantity of air which penetrates at the upper part of said envelope, a partial vacuum is created inside it which, combined with the ascending forces F2 to which the inner bell 4 is subjected due to its buoyancy, contributes to maintaining the moving equipment 2 in the high position -3-4 of the hunting device.

Durant le processus d'évacuation, la baisse de la hauteur de la colonne d'eau annulaire retenue entre les parois cylindriques 4d, 1b" des cloches intérieure 4 et extérieure 1b, respectivement, ne suit pas la baisse du niveau de l'eau contenue dans le réservoir, à l'exté­rieur de l'enveloppe extérieure 1, à laquelle elle devrait normalement correspondre en vertu du principe des vases communiquant, en raison du fait que la pré­sence du fourreau d'étanchéité 16 et du collet obtura­teur 4b constitue un obstacle contrariant l'écoulement de l'eau emprisonnée entre lesdites parois, en direction de l'orifice de vidange 0.During the evacuation process, the drop in the height of the annular water column retained between the cylindrical walls 4d, 1b "of the inner 4 and outer bells 1b, respectively, does not follow the drop in the level of the water contained in the tank, outside the outer casing 1, to which it should normally correspond by virtue of the principle of communicating vessels, owing to the fact that the presence of the sealing sheath 16 and the obturating collar 4b constitutes an obstacle obstructing the flow of water trapped between said walls, towards the drain orifice 0.

Lorsque le niveau de l'eau s'évacuant du réservoir s'est abaissé jusqu'au dessous de la base de la cloche extérieure 1b (figure 7), la présence du fourreau 16 et du collet 4b contrecarre la pénétration de l'air dans l'espace annulaire a et, par conséquent, retarde aussi l'écoulement de l'eau retenue dans cet espace. L'étan­chéité entre les espaces a et d est ainsi maintenue pendant une durée supplémentaire lors de laquelle l'équipage mobile 2-3-4 est tenu en position haute et cette durée est suffisante pour permettre une vidange totale ou quasi totale de la cuve ou réservoir. L'en­trée d'une certaine quantité d'air dans l'espace a met ensuite fin à l'étanchéité entre ledit espace et l'es­pace d, ce qui provoque la retombée dudit équipage mobile, l'application du clapet 3 sur son siège 7a et la fermeture de l'orifice de vidange 0.When the level of water evacuating from the tank has dropped to below the base of the outer bell 1b (FIG. 7), the presence of the sheath 16 and the collar 4b counteracts the penetration of air into the annular space a and, therefore, also delays the flow of water retained in this space. The tightness between the spaces a and d is thus maintained for an additional period during which the mobile assembly 2-3-4 is held in the high position and this period is sufficient to allow a total or almost total emptying of the tank or tank. The entry of a certain amount of air into space a then ends the seal between said space and space d, which causes the fallout of said mobile assembly, the application of the valve 3 on its seat. 7a and closing the drain port 0.
