Description

La présente invention concerne un mécanisme de chasse à double commande permettant de réaliser, au choix de l'utilisateur, la vidange complète ou l'évacuation partielle du réservoir de chasse d'eau.The present invention relates to a dual control flushing mechanism making it possible, at the user's choice, to completely empty or partially drain the flush tank.

On a déjà proposé des mécanismes de chasse permettant d'interrompre, à volonté, la vidange du réservoir de chasse, lorsqu'on estime qu'un lavage ou rinçage suffisant de la cuvette se trouve réalisé avant que la totalité de l'eau contenue dans ledit réservoir n'ait été évacuée (FR-A-2609297, FR-A-2621630, FR-A-2658844), c'est-à-dire avant l'achèvement du processus normal de chasse, de sorte qu'il est ainsi possible de réaliser des économies d'eau appréciables.Hunting mechanisms have already been proposed making it possible to interrupt, at will, the emptying of the cistern, when it is estimated that sufficient washing or rinsing of the bowl is carried out before all of the water contained in said tank has not been evacuated (FR-A-2609297, FR-A-2621630, FR-A-2658844), that is to say before the completion of the normal hunting process, so that it is thus possible to achieve significant water savings.

A l'exception du système de chasse d'eau décrit dans le document FR-A-2609297, les différents dispositifs proposés pour l'obtention du résultat susmentionné, ont pour inconvénient de nécessiter deux actions successives et espacées sur la commande du mécanisme de chasse. Or, les utilisateurs ou usagers ne prennent pas toujours le temps, après avoir actionné une première fois l'organe de commande, de s'assurer qu'un rinçage suffisant de la cuvette a été obtenu avant vidange complète, pour actionner une seconde fois ledit organe de commande entrainant l'interruption de l'écoulement d'eau, de sorte que d'importantes quantités d'eau se trouvent inutilement consommées.With the exception of the flushing system described in document FR-A-2609297, the various devices proposed for obtaining the above-mentioned result have the drawback of requiring two successive and spaced-apart actions on the control of the flushing mechanism. . However, the users do not always take the time, after having actuated the control unit for the first time, to ensure that sufficient rinsing of the bowl has been obtained before complete emptying, in order to actuate said a second time control unit causing the water flow to be interrupted, so that large quantities of water are unnecessarily consumed.

Le document FR-A-2609297 décrit un système de chasse d'eau dont le but est de permettre d'obtenir un débit d'eau adapté à chaque utilisation de la chasse d'eau. Toutefois, ce système met en oeuvre un dispositif de commande à deux organes d'actionnement fonctionnant par traction et dont la manipulation est particulièrement malaisée. Pour obtenir la vidange partielle, il faut, en effet, maintenir un organe appuyé pendant qu'on soulève le second, et cela pendant toute la durée de la vidange partielle.The document FR-A-2609297 describes a flushing system, the aim of which is to enable a water flow rate suitable for each use of the flushing to be obtained. However, this system implements a control device with two actuating members operating by traction and whose handling is particularly difficult. To obtain partial emptying, it is necessary, in fact, to keep one member pressed while the second is being lifted, and this throughout the duration of the partial emptying.

La présente invention a notamment pour but de supprimer la nécessité d'actionner deux fois l'organe de commande du mécanisme de chasse, pour obtenir l'interruption de la vidange, de façon à limiter la quantité d'eau évacuée, sans que cela entraine une complication du geste à réaliser pour les utilisateurs.The object of the present invention is in particular to eliminate the need to actuate twice the control member of the flushing mechanism, to obtain the interruption of the emptying, so as to limit the quantity of water discharged, without this causing a complication of the gesture to perform for users.

L'invention se rattache plus précisément aux mécanismes de chasse du genre comportant :

  • d'une part, un équipage mobile monté avec une aptitude de déplacement axial et comprenant un clapet d'obturation de l'orifice de vidange du réservoir, installé à la partie inférieure d'un tube d'évacuation de trop-plein ou tube de surverse comportant un orifice supérieur et un orifice inférieur, la portion inférieure de ce tube de surverse étant agencée ou conformée pour constituer un flotteur disposé au-dessus dudit clapet, ce flotteur étant submersible, comme décrit dans le document FR-A- 2658844, et étant équipé, dans ce but, d'un obturateur mobile axialement et verticalement, cet obturateur pouvant être plaqué contre son siège constitué par le bord de l'orifice inférieur du tube de surverse, de façon à empêcher l'entrée d'eau dans le flotteur, ou éloigné dudit siège sous l'impulsion d'un organe de poussée ou de butée, de façon à permettre une entrée d'eau dans ledit flotteur entrainant la retombée rapide de celui-ci et l'interruption du processus de chasse ;
  • d'autre part, un système de commande par bouton-poussoir.
The invention relates more precisely to hunting mechanisms of the kind comprising:
  • on the one hand, a mobile assembly mounted with an axial displacement aptitude and comprising a shutter valve for the emptying port of the tank, installed at the lower part of an overflow discharge tube or overflow comprising an upper orifice and a lower orifice, the lower portion of this overflow tube being arranged or shaped to constitute a float disposed above said valve, this float being submersible, as described in document FR-A-2658844, and being equipped, for this purpose, with a shutter movable axially and vertically, this shutter being able to be pressed against its seat constituted by the edge of the lower orifice of the overflow tube, so as to prevent the entry of water into the float, or distant from said seat under the impulse of a pushing or abutment member, so as to allow water to enter said float causing it to drop rapidly and the process to be interrupted hunting us;
  • on the other hand, a push button control system.

Le mécanisme de chasse selon l'invention est remarquable par le fait qu'il comprend deux systèmes de commande distincts à bouton-poussoir, soit un premier système de commande à bouton-poussoir incluant un dispositif de transmission permettant le soulèvement de l'équipage mobile, et un deuxième système de commande à bouton-poussoir comprenant un dispositif de transmission permettant le positionnement de l'obturateur du flotteur submersible en position d'ouverture, ces deux systèmes de commande étant agencés de manière que l'actionnement de la commande de soulèvement de l'équipage mobile n'entraîne aucune action sur la commande de déplacement de l'obturateur du flotteur submersible, tandis que l'actionnement de la commande d'ouverture dudit obturateur entraine automatiquement l'actionnement de la commande de soulèvement de l'équipage mobile.The flushing mechanism according to the invention is remarkable in that it comprises two systems of separate push-button controls, i.e. a first push-button control system including a transmission device allowing the lifting of the moving assembly, and a second push-button control system comprising a transmission device allowing the positioning of the shutter of the submersible float in the open position, these two control systems being arranged so that the actuation of the lifting control of the moving assembly does not cause any action on the movement control of the shutter of the submersible float, while actuation of the opening control of said shutter automatically causes actuation of the lifting control of the moving element.

Selon une autre disposition caractéristique de l'invention, des moyens maintiennent le système de déplacement de l'obturateur du flotteur submersible dans la position d'ouverture dudit obturateur, pendant le remplissage dudit flotteur entrainant la retombée de ce dernier.According to another characteristic arrangement of the invention, means maintain the displacement system of the shutter of the submersible float in the open position of said shutter, during filling of said float causing the latter to fall back.

Grâce à l'invention, l'utilisateur ou l'usager peut, en fonction de la quantité d'eau qu'il estime nécessaire pour assurer un bon nettoyage de la cuvette, soit obtenir la vidange complète du réservoir en actionnant le système de commande permettant le soulèvement de l'équipage mobile du mécanisme de chasse, soit obtenir la vidange partielle dudit réservoir, correspondant par exemple sensiblement à une demi-vidange de celui-ci, en actionnant le système de commande d'ouverture de l'obturateur du flotteur submersible entraînant simultanément l'actionnement du système de commande de soulèvement de l'équipage mobile.Thanks to the invention, the user or the user can, depending on the amount of water he deems necessary to ensure good cleaning of the bowl, or obtain complete emptying of the tank by actuating the control system allowing the lifting of the movable assembly of the flushing mechanism, or obtaining the partial emptying of said tank, corresponding for example substantially to a half-emptying thereof, by actuating the opening control system of the float shutter submersible, simultaneously actuating the lifting system for the moving part.

Les quantités d'eau évacuées par la mise en oeuvre de l'un ou l'autre des processus de chasse ci-dessus ne peuvent être modifiées, tandis que ces processus ne peuvent être interrompus, lorsqu'ils ont été enclenchés, ce qui assure, dans tous les cas, un bon nettoyage ou rinçage de la cuvette.The quantities of water evacuated by the implementation of one or other of the above flushing processes do not can be modified, while these processes can not be interrupted, when they have been started, which ensures, in all cases, a good cleaning or rinsing of the bowl.

On se reporte auxdits dessins pour décrire deux exemples de réalisations avantageux, quoique non limitatifs, du mécanisme de chasse selon l'invention, lequel peut être exécuté en toutes matières plastiques présentant les qualités requises.Reference is made to said drawings to describe two examples of advantageous, although not limiting, embodiments of the flushing mechanism according to the invention, which can be made of any plastic material having the required qualities.

Sur les dessins annexés, les organes du mécanisme de chasse qui sont les mêmes ou qui accomplissent des fonctions identiques dans les deux modes d'exécution, sont désignés par les mêmes références.In the accompanying drawings, the parts of the flushing mechanism which are the same or which perform identical functions in the two embodiments, are designated by the same references.

Selon le mode d'exécution illustré aux figures 1 à 5, le mécanisme de chasse comprend, de façon connue, une enveloppe extérieure désignée dans son ensemble par la référence 1 et comportant une portion supérieure cylindrique 2 de guidage et une portion inférieure renflée ou cloche extérieure 3, également cylindrique, et dont le diamètre est nettement supérieur à celui de ladite portion supérieure de guidage, cette enveloppe extérieure étant destinée à être installée fixement dans le réservoir de chasse, comme cela est décrit dans la suite du présent exposé.According to the embodiment illustrated in Figures 1 to 5, the flushing mechanism comprises, in known manner, an outer casing designated as a whole by the reference 1 and comprising a cylindrical upper guide portion 2 and a lower portion bulging or outer bell 3, also cylindrical, and whose diameter is significantly greater than that of said upper guide portion, this outer casing being intended to be fixedly installed in the flush tank, as described in the remainder of this description .

Dans l'enveloppe extérieure 1, est logé, avec une aptitude de mouvement axial ascendant ou descendant, un tube de "surverse" 4 comportant un orifice inférieur A et un orifice supérieur B, de manière à permettre une décharge automatique d'un éventuel trop plein qui pourrait, par exemple, résulter de la fermeture défectueuse du robinet commandant l'admission d'eau dans le réservoir. Sur l'extrémité inférieure de ce tube, est fixé le clapet 5 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 et exécuté en caoutchouc ou autre matériau analogue, installé dans une gorge périphérique que présente une monture 4a constituant l'extrémité inférieure du tube de surverse 4 et le bord de l'ouverture A.In the outer casing 1, is housed, with a capacity for axial upward or downward movement, a "overflow" tube 4 comprising a lower orifice A and an upper orifice B, so as to allow automatic discharge of any excess full which could, for example, result from the faulty closing of the tap controlling the admission of water into the tank. On the lower end of this tube, is fixed the valve 5 for closing the tank emptying orifice. This valve is, for example, constituted by a seal in the form of a circular crown and made of rubber or other similar material, installed in a peripheral groove that has a mount 4a constituting the lower end of the overflow tube 4 and the edge of opening A.

La partie inférieure du tube de surverse est agencée ou conformée de manière à constituer un flotteur, lequel peut être avantageusement formé par la portion inférieure renflée 6 dudit tube, la base de ce flotteur étant placée au-dessus et à distance réduite du plan dans lequel se trouve la face supérieure du clapet 5.The lower part of the overflow tube is arranged or shaped so as to constitute a float, which can advantageously be formed by the bulged lower portion 6 of said tube, the base of this float being placed above and at a reduced distance from the plane in which is the upper side of the valve 5.

Le flotteur 6 est logé concentriquement, dans la cloche extérieure 3 et un espace ou passage annulaire C est réservé entre les parois latérales cylindriques de ces deux organes.The float 6 is housed concentrically in the outer bell 3 and an annular space or passage C is reserved between the cylindrical side walls of these two members.

D'autre part, la partie supérieure du tube de surverse 4 est logée, également concentriquement, dans la portion supérieure 2 de l'enveloppe extérieure 1, qui lui sert de guide, un espace annulaire D étant ménagé entre les parois latérales cylindriques dudit tube et de ladite portion supérieure.On the other hand, the upper part of the overflow tube 4 is housed, also concentrically, in the upper portion 2 of the outer casing 1, which serves as a guide, an annular space D being formed between the cylindrical side walls of said tube and of said upper portion.

Le tube de surverse 4, le flotteur 6 et le clapet 5, constituent l'équipage mobile du mécanisme de chasse.The overflow tube 4, the float 6 and the valve 5, constitute the mobile assembly of the flushing mechanism.

Le siège du clapet 5 est constitué par le bord circulaire supérieur 7 d'un orifice central E dont est pourvu un culot désigné dans son ensemble par la référence 8.The seat of the valve 5 is constituted by the upper circular edge 7 of a central orifice E which is provided with a base designated as a whole by the reference 8.

Lorsque le mécanisme de chasse est positionné à l'intérieur d'un réservoir de chasse lui-même fixé sur une cuvette de cabinet d'aisances, le culot 8 est installé fixement, au moyen d'un écrou (non représenté) se vissant sur la portion cylindrique inférieure filetée 8a dudit culot, dans l'orifice 9 que présente le fond 10 du réservoir (partiellement représenté aux figures 1 et 3 à 5). De la sorte, l'orifice central E du culot 8 constitue l'orifice de vidange du réservoir. L'étanchéité entre le fond 10 du réservoir et l'assise ou face d'appui du culot 8, est réalisée au moyen d'un joint annulaire intermédiaire 55 exécuté en caoutchouc ou autre matériau adéquat.When the flushing mechanism is positioned inside a flushing tank itself fixed on a toilet bowl, the base 8 is installed fixedly, by means of a nut (not shown) screwed onto the threaded lower cylindrical portion 8a of said base, in the orifice 9 presented by the bottom 10 of the reservoir (partially shown in Figures 1 and 3 to 5). In this way, the central orifice E of the base 8 constitutes the emptying orifice of the tank. The seal between the bottom 10 of the tank and the seat or bearing face of the base 8 is produced by means of an intermediate annular seal 55 made of rubber or other suitable material.

La base de la cloche extérieure 3 et le culot 8 sont agencés de manière complémentaire ou pourvus de moyens de jonction complémentaires permettant de les assembler rigidement, de manière amovible, tout en autorisant le passage de l'eau entre ladite base et ledit culot. Le culot 8 est, par exemple, pourvu de trois fourchettes de guidage et de verrouillage 11 espacées de 120 degrés et entre les branches desquelles est engagée et retenue la base 3a de la cloche extérieure 3, les branches internes 11a de ces fourchettes de verrouillage 11 étant pourvues de nervures verticales 11b servant de guides au flotteur 6, lors des mouvements verticaux de celui-ci.The base of the outer bell 3 and the base 8 are arranged in a complementary manner or provided with complementary joining means allowing them to be rigidly assembled, in a removable manner, while allowing the passage of water between said base and said base. The base 8 is, for example, provided with three guide and locking forks 11 spaced 120 degrees apart and between the branches of which the base 3a of the outer bell 3 is engaged and retained, the internal branches 11a of these locking forks 11 being provided with vertical ribs 11b serving as guides for the float 6, during the vertical movements of the latter.

Le flotteur 6 est un flotteur submersible du genre de celui qui est décrit dans le document FR-A-2.658.844. Il est équipé d'un obturateur 12 mobile axialement et verticalement, cet obturateur étant logé, concentriquement, dans le flotteur 6 duquel il émerge par sa partie inférieure munie d'une collerette operculaire 12a. Cette dernière constitue une soupape qui peut être plaquée contre son siège constitué par le bord de l'orifice inférieur A du tube de surverse, en assurant ainsi la flottabilité du flotteur, ou éloignée dudit siège, de manière à permettre une entrée d'eau dans ledit flotteur. entrainant la submersion de celui-ci et, par conséquent, la retombée du clapet 5 sur son siège 7.The float 6 is a submersible float of the type described in document FR-A-2,658,844. It is equipped with a shutter 12 movable axially and vertically, this shutter being housed, concentrically, in the float 6 from which it emerges through its lower part provided with an opercular flange 12a. The latter constitutes a valve which can be pressed against its seat constituted by the edge of the lower orifice A of the overflow tube, thereby ensuring the buoyancy of the float, or remote from said seat, so as to allow water to enter the said float. causing the latter to submerge and, consequently, the valve 5 to fall back onto its seat 7.

L'obturateur 12 comporte avantageusement un corps tubulaire, de préférence cylindrique, dont le sommet est pourvu d'une paroi supérieure ajourée, par exemple constituée par une barrette transversale 12b au centre de laquelle est ménagé un trou 13 pour le passage d'une tige de transmission 14. D'autre part, le corps tubulaire de l'obturateur est pourvu, extérieurement et latéralement, d'une ou plusieurs ailettes de butées 12c disposées à distance de la collerette operculaire 12a, ces ailettes étant logées à l'intérieur du flotteur 6.The shutter 12 advantageously comprises a tubular body, preferably cylindrical, the top of which is provided with a perforated upper wall, for example constituted by a transverse bar 12b at the center of which is provided a hole 13 for the passage of a rod transmission 14. On the other hand, the tubular body of the obturator is provided, externally and laterally, with one or more stop fins 12c arranged at a distance from the opercular flange 12a, these fins being housed inside the float 6.

Selon l'invention, le mécanisme de chasse comprend deux systèmes de commande distincts à bouton-poussoir, soit :

  • un premier système de commande à bouton-poussoir incluant un système de transmission ou timonerie permettant le soulèvement de l'équipage mobile 4-5-6, et,
  • un deuxième système de commande à bouton-poussoir comprenant un système de transmission ou timonerie permettant le déplacement de l'obturateur 12 du flotteur submersible 6, par rapport à ce dernier.
According to the invention, the flushing mechanism comprises two separate push-button control systems, namely:
  • a first push-button control system including a transmission or wheelhouse system allowing the lifting of the mobile equipment 4-5-6, and,
  • a second push-button control system comprising a transmission or wheelhouse system enabling the shutter 12 of the submersible float 6 to be moved relative to the latter.

Selon le mode d'exécution illustré aux figures 1 à 5, le système de commande permettant le soulèvement de l'équipage mobile 4-5-6, comprend :

  • un premier bouton-poussoir 15 mobile verticalement et logé dans une coupelle 16 appelée à être installée fixement dans une ouverture 17 ménagée dans le couvercle 18 du réservoir ;
  • un ressort 19 agissant en compression et tendant à repousser le bouton-poussoir 15 vers l'extérieur, c'est-à-dire vers le haut ; ce ressort étant par exemple calé, par l'intermédiaire de ses extrémités opposées, d'une part, contre la face inférieure 15a dudit bouton-poussoir et, d'autre part, contre le fond 16a de la coupelle 16 ;
  • la tige de transmission 14 qui peut être entrainée en translation axiale vers le bas, par le bouton-poussoir 15, cette tige de transmission traversant longitudinalement l'équipage mobile 4-5-6 ;
  • et un organe de soulèvement 20 monté avec une aptitude de pivotement à l'extrémité inférieure de la tige de transmission 14 et disposé au-dessous du clapet 5 et de la collerette operculaire 12a de l'obturateur ; cet organe de soulèvement est, par exemple, constitué par une came ou par un petit levier du premier type dont l'axe d'oscillation 21 est porté par une traverse 22 disposée fixement à travers l'orifice d'évacuation E du culot 8, au-dessous du siège 7 du clapet 5.
According to the embodiment illustrated in FIGS. 1 to 5, the control system allowing the lifting of the mobile assembly 4-5-6, comprises:
  • a first push button 15 movable vertically and housed in a cup 16 called to be fixedly installed in an opening 17 formed in the cover 18 of the tank;
  • a spring 19 acting in compression and tending to push the push-button 15 outwards, that is to say upwards; this spring being for example wedged, by means of its opposite ends, on the one hand, against the lower face 15a of said push-button and, on the other hand, against the bottom 16a of the cup 16;
  • the transmission rod 14 which can be driven in axial translation downwards, by the push button 15, this transmission rod passing longitudinally through the moving assembly 4-5-6;
  • and a lifting member 20 mounted with a pivotability at the lower end of the transmission rod 14 and disposed below the valve 5 and the opercular flange 12a of the shutter; this lifting member is, for example, constituted by a cam or by a small lever of the first type, the oscillation axis 21 of which is carried by a cross member 22 fixedly disposed through the evacuation orifice E of the base 8, below the seat 7 of the valve 5.

Le siège 7 du clapet 5 et le bord supérieur du bras de résistance du levier basculant 20 sont réciproquement positionnés, de façon que lorsque l'équipage mobile 4-5-6 se trouve en position basse d'inactivité, il repose, par l'intermédiaire de la face inférieure dudit clapet, sur le bord de l'orifice de vidange E, tandis que la collerette operculaire 12a se trouve légèrement éloignée de son siège 4a, de manière à réserver un espace entre celle-ci et ledit siège et à ouvrir l'orifice de surverse inférieur A, ladite collerette operculaire reposant sur le bord supérieur dudit bras de résistance du levier basculant 20, comme cela a été expliqué dans le document FR-A-2.658.844.The seat 7 of the valve 5 and the upper edge of the resistance arm of the tilting lever 20 are reciprocally positioned, so that when the moving element 4-5-6 is in the low inactive position, it rests, by the intermediate the underside of said valve, on the edge of the drain orifice E, while the opercular flange 12a is slightly away from its seat 4a, so as to reserve a space between the latter and said seat and at open the lower overflow opening A, said opercular flange resting on the upper edge of said resistance arm of the tilting lever 20, as explained in document FR-A-2,658,844.

La tige de transmission 14 peut être solidaire en translation du bouton-poussoir 15, ou son extrémité supérieure peut être simplement placée au-dessous d'une partie dudit bouton-poussoir de façon à être déplacée axialement vers le bas, lorsqu'on appuie sur ledit bouton-poussoir. Selon l'exemple illustré, le bouton-poussoir 15 comporte un doigt d'entrainement 15b disposé au-dessus de l'extrémité supérieure de la tige 14, au contact ou à très faible distance de ladite extrémité.The transmission rod 14 may be integral in translation with the push-button 15, or its upper end may simply be placed below a part of said push-button so as to be moved axially downwards, when pressing said push button. According to the example illustrated, the push-button 15 comprises a drive finger 15b disposed above the upper end of the rod 14, in contact with or at very short distance from said end.

Le système de commande permettant le déplacement de l'obturateur 12 du flotteur submersible 6, par rapport audit flotteur, comprend :

  • un deuxième bouton-poussoir 23 mobile verticalement et logé dans la coupelle 16,
  • un ressort 24 agissant en compression et tendant à repousser le bouton-poussoir 23 vers l'extérieur, c'est-à-dire vers le haut ; ce ressort étant par exemple calé, par l'intermédiaire de ses extrémités opposées, d'une part, contre la face inférieure 23a dudit bouton-poussoir et, d'autre part, contre le fond 16a de la coupelle 16 ;
  • une tige tubulaire de poussée 25, disposée autour de la tige de transmission 14, et qui peut être entrainée en translation axiale vers le bas, par le bouton-poussoir 23 ; l'extrémité inférieure 25a de cette tige se trouvant disposée au-dessus et à distance du sommet 12b de l'obturateur 12, en position de repos du mécanisme. En outre, cette tige est dimensionnée de manière qu'en position active, elle limite le déplacement ascensionnel de l'obturateur 12, par rapport à celui du flotteur 6.
The control system allowing the movement of the shutter 12 of the submersible float 6, relative to said float, comprises:
  • a second push button 23 movable vertically and housed in the cup 16,
  • a spring 24 acting in compression and tending to push the push-button 23 outwards, that is to say upwards; this spring being for example wedged, by means of its opposite ends, on the one hand, against the lower face 23a of said push button and, on the other hand, against the bottom 16a of the cup 16;
  • a tubular push rod 25, arranged around the transmission rod 14, and which can be driven in axial translation downwards, by the push button 23; the lower end 25a of this rod being disposed above and at a distance from the top 12b of the shutter 12, in the rest position of the mechanism. In addition, this rod is dimensioned so that in the active position, it limits the upward movement of the shutter 12, relative to that of the float 6.

La tige tubulaire de poussée 25 est solidaire en translation du bouton-poussoir 23, auquel elle est, par exemple, assujettie de manière amovible au moyen d'un assemblage du genre rainure et tenon à té. D'autre part, cette tige tubulaire est, de manière avantageuse, réalisée en deux parties assemblées par un filetage 25a, de manière à autoriser un réglage de la longueur de ladite tige.The tubular push rod 25 is integral in translation with the push button 23, to which it is, for example, removably secured by means of an assembly of the groove and tenon type. On the other hand, this tubular rod is advantageously made in two parts assembled by a thread 25a, so as to allow an adjustment of the length of said rod.

Selon une importante caractéristique de l'invention, les boutons-poussoirs sont conformés et disposés de manière que :

  • l'enfoncement du bouton-poussoir 15 n'exerce aucune action sur le bouton-poussoir 23 ;
  • tandis que l'enfoncement du bouton-poussoir 23, provoque automatiquement l'enfoncement du bouton-poussoir 15.
According to an important characteristic of the invention, the push-buttons are shaped and arranged so that:
  • pressing the push button 15 has no action on the push button 23;
  • while pressing the push button 23, automatically pushes the push button 15.

Selon le mode d'exécution illustré aux figures 1 à 5, le bouton-poussoir 23 comporte un doigt 23b disposé au-dessus et pratiquement au contact du doigt 15b du bouton-poussoir 15.According to the embodiment illustrated in FIGS. 1 to 5, the push button 23 includes a finger 23b disposed above and practically in contact with the finger 15b of the push button 15.

Selon une autre disposition caractéristique de l'invention, des moyens sont prévus pour immobiliser momentanément le système de commande de soulèvement de l'équipage mobile 4-5-6 et le système de commande de positionnement de l'obturateur 12, dans leur position d'ouverture.According to another characteristic arrangement of the invention, means are provided for momentarily immobilizing the lifting control system of the moving element 4-5-6 and the positioning control system of the shutter 12, in their position d 'opening.

Selon le mode d'exécution illustré aux figures 1 à 5, ces moyens sont constitués par un agencement complémentaire de la coupelle 16 et du bouton-poussoir 23. Par exemple, la paroi périphérique de la coupelle 16 peut être munie d'une petite dent ou bossage 26 destinée à coopérer avec un cran ou entaille 27 dont est latéralement pourvu le bouton-poussoir 23.According to the embodiment illustrated in Figures 1 to 5, these means are constituted by a complementary arrangement of the cup 16 and the push button 23. For example, the peripheral wall of the cup 16 may be provided with a small tooth or boss 26 intended to cooperate with a notch or notch 27 with which the push button 23 is laterally provided.

Pour permettre de les distinguer l'un de l'autre, les boutons-poussoirs 15 et 23 peuvent avoir une coloration différente, ou comporter, sur leur face supérieure, un repère ou symbole littéral ou graphique permettant de les identifier instantanément.To allow them to be distinguished from one another, the pushbuttons 15 and 23 can have a different coloring, or have, on their face upper, a literal or graphic marker or symbol allowing them to be identified instantly.

On explique ci-après le fonctionnement du mécanisme de chasse à double commande qui vient d'être décrit.The operation of the dual control flushing mechanism which has just been described is explained below.

En période de remplissage ou d'inactivité (figure 1) :

  • l'équipage mobile 4-5-6 est en position basse, le clapet 5 repose sur son siège 7 et obture l'orifice de vidange E ; d'autre part, le bouton-poussoir 15 et la tige de transmission 14 sont en position haute ;
  • la collerette operculaire 12a de l'obturateur 12 est légèrement éloignée de son siège 4a et repose sur le bras de résistance du levier basculant 20 ; d'autre part, le bouton-poussoir 23 et la tige de poussée 25 sont en position haute.
During the busy or inactive period (Figure 1):
  • the moving assembly 4-5-6 is in the low position, the valve 5 rests on its seat 7 and closes the drain orifice E; on the other hand, the push button 15 and the transmission rod 14 are in the high position;
  • the opercular collar 12a of the shutter 12 is slightly away from its seat 4a and rests on the resistance arm of the rocking lever 20; on the other hand, the push button 23 and the push rod 25 are in the high position.

En fin de remplissage, le niveau N 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 4, de sorte que celui-ci peut remplir sa fonction en cas de fermeture défectueuse du robinet d'alimentation. L'eau remplit également les espaces C et D.At the end of filling, the level N of the water contained in the tank is generally located a little below the location where the upper end of the overflow tube 4 is located, so that it can fill its function in the event of faulty closing of the supply valve. Water also fills spaces C and D.

Lorsque l'on souhaite procéder à une vidange complète du réservoir, en appuyant sur le bouton-poussoir 15, on provoque la descente de la tige de transmission 14 et le basculement du levier 20 dont le bras de résistance pivote vers le haut en entrainant, dans un premier temps, le soulèvement de l'obturateur 12 qui ferme l'orifice A et, dans un deuxième temps, le soulèvement du clapet 5 et de l'équipage mobile 4-5-6. L'eau afflue vers l'orifice de vidange E à travers les ouvertures ménagées entre la base de la cloche 3 et la surface supérieure du culot 8 et, en passant sous le flotteur 6, communique un mouvement de remontée supplémentaire à ce dernier dont le déplacement ascendant se trouve arrêté par le sommet 3a de la cloche extérieure 3 contre lequel vient buter la partie supérieure dudit flotteur (figure 4), l'obturateur 12 restant plaqué contre son siège sous l'effet de la pression de l'eau qui ne peut entrer dans le flotteur.When it is desired to carry out a complete emptying of the reservoir, by pressing the push-button 15, the transmission rod 14 is lowered and the lever 20 is tilted, the resistance arm of which pivots upwards, driving, firstly, the lifting of the shutter 12 which closes the orifice A and, secondly, the lifting of the valve 5 and of the moving assembly 4-5-6. The water flows towards the drain orifice E through the openings made between the base of the bell 3 and the upper surface of the base 8 and, passing under the float 6, communicates an additional upward movement to the latter, of which the upward movement is stopped by the top 3a of the outer bell 3 against which the upper part of said float abuts (FIG. 4), the shutter 12 remaining pressed against its seat under the effect of the pressure of the water which cannot enter the float.

Lorsqu'on relâche le bouton-poussoir 15, celui-ci remonte sous l'action du ressort 19, en entraînant un mouvement ascendant correspondant de la tige de transmission 12 si celle-ci se trouve mécaniquement assujettie audit bouton-poussoir, tandis que le levier basculant 20 reprend sa position initiale, ou sans que cela modifie la position de ladite tige et dudit levier, dans le cas contraire.When the push button 15 is released, it goes up under the action of the spring 19, causing a corresponding upward movement of the transmission rod 12 if the latter is mechanically subject to said push button, while the tilting lever 20 returns to its initial position, or without this modifying the position of said rod and of said lever, otherwise.

Lors d'une vidange totale du réservoir, l'équipage mobile 4-5-6 reste en position haute tant que la flottabilité du flotteur 6 demeure assurée ; en fin de vidange, le niveau de l'eau descend progressivement et ledit équipage mobile retombe naturellement dans sa position de repos (figure 1) lorsqu'il n'y a plus d'eau dans le réservoir et que la sustentation du flotteur n'est plus assurée. Le clapet 5 se trouve de nouveau appliqué sur son siège 7 et ferme l'orifice d'évacuation ; d'autre part, la retombée du flotteur entraine le pivotement du levier 20 vers le bas et la remontée de la tige 14, si cette dernière n'est pas assujettie au bouton-poussoir 15.During a complete emptying of the tank, the mobile assembly 4-5-6 remains in the high position as long as the buoyancy of the float 6 remains ensured; at the end of emptying, the water level gradually drops and said mobile assembly naturally falls back into its rest position (FIG. 1) when there is no more water in the tank and the float's lift does not is more assured. The valve 5 is again applied to its seat 7 and closes the discharge orifice; on the other hand, the fall of the float causes the lever 20 to pivot downwards and the rod 14 to rise, if the latter is not subject to the push button 15.

Lorsqu'on désire obtenir une demi-vidange ou vidange partielle du réservoir, on appuie sur le bouton-poussoir 23, ce qui entraine simultanément l'enfoncement du bouton-poussoir 15.When it is desired to obtain a half-emptying or partial emptying of the reservoir, the push-button 23 is pressed, which simultaneously causes the push-button 15 to be pressed.

L'enfoncement du bouton-poussoir 15 assure le soulèvement de l'équipage mobile 4-5-6, comme cela vient d'être expliqué, tandis que l'enfoncement du bouton-poussoir 23 et le déplacement descendant de la tige 25, ont pour conséquence de limiter le mouvement ascendant de l'obturateur 12 par rapport à celui du flotteur 6, de sorte que la collerette operculaire 12a dudit obturateur se trouve éloignée de son siège 4a, ce qui a pour effet d'ouvrir l'orifice inférieur A dudit flotteur (figure 5). Celui-ci se remplit ainsi rapidement d'eau. Durant ce remplissage, les deux systèmes de commande se trouvent immobilisés en position d'ouverture par l'action du dispositif de verrouillage 26-27.The depressing of the push button 15 ensures the lifting of the mobile assembly 4-5-6, as has just been explained, while the depressing of the push button 23 and the downward movement of the rod 25, have as a consequence of limiting movement ascending of the shutter 12 relative to that of the float 6, so that the opercular flange 12a of said shutter is located away from its seat 4a, which has the effect of opening the lower orifice A of said float (FIG. 5) . It quickly fills with water. During this filling, the two control systems are immobilized in the open position by the action of the locking device 26-27.

Lorsque l'eau remplit le flotteur 6, la flottabilité de celui-ci n'est plus assurée, et il retombe sous l'effet de son propre poids, en provoquant, outre la fermeture de l'orifice d'évacuation E et l'interruption de la vidange, le basculement du bras de résistance du levier 20 vers le haut, la remontée de la tige de transmission 14 qui repousse le bouton-poussoir 15 vers le haut, lequel repousse à son tour le bouton-poussoir 23 vers le haut, en provoquant le déverrouillage du dispositif d'immobilisation momentanée 26-27. Le ressort 19 assure ensuite la remontée complète du bouton-poussoir 15, tandis que le ressort 24 assure la remontée complète du bouton-poussoir 23 et celle de la tige de poussée 25. D'autre part, après la retombée du flotteur 6, la collerette operculaire 12a de l'obturateur 12, demeure éloignée de son siège 4a, ce qui maintient l'orifice A en position d'ouverture et permet la vidange du flotteur 6.When the water fills the float 6, the buoyancy of the latter is no longer ensured, and it falls back under the effect of its own weight, causing, in addition to the closure of the discharge orifice E and the interruption of emptying, tilting of the resistance arm of the lever 20 upwards, raising of the transmission rod 14 which pushes the push button 15 upwards, which in turn pushes the push button 23 upwards , by causing the unlocking of the momentary immobilization device 26-27. The spring 19 then ensures the complete ascent of the push button 15, while the spring 24 ensures the complete ascent of the push button 23 and that of the push rod 25. On the other hand, after the fall of the float 6, the opercular flange 12a of the shutter 12, remains distant from its seat 4a, which keeps the orifice A in the open position and allows the emptying of the float 6.

Selon le mode d'exécution illustré aux figures 6 à 11, le bouton-poussoir 15 du système de commande permettant le soulèvement de l'équipage mobile 4-5-6, entraine une tige de transmission disposée verticalement. De manière avantageuse, cette tige de transmission est réalisée en deux parties séparées. La partie ou tige supérieure 28 est assujettie au bouton-poussoir 15 et son extrémité inférieure est munie d'une semelle d'appui discoïdale 29. La partie ou tige inférieure 31 est disposée dans l'alignement de la précédente et son extrémité supérieure est pourvue d'une platine d'entrainement discoïdale 30. En position de repos, la semelle 29 se trouve disposée au-dessus et à très faible distance ou au contact, de la platine 30.According to the embodiment illustrated in FIGS. 6 to 11, the push button 15 of the control system allowing the lifting of the movable assembly 4-5-6, drives a transmission rod arranged vertically. Advantageously, this transmission rod is produced in two separate parts. The upper part or rod 28 is subject to the push button 15 and its lower end is provided with a discoidal support sole 29. The lower part or rod 31 is arranged in alignment with the previous one and its upper end is provided with a discoidal drive plate 30. In the rest position, the sole 29 is located above and at a very short distance or in contact with the plate 30.

Sur la tige inférieure 31 est fixée, au moyen d'une articulation 32, l'une des extrémités d'un levier pivotant 33 fixé, au moyen d'une articulation 34, sur une monture 35 en forme de portique, rigidement solidaire de l'enveloppe extérieure 1 du mécanisme. L'autre extrémité du levier pivotant 33 est reliée, par une articulation 36, à l'extrémité supérieure d'une tige d'entrainement 37. L'extrémité inférieure de cette tige d'entrainement traverse le passage 13 ménagé dans la barrette supérieure 12b de l'obturateur 12, et elle est munie d'un talon de traction 38 emprisonné à l'intérieur du corps dudit obturateur.On the lower rod 31 is fixed, by means of a joint 32, one of the ends of a pivoting lever 33 fixed, by means of a joint 34, on a frame 35 in the form of a gantry, rigidly secured to the 'outer casing 1 of the mechanism. The other end of the pivoting lever 33 is connected, by a hinge 36, to the upper end of a drive rod 37. The lower end of this drive rod passes through the passage 13 formed in the upper bar 12b shutter 12, and it is provided with a traction heel 38 trapped inside the body of said shutter.

D'autre part, le bouton-poussoir 23 du système de commande permettant le déplacement de l'obturateur 12 du flotteur submersible 6, entraine une tige de transmission disposée verticalement. Cette tige de transmission est également, de manière intéressante, exécutée en deux parties séparées. La partie ou tige supérieure 39 est assemblée au bouton-poussoir 23 et son extrémité inférieure est munie d'une semelle d'appui discoïdale 40. D'autre part, la partie ou tige inférieure 42 est disposée dans l'alignement de la précédente et son extrémité supérieure est pourvue d'une platine d'entrainement discoïdale 41.On the other hand, the push button 23 of the control system allowing the movement of the shutter 12 of the submersible float 6, drives a transmission rod arranged vertically. This transmission rod is also, interestingly, executed in two separate parts. The upper part or rod 39 is assembled with the push button 23 and its lower end is provided with a discoidal support sole 40. On the other hand, the lower part or rod 42 is arranged in alignment with the previous one and its upper end is provided with a discoidal drive plate 41.

En position de repos, la semelle 40 se trouve disposée au-dessus et à très faible distance, ou au contact, de la platine d'entrainement 41. Dans cette position, une portion 41a de la périphérie de la tête 41 se trouve placée au-dessus et à très faible distance, ou au contact, d'une partie 30a de la périphérie de la tête 30.In the rest position, the sole 40 is located above and at a very short distance, or in contact, with the drive plate 41. In this position, a portion 41a of the periphery of the head 41 is placed at the -above and at a very short distance, or in contact, with part 30a of the periphery of the head 30.

L'extrémité inférieure de la tige inférieure 42, est assujettie à un bras latéral 43 orienté horizontalement, lequel est, d'autre part, solidaire de la partie supérieure d'une tige tubulaire de poussée 44, disposée autour de la tige d'entrainement 37 ; l'extrémité inférieure 44a de cette tige de poussée se trouvant disposée au-dessus et à distance de la barrette supérieure 12b de l'obturateur 12, en position de repos du mécanisme.The lower end of the lower rod 42 is subject to a horizontally oriented lateral arm 43 which, on the other hand, is integral with the upper part of a tubular push rod 44, disposed around the drive rod 37; the lower end 44a of this push rod being disposed above and at a distance from the upper bar 12b of the shutter 12, in the rest position of the mechanism.

D'autre part, la tige de poussée 44 est dimensionnée de manière qu'en position active, elle limite le déplacement ascensionnel de l'obturateur 12, par rapport au mouvement ascendant du flotteur 6.On the other hand, the push rod 44 is dimensioned so that in the active position, it limits the upward movement of the shutter 12, relative to the upward movement of the float 6.

Selon le mode d'exécution illustré aux figures 6 à 11, les moyens permettant d'immobiliser momentanément le système de commande de soulèvement de l'équipage mobile 4-5-6 et le système de commande de déplacement de l'obturateur 12, dans leur position d'ouverture, sont constitués par un agencement complémentaire du bras latéral 43 et d'une languette verticale 45, orientée vers le bas, dont est munie la monture 35, à sa partie supérieure. Par exemple, la languette 45 peut être munie d'une petite dent ou bossage 46 destinée à coopérer avec un cran ou entaille 47 dont est latéralement pourvu le bras 43.According to the embodiment illustrated in FIGS. 6 to 11, the means making it possible to temporarily immobilize the lifting control system of the moving element 4-5-6 and the movement control system of the shutter 12, in their open position, are constituted by a complementary arrangement of the lateral arm 43 and a vertical tongue 45, oriented downwards, with which the mount 35 is provided, at its upper part. For example, the tongue 45 may be provided with a small tooth or boss 46 intended to cooperate with a notch or notch 47 with which the arm 43 is laterally provided.

Des moyens sont prévus pour assurer le guidage des tiges des deux systèmes de commande.Means are provided for guiding the rods of the two control systems.

Pour les tiges supérieures 28 et 39 , ces moyens sont, par exemple, constitués par des petits puits 48, 49 dont est muni le fond de la coupelle 16 et dans lesquels peuvent coulisser des manchons 50 et 51 rattachés à la face inférieure des boutons-poussoirs 15 et 23, et dans lesquels est engagée l'extrémité supérieure desdites tiges supérieures 28 et 29, respectivement.For the upper rods 28 and 39, these means are, for example, constituted by small wells 48, 49 with which the bottom of the cup 16 is provided and in which sleeves 50 and 51 can slide, attached to the underside of the buttons. pushers 15 and 23, and in which is engaged the upper end of said upper rods 28 and 29, respectively.

Les tiges inférieures 31, 42 sont guidées par des passages à axes verticaux 52, 53, respectivement, ménagés à la partie supérieure de la monture 35.The lower rods 31, 42 are guided by passages with vertical axes 52, 53, respectively, formed at the upper part of the frame 35.

L'extrémité supérieure de la tige d'actionnement 44 est guidée dans un collier à axe vertical 54 que présente la partie supérieure de ladite monture.The upper end of the actuating rod 44 is guided in a collar with a vertical axis 54 presented by the upper part of said frame.

Les tiges de transmission 28-31 et 39-42 sont fixées de manière réglable aux organes auxquels elles sont rattachées. Dans ce but, les tiges de transmission supérieures 28 et 39 sont assemblées par vissage aux manchons 50, 51 des boutons-poussoirs 15, 23, respectivement. D'autre part, la tige de transmission inférieure 31 est assemblée, par vissage, à un écrou 56 qui porte l'axe d'articulation 32 du levier 33, tandis que la tige de transmission inférieure 42 comporte un filetage par l'intermédiaire duquel elle est fixée dans un taraudage à axe vertical dont est muni le bras 43.The transmission rods 28-31 and 39-42 are fixed in an adjustable manner to the members to which they are attached. For this purpose, the upper transmission rods 28 and 39 are assembled by screwing to the sleeves 50, 51 of the push buttons 15, 23, respectively. On the other hand, the lower transmission rod 31 is assembled, by screwing, to a nut 56 which carries the hinge pin 32 of the lever 33, while the lower transmission rod 42 has a thread through which it is fixed in a thread with a vertical axis with which the arm 43 is provided.

Le fontionnement de ce mécanisme de chasse à double commande est le suivant :The operation of this dual control flushing mechanism is as follows:

En période de remplissage ou d'inactivité (figure 6) :

  • l'équipage mobile 4-5-6 est en position basse, le clapet 5 repose sur son siège 7 et obture l'orifice de vidange E ; d'autre part, le bouton-poussoir 15, la tige supérieure 28 et la tige inférieure 31 sont en position haute, tandis que la tige d'actionnement 37 est en position basse ;
  • la collerette operculaire 12a de l'obturateur 12 est légèrement éloignée de son siège 4a, ledit obturateur se trouvant suspendu à la tige 37 ;
  • le bouton-poussoir 23, la tige supérieure 39, la tige inférieure 42 et la tige d'actionnement 44, sont en position haute, l'extrémité inférieure 44a de ladite tige d'actionnement étant disposée à distance de la barrette ou paroi supérieure ajourée 12b de l'obturateur 12.
During the busy or inactive period (Figure 6):
  • the moving assembly 4-5-6 is in the low position, the valve 5 rests on its seat 7 and closes the drain orifice E; on the other hand, the push button 15, the upper rod 28 and the lower rod 31 are in the high position, while the actuating rod 37 is in the low position;
  • the opercular collar 12a of the shutter 12 is slightly away from its seat 4a, said shutter being suspended from the rod 37;
  • the push button 23, the upper rod 39, the lower rod 42 and the actuation rod 44 are in the high position, the lower end 44a of said actuation rod being disposed at a distance from the perforated bar or upper wall Shutter 12b 12.

Lorsqu'on souhaite procéder à une vidange complète du réservoir, on appuie sur le bouton-poussoir 15, ce qui provoque la descente de la tige supérieure 28 et de la tige inférieure 31, le basculement du levier pivotant 33 et le déplacement axial ascendant de la tige d'actionnement 37 laquelle, par l'intermédiaire de son talon 38, exerce un effort de traction sur la barrette supérieure 12b de l'obturateur 12 qui , par l'intermédiaire de sa collerette operculaire 12a assure le soulèvement de l'équipage mobile 4-5-6 permettant l'évacuation de l'eau contenue dans le réservoir (figure 9).When it is desired to carry out a complete emptying of the reservoir, the push-button 15 is pressed, which causes the upper rod 28 and the lower rod 31 to descend, the pivoting lever 33 to tilt and the upward axial displacement of the actuating rod 37 which, by means of its heel 38, exerts a tensile force on the upper bar 12b of the shutter 12 which, by means of its opercular flange 12a ensures the lifting of the crew mobile 4-5-6 allowing the evacuation of the water contained in the tank (figure 9).

Lorsqu'on relâche le bouton-poussoir 15, celui-ci remonte sous l'action du ressort 19, sans que cela ait une influence quelconque sur les autres organes du mécanisme de commande.When the push-button 15 is released, it goes up under the action of the spring 19, without this having any influence on the other members of the control mechanism.

Lors d'une vidange totale du réservoir, l'équipage mobile 4-5-6 reste en position haute tant que la flottabilité du flotteur 6 reste assurée ; en fin de vidange, le niveau de l'eau descend progressivement et ledit équipage mobile retombe naturellement dans sa position de repos (figure 6) lorsqu'il n'y a plus d'eau dans le réservoir et que la sustentation du flotteur n'est plus assurée. La retombée de l'équipage mobile provoque un mouvement axial descendant de la tige d'actionnement 37, le basculement en sens inverse du levier pivotant 33 et la remontée de la tige inférieure 31 dont la platine 30 vient se replacer juste au-dessous ou au contact de la semelle 29 de la tige supérieure 28.During a complete emptying of the tank, the mobile assembly 4-5-6 remains in the high position as long as the buoyancy of the float 6 remains ensured; at the end of emptying, the water level gradually drops and said mobile assembly naturally falls back into its rest position (FIG. 6) when there is no more water in the tank and the float's lift does not is more assured. The fallout of the movable assembly causes an axial movement descending from the actuating rod 37, the tilting in the opposite direction of the pivoting lever 33 and the ascent of the lower rod 31 whose plate 30 comes to be replaced just below or at contact of the sole 29 of the upper rod 28.

Lorsqu'on désire obtenir une demi-vidange ou vidange partielle du réservoir, on appuie sur le bouton-poussoir 23, ce qui provoque (figure 10) la descente de la tige supérieure 39 laquelle entraine simultanément : d'une part, la descente de la tige inférieure 42 et, d'autre part, la descente de la tige inférieure 31 laquelle se trouve en effet entrainée vers le bas par l'appui exercé sur sa tête 30, par la tête 41 de la tige 42.When it is desired to obtain a half-emptying or partial emptying of the reservoir, the push-button 23 is pressed, which causes (FIG. 10) the descent of the upper rod 39 which simultaneously causes: on the one hand, the descent of the lower rod 42 and, on the other hand, the descent of the rod lower 31 which is in fact driven downwards by the support exerted on its head 30, by the head 41 of the rod 42.

Le déplacement axial descendant de la tige inférieure 31 entraine, comme indiqué précédemment, le soulèvement de l'équipage mobile 4-5-6.The downward axial movement of the lower rod 31 causes, as indicated above, the lifting of the mobile assembly 4-5-6.

D'autre part, la descente de la tige inférieure 42 entraine un mouvement axial descendant de la tige tubulaire 44 lequel a pour effet de limiter le mouvement axial ascendant de l'obturateur 12 par rapport à celui du flotteur 6, de sorte que la collerette operculaire 12a dudit obturateur se trouve éloignée de son siège 4a, ce qui a pour effet d'ouvrir l'orifice inférieur A dudit flotteur. Celui-ci se remplit ainsi rapidement d'eau. Pendant ce remplissage, les deux systèmes de commande se trouvent immobilisés en position d'ouverture par l'action du dispositif de verrouillage 46-47.On the other hand, the descent of the lower rod 42 causes an axial downward movement of the tubular rod 44 which has the effect of limiting the upward axial movement of the shutter 12 relative to that of the float 6, so that the flange opercular 12a of said shutter is remote from its seat 4a, which has the effect of opening the lower orifice A of said float. It quickly fills with water. During this filling, the two control systems are immobilized in the open position by the action of the locking device 46-47.

Lorsque l'eau remplit le flotteur 6, la flottabilité de celui-ci n'est plus assurée et il retombe sous l'effet de son poids et de son lest, en assurant la fermeture de l'orifice d'évacuation E et l'interruption de la vidange. La retombée de l'équipage mobile 4-5-6 entraine, comme indiqué précédemment, un mouvement axial descendant de la tige d'actionnement 37, le basculement en sens inverse du levier 33 et la remontée de la tige de transmission inférieure 31. D'autre part, la remontée de la tige de transmission inférieure 31 assure également la remontée de la tige de transmission inférieure 42, la tête 41 de cette dernière se trouvant, en effet, poussée vers le haut par le bord sous-jacent de la tête 30 de la première ; la force de cette poussée étant nettement supérieure à la force de retenue exercée par les moyens de verrouillage 46-47, ces derniers se trouvent neutralisés (voir détail de la figure 11), et la remontée de la tige de transmission inférieure 42 entraine un mouvement axial ascendant de la tige tubulaire d'actionnement 44 dont elle est solidaire.When the water fills the float 6, the buoyancy of the latter is no longer ensured and it falls back under the effect of its weight and its ballast, ensuring the closure of the evacuation orifice E and the emptying interruption. The fallout of the moving assembly 4-5-6 causes, as indicated previously, an axial movement descending from the actuating rod 37, the tilting in the opposite direction of the lever 33 and the raising of the lower transmission rod 31. D on the other hand, the ascent of the lower transmission rod 31 also ensures the ascent of the lower transmission rod 42, the head 41 of the latter being, in fact, pushed upwards by the underlying edge of the head 30 of the first; the force of this thrust being clearly greater than the retaining force exerted by the locking means 46-47, the latter are neutralized (see detail in FIG. 11), and the rising of the lower transmission rod 42 causes an upward axial movement of the tubular actuating rod 44 of which it is integral.

Lorsqu'on relâche le bouton-poussoir 23, immédiatement après l'avoir enfoncé, celui-ci remonte sous l'action du ressort 24, sans que cela ait une influence quelconque sur la position des autres organes du système de double commande.When the push button 23 is released, immediately after being pressed, it rises under the action of the spring 24, without this having any influence on the position of the other members of the dual control system.

On observe que grâce à l'absence de liaison mécanique entre les tiges de transmission supérieures 28, 39 et les tiges de transmission inférieures 31, 42, respectivement, on peut appuyer sur l'un ou l'autre des boutons-poussoirs 15 et 23, sans que cela ait une influence sur la position des autres organes du système de double commande et sur le déroulement du processus de chasse, comme on le voit mieux sur la figure 11. Les volumes d'eau évacués sont constants et la vidange ne peut être interrompue lorsqu'on a actionné le bouton-poussoir 23.It is observed that due to the absence of mechanical connection between the upper transmission rods 28, 39 and the lower transmission rods 31, 42, respectively, one can press one or the other of the push buttons 15 and 23 , without this having an influence on the position of the other organs of the dual control system and on the course of the flushing process, as can be seen better in FIG. 11. The volumes of water evacuated are constant and the emptying cannot be interrupted when push button 23 has been pressed.

Le flotteur 6, l'obturateur 12 et le passage annulaire A ménagé entre le corps dudit obturateur et le bord de l'ouverture inférieure du tube de surverse, sont dimensionnés de manière que le remplissage dudit flotteur et sa retombée après que l'on ait ouvert ledit passage, s'opèrent dans un temps correspondant à une vidange de la moitié du volume d'eau disponible contenu dans le réservoir.The float 6, the shutter 12 and the annular passage A formed between the body of said shutter and the edge of the lower opening of the overflow tube, are dimensioned so that the filling of said float and its fallout after having open said passage, take place in a time corresponding to the emptying of half the volume of available water contained in the tank.
