Description

La présente invention concerne un mécanisme de chasse à flotteur et à commande axiale par bouton-poussoir, pour réservoir de chasse d'eau de cabinet d'aisances.The present invention relates to a float flushing mechanism and axially controlled by a push button, for a toilet flush tank.

Plus précisément, l'invention concerne un dispositif de chasse du genre décrit dans le document FR-A-2.580.694 et comportant un clapet destiné à s'appliquer sur le bord de l'orifice de vidange ménagé dans le fond du réservoir de chasse d'eau, ce clapet étant monté à l'extrémité inférieure ou à la partie inférieure d'une tige tubulaire 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 ; au-dessus du clapet, est disposé un flotteur par exempte constitué par la partie inférieure renflée de ladite tige ; ce dispositif comprenant encore, de préférence, une enveloppe extérieure comportant une partie inférieure renflée ou cloche extérieure destinée à être installée fixement dans ledit réservoir et dans laquelle est logé avec une aptitude de mouvement axial, le flotteur intérieur.More specifically, the invention relates to a flushing device of the kind described in document FR-A-2,580,694 and comprising a valve intended to be applied on the edge of the drain orifice formed in the bottom of the flushing tank. of water, this valve being mounted at the lower end or at the lower part of a tubular rod 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; above the valve, there is disposed a float, for example, constituted by the swollen lower part of said rod; this device also preferably comprising an outer casing comprising a bulged lower part or outer bell intended to be fixedly installed in said tank and in which is housed with an axial movement ability, the inner float.

Les mécanismes de ce genre sont de conception simple et ils fonctionnent de manière très satisfaisante. En outre, leurs parties composantes n'étant pas soumises à des efforts importants, elles peuvent être exécutées de façon très économique en toute matière plastique rigide adéquate.Mechanisms like this are simple in design and work very satisfactorily. In addition, their component parts not being subjected to significant efforts, they can be executed very economically in any suitable rigid plastic material.

Le soulèvement de l'ensemble ou équipage mobile clapet-tube de surverse-flotteur, c'est-à-dire l'ouverture de l'oririce de vidange ou d'évacuation du réservoir de chasse, est obtenu au moyen d'un dispositif à bouton de traction ou à bouton-poussoir, ce dernier présentant l'avantage d'être moins exposé à l'arrachement accidentel ou malveillant et de pouvoir être plus facilement agencé de manière à assurer son inviolabilité.The lifting of the valve or float-float tube or mobile assembly, that is to say the opening of the drain or evacuation orifice of the flushing tank, is obtained by means of a pull button or push button device, the latter having the advantage of being less exposed to accidental or malicious tearing and of being able to be more easily arranged so as to ensure its inviolability.

Des mécanismes de chasse commandés par bouton-poussoir à déplacement vertical sont, par exemple, décrits dans les documents EP-A-0.124.458, EP-A-0.128.847, FR-A-2.591.250 et FR-A-2.580.694.Hunting mechanisms controlled by push-button with vertical displacement are, for example, described in documents EP-A-0.124.458, EP-A-0.128.847, FR-A-2.591.250 and FR-A-2.580 .694.

Selon ces mécanismes, lorsqu'on a appuyé sur le bouton-poussoir de commande et amorcé le processus de rinçage, ce processus ne peut plus être interrompu et le clapet ne retombe sur son siège qu'après la vidange complète du réservoir. Un tel résultat souvent souhaitable peut aussi constituer un inconvénient lorsqu'une quantité d'eau sensiblement inférieure à la capacité du réservoir serait suffisante pour obtenir un bon rinçage de la cuvette. Il en résulte donc une utilisation de quantités excessives d'eau regrettable aussi bien pour l'utilisateur que pour la collectivité.According to these mechanisms, when the control push-button has been pressed and the flushing process has started, this process cannot be interrupted any more and the valve does not fall back into its seat until the tank has been completely emptied. Such an often desirable result can also constitute a drawback when an amount of water substantially less than the capacity of the tank is sufficient to obtain a good rinsing of the bowl. This therefore results in the use of excessive amounts of water which is regrettable both for the user and for the community.

On a cherché (FR-A-2.548.328) à pallier à cet inconvénient par un dispositif d'actionnement de la soupage d'écoulement, comportant un bouton-poussoir de commande à déplacement vertical, solidaire d'un organe de poussée pouvant coulisser axialement et pivoter latéralement de façon limitée, de part et d'autre de son axe de coulissement, de manière à agir sur l'un ou l'autre des bras d'un levier basculant, l'un des bras de ce levier étant relié, par l'intermédiaire d'organes de transmission, à la soupape d'écoulement, de sorte que selon que l'organe de poussée appuie sur l'un ou l'autre des bras du levier pivotant, on exerce une action de traction ascendante entraînant le soulèvement de ladite soupape ou une action de poussée descendante provoquant l'abaissement de cette dernière en direction de son siège.Attempts have been made (FR-A-2,548,328) to overcome this drawback by a device for actuating the flow valve, comprising a control push-button with vertical displacement, integral with a pushing member capable of sliding. axially and pivot laterally in a limited way, on either side of its sliding axis, so as to act on one or the other of the arms of a tilting lever, one of the arms of this lever being connected , via transmission members, to the flow valve, so that depending on whether the pushing member presses on one or the other of the arms of the pivoting lever, an upward pulling action is exerted causing the lifting of said valve or a downward pushing action causing the lowering of the latter in the direction of its seat.

Ce dispositif permettant d'interrompre la vidange, a pour inconvénient de nécessiter l'utilisation d'un nombre de pièces relativement important pour assurer la liaison mécanique entre le bouton-poussoir de commande et la soupape d'écoulement, ce qui complique la construction des mécanismes de chasse et influe défavorablement sur leur prix de revient. D'autre part, ces pièces de liaison mécanique travaillent avec des mouvements différents (mouvements longitudinaux, mouvements circulaires, ou combinaison de ces deux mouvements, et avec d'importants efforts et frottements, ce qui favorise leur coincement et le blocage du mécanisme.This device making it possible to interrupt the emptying, has the disadvantage of requiring the use of a relatively large number of parts to ensure the mechanical connection between the control push-button and the flow valve, which complicates the construction of the hunting mechanisms and adversely affects their cost price. On the other hand, these mechanical connection parts work with different movements (longitudinal movements, circular movements, or combination of these two movements, and with significant forces and friction, which promotes their jamming and blocking of the mechanism.

L'invention a notamment pour but de remédier à ces inconvénients, par la réalisation d'un mécanisme de chasse extrêmement simple, lequel met en oeuvre, de manière préférée, un dispositif de commande à bouton-poussoir à déplacement vertical du genre décrit dans le document FR-A-2.591.250 et grâce auquel il n'existe aucune liaison mécanique entre la tige tubulaire portant le clapet et l'organe de soulèvement de celui-ci, de sorte que les mouvements de ces parties composantes mobiles du mécanisme de chasse, ne peuvent se contrarier mutuellement.The object of the invention is in particular to remedy these drawbacks, by producing an extremely simple flushing mechanism, which preferably uses a push-button control device with vertical displacement of the kind described in the document FR-A-2.591.250 and thanks to which there is no mechanical connection between the tubular rod carrying the valve and the lifting member thereof, so that the movements of these movable component parts of the flushing mechanism , cannot contradict each other.

Selon l'invention, cet objectif est atteint grâce à un mécanisme de chasse du genre précédemment évoqué, à commande par bouton-poussoir, ce mécanisme de chasse étant principalement remarquable en ce que le flotteur est équipé 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, sous la poussée de l'organe de soulèvement du clapet et sous la pression de l'eau s'évacuant du réservoir, ou éloigné dudit siège sous l'impulsion d'un organe de poussée solidaire de la tige de transmission, de façon à permettre une entrée d'eau dans ledit flotteur entraînant la retombée de celui-ci et l'interruption du processus de chasse.According to the invention, this objective is achieved by means of a flushing mechanism of the kind mentioned above, controlled by a push button, this flushing mechanism being mainly remarkable in that the float is equipped 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, under the thrust of the valve lifting member and under the pressure of the water evacuating from the tank, or away from said seat under the impulse of a thrust member secured to the transmission rod, so as to allow entry of water into said float causing the fall of the latter and the interruption of the hunting process.

Comme cela est expliqué dans la suite du présent exposé, ce mécanisme de chasse permet d'interrompre, à volonté, la vidange du réservoir de chasse, lorsqu'on estime que le lavage ou rinçage de la cuvette se trouve réalisé avant que la totalité de l'eau contenu dans ledit réservoir n'ait été évacuée, c'est-à-dire avant l'achèvement du processus normal de chasse. En outre, ce mécanisme de chasse est extrêmement simple, de sorte qu'il peut être fabriqué de manière très économique, en toutes matières plastiques appropriées, tandis que tous ses organes mobiles se déplacent coaxialement, sans frottement ou avec des frottements très faibles, c'est-à-dire dans des conditions favorisant un fonctionnement bon et durable.As explained in the remainder of this description, this flushing mechanism makes it possible to interrupt, at will, the emptying of the flushing tank, when it is estimated that the washing or rinsing of the bowl is carried out before all of the the water contained in said tank has not been removed, that is to say before the completion of the normal flushing process. In addition, this flushing mechanism is extremely simple, so that it can be manufactured very economically, in all suitable plastics, while all of its movable members move coaxially, without friction or with very low friction, c that is to say in conditions favoring a good and lasting operation.

On se reporte auxdits dessins pour décrire un exemple de réalisation avantageux, mais non limitatif, du mécanisme de chasse à commande par bouton-poussoir et à flotteur submersible selon l'invention.Reference is made to said drawings to describe an advantageous, but not limiting, embodiment of the flushing mechanism controlled by a push button and with a submersible float according to the invention.

Ce mécanisme de chasse comprend, de façon connue, une enveloppe extérieure désignée dans son ensemble par la référence 1 et comportant une portion supérieure cylindrique ou tube-allonge vertical 2 et une portion inférieure renflée ou cloche extérieure 3, également cylindrique et dont le diamètre est nettement supérieur à celui dudit tube-allonge ; cette enveloppe extérieure étant destinée à être installée fixement dans le réservoir de chasse, comme cela est décrit dans la suite du présent exposé.This flushing mechanism comprises, in known manner, an outer envelope designated as a whole by the reference 1 and comprising a cylindrical upper portion or vertical extension tube 2 and a bulged lower portion or external bell 3, also cylindrical and whose diameter is significantly higher than that of said extension tube; this outer envelope being intended to be fixedly installed in the flushing 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 D et un orifice supérieur E, de manière à permettre une décharge automatique d'un éventuel trop plein qui pourrait 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 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 D.In the outer casing 1, is housed, with a capacity for axial upward or downward movement, a "overflow" tube 4 comprising a lower orifice D and an upper orifice E, so as to allow automatic discharge of any excess that could result from the faulty closing of the valve controlling the admission of water to 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 the opening D.

La portion inférieure du tube de surverse est 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 au clapet 5.The lower portion of the overflow tube is 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 it is located. the upper face of the valve 5.

Le flotteur 6 est logé, concentriquement, dans la cloche extérieure 3 et un espace ou passage annulaire A 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 A 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, et un passage annulaire B est 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, and an annular passage B is formed between the cylindrical side walls of said tube and said upper portion .

Le dispositif de chasse comprend également un système de commande à bouton-poussoir qui peut être avantageusement du genre de celui qui est illustré dans le document FR-A-2.591.250. Ce système de commande permettant le soulèvement du clapet 5, comprend :

  • un bouton-poussoir 7, mobile axialement et verticalement, ce bouton-poussoir étant logé dans une coupelle 8 appelée à être installée fixement dans le trou 9 que présente le couvercle 10 des réservoirs de chasse pour le passage de la tige des dispositifs de commande ; cette coupelle 8 est, par exemple, solidaire d'une tige tubulaire (non représentée) dotée d'un filetage extérieur par l'intermédiaire duquel elle est vissée dans l'écrou constitué par le chapeau formant le sommet de l'enveloppe extérieure 1 ;
  • un ressort 11 agissant en compression et tendant à repousser le bouton-poussoir 7 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 dudit bouton-poussoir et, d'autre part, contre le fond de la coupelle 8 ;
  • une tige axiale de transmission 12 solidaire en translation axiale du bouton-poussoir 7 et qui peut être reliée à celui-ci par l'intermédiaire de son extrémité supérieure ; cette tige de transmission traversant longitudinalement l'équipage mobile 4-5-6 ;
  • et un organe de soulèvement 13 monté avec une aptitude de pivotement à l'extrémité inférieure de la tige de transmission 12 et disposé au-dessous du clapet 5 ; cet organe est, par exemple constitué par une came ou par un petit levier du premier type dont l'axe d'oscillation est porté par une traverse 14 disposée fixement à travers l'orifice d'évacuation du culot décrit ci-après, au-dessous du siège du clapet.
The flushing device also includes a push-button control system which can advantageously be of the type illustrated in document FR-A-2,591,250. This control system allowing the valve 5 to be raised, comprises:
  • a push button 7, axially and vertically movable, this push button being housed in a cup 8 called to be fixedly installed in the hole 9 presented by the cover 10 of the flush tanks for the passage of the rod of the control devices; this cup 8 is, for example, integral a tubular rod (not shown) with an external thread through which it is screwed into the nut formed by the cap forming the top of the outer casing 1;
  • a spring 11 acting in compression and tending to push the push-button 7 outwards, that is to say upwards; this spring being for example wedged, by means of its opposite ends, on the one hand, against the underside of said push button and, on the other hand, against the bottom of the cup 8;
  • an axial transmission rod 12 integral in axial translation with the push-button 7 and which can be connected to the latter via its upper end; this transmission rod passing longitudinally through the moving assembly 4-5-6;
  • and a lifting member 13 mounted with a pivotability at the lower end of the transmission rod 12 and arranged below the valve 5; this member is, for example constituted by a cam or by a small lever of the first type, the oscillation axis of which is carried by a cross-member 14 fixedly disposed through the evacuation orifice of the base described below, au- below the valve seat.

Ce culot désigné, dans son ensemble, par la référence 15, comporte un orifice central C dont le bord circulaire supérieur 16 constitue le siège du clapet 5.This base, designated as a whole by the reference 15, comprises a central orifice C, the upper circular edge 16 of which constitutes the seat of the valve 5.

Lorsque le mécansime de chasse est positionné à l'intérieur d'un réservoir de chasse lui-même fixé sur une cuvette de cabinet d'aisances, le culot 15 est installé fixement, au moyen d'un écrou (non représenté) se vissant sur la portion cylindrique inférieure filetée 15a dudit culot, dans l'orifice 17 que présente le fond 18 du réservoir (partiellement représenté aux figures 1 à 5). De la sorte, l'orifice central C du culot 15 constitue l'orifice de vidange dudit réservoir. L'étanchéité entre le fonds 18 du réservoir et l'assise ou face d'appui du culot 15, est réalisée au moyen d'un joint annulaire intermédiaire 19 exécuté en caoutchouc ou autre matériau adéquat.When the hunting mechanism is positioned inside a hunting tank itself fixed on a toilet bowl, the base 15 is installed fixedly, by means of a nut (not shown) screwed onto the threaded lower cylindrical portion 15a of said base, in the orifice 17 that has the bottom 18 of the tank (partially shown in Figures 1 to 5). In this way, the central opening C of the base 15 constitutes the emptying orifice of said tank. The seal between the bottom 18 of the tank and the seat or bearing face of the base 15 is achieved by means of an intermediate annular seal 19 made of rubber or other suitable material.

La base de la cloche extérieure 3 et le culot 15 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 15 est, par exemple, pourvu de trois fourchettes de guidage et de verrouillage 20 espacées de 120 degrés et entre les branches desquelles est engagée et retenue la base de la cloche extérieure 3, les branches internes 20a de ces fourchettes de verrouillage 20 et le collier 20b auquel elles sont rattachées par leur sommet étant pourvus de nervures verticales 20c servant de guides au flotteur 6, lors des mouvements verticaux de celui-ci.The base of the outer bell 3 and the base 15 are arranged in a complementary manner or provided with complementary joining means making it possible to rigidly assemble them, in a removable manner, while allowing the passage of water between said base and said base. The base 15 is, for example, provided with three guide and locking forks 20 spaced 120 degrees and between the branches of which the base of the outer bell 3 is engaged and retained, the internal branches 20a of these locking forks 20 and the collar 20b to which they are attached by their top being provided with vertical ribs 20c serving as guides for the float 6, during the vertical movements of the latter.

Selon l'invention, le flotteur est équipé d'un obturateur 21 mobile axialement et verticalement et pouvant être plaqué contre son siège constitué par le bord de l'orifice inférieur D du tube de surverse 4, sous la poussée de l'organe basculant 13 permettant le soulèvement du clapet 5 ou sous la pression de l'eau s'évacuant du réservoir, en assurant ainsi la flottabilité dudit flotteur. D'autre part, la tige de transmission 12 est munie d'un organe de poussée 22 permettant l'abaissement de l'obturateur 21 et l'ouverture de l'orifice inférieur D, lorsque le flotteur 6 se trouve en position soulevée de flottaison, de manière à permettre une entrée d'eau dans ledit flotteur entrainant la submersion de ce dernier et la retombée du clapet 5 sur son siège 16.According to the invention, the float is equipped with a shutter 21 movable axially and vertically and which can be pressed against its seat constituted by the edge of the lower orifice D of the overflow tube 4, under the thrust of the tilting member 13 allowing the valve 5 to be raised or under the pressure of the water discharging from the tank, thus ensuring the buoyancy of said float. On the other hand, the transmission rod 12 is provided with a thrust member 22 allowing the shutter 21 to be lowered and the lower orifice D to be opened, when the float 6 is in the raised buoyancy position , so as to allow water to enter said float, causing it to submerge and the valve 5 to fall back onto its seat 16.

L'organe de poussée 22 est, par exemple, constitué par une bague calée sur la tige de transmission 12, dans la portion basse de celle-ci.The pushing member 22 is, for example, constituted by a ring wedged on the transmission rod 12, in the lower portion of it.

L'obturateur 21 comporte avantageusement un corps tubulaire 23, de préférence cylindrique, dont le sommet est fermé par une paroi supérieure 24 dans laquelle est ménagé un trou 25 pour le passage de la tige de transmission 12. A sa base, le corps tubulaire 23 est muni d'une collerette operculaire 26 constituant une soupape dont le siège est constitué par la face inférieure de la monture 4a du clapet 5 délimitant l'ouverture inférieure D du tube de surverse 4. Cette soupape 26 peut être formée d'une seule pièce avec ledit corps tubulaire.The shutter 21 advantageously comprises a tubular body 23, preferably cylindrical, the top of which is closed by an upper wall 24 in which is formed a hole 25 for the passage of the transmission rod 12. At its base, the tubular body 23 is provided with an opercular flange 26 constituting a valve whose seat is formed by the lower face of the mounting 4a of the valve 5 delimiting the lower opening D of the overflow tube 4. This valve 26 can be formed in one piece with said tubular body.

Intérieurement, le corps 23 de l'obturateur 21 comporte au moins une et, de préférence, deux cloisons verticales 27, parallèles divisant l'espace intérieur du corps en plusieurs chambres, par exemple en trois chambres 28, 29, 30. La chambre intermédiaire 29 comporte le trou 25 de passage de la tige de transmission 12, tandis que les deux chambres latérales 28 et 30 de volume égal et disposées symétriquement de chaque côté de la chambre 29, sont fermées de manière étanche à leur sommet par la paroi 24 et constituent ainsi des poches d'air améliorant la flottabilité de l'obturateur 21 et du flotteur 6.Internally, the body 23 of the shutter 21 comprises at least one and, preferably, two vertical partitions 27, parallel dividing the interior space of the body into several chambers, for example into three chambers 28, 29, 30. The intermediate chamber 29 includes the hole 25 for the passage of the transmission rod 12, while the two lateral chambers 28 and 30 of equal volume and arranged symmetrically on each side of the chamber 29 are closed in leaktight manner at their top by the wall 24 and thus constitute air pockets improving the buoyancy of the shutter 21 and of the float 6.

D'autre part, le corps 23 est pourvu, extérieurement et latéralement, d'ailettes de butées 31 disposées à distance de la collerette operculaire 26. Ces ailettes de butée sont logées dans le flotteur 6 et, lorsque l'obturateur 21 est éloigné de son siège, elles viennent buter contre le bord interne de l'orifice D (figure 5). Lorsque l'équipage mobile se trouve en position haute, en cours de vidange, du fait de sa flottabilité, et que l'on appuie sur le bouton-poussoir pour interrompre la vidange, la présence des ailettes de butée limite la course de descente de l'obturateur 21, et le mouvement de l'eau qui afflue vers l'orifice de vidange C agit sur la face supérieure de la collerette operculaire 26 et contribue à accélérer le mouvement de retombée de l'équipage mobile et la fermeture dudit orifice.On the other hand, the body 23 is provided, externally and laterally, with abutment fins 31 arranged at a distance from the opercular flange 26. These abutment fins are housed in the float 6 and, when the shutter 21 is distant from its seat, they abut against the internal edge of the orifice D (Figure 5). When the moving element is in the high position, during emptying, due to its buoyancy, and when the push-button is pressed to interrupt the emptying, the presence of the stop fins limits the descent stroke of the shutter 21, and the movement of the water which flows towards the emptying orifice C acts on the upper face of the opercular flange 26 and contributes to accelerating the fall-back movement of the mobile assembly and the closing of said orifice.

Le siège 16 du clapet 5 et le bord supérieur du bras de résistance 13a du levier basculant 13 sont réciproquement positionnés, de façon que lorsque l'équipage mobile constitué par le tube de surverse 4, le flotteur 6 et le clapet 5 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 C, tandis que la collerette operculaire 26 se trouve légèrement éloignée de son siège 4a, de manière à réserver un espace F entre celle-ci et ledit siège et à ouvrir l'orifice de surverse inférieur D, ladite collerette operculaire reposant sur le bord supérieur dudit bras de résitance 13a du levier basculant 13, cette disposition étant plus spécialement représentée à la figure 6.The seat 16 of the valve 5 and the upper edge of the resistance arm 13a of the rocking lever 13 are reciprocally positioned, so that when the movable assembly consisting of the overflow tube 4, the float 6 and the valve 5 is in position low inactivity, it rests, via the underside of said valve, on the edge of the drain orifice C, while the opercular flange 26 is slightly away from its seat 4a, so as to reserve a space F between the latter and said seat and to open the lower overflow orifice D, said opercular flange resting on the upper edge of said resistance arm 13a of the rocking lever 13, this arrangement being more particularly shown in FIG. 6.

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

En période de remplissage ou d'inactivité (figure 1), l'équipage mobile 4-5-6 du mécanisme est en position basse, le clapet 5 repose sur son siège et obture l'orifice de vidange C ; d'autre part, le bouton-poussoir de commande 7 et la bague de poussée 22 sont en position haute. 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, et celui-ci peut remplir sa fonction en cas de fermeture défectueuse du robinet d'alimentation. L'eau remplit également les espaces A et B.During the filling or inactivity period (FIG. 1), the mobile assembly 4-5-6 of the mechanism is in the low position, the valve 5 rests on its seat and closes the drain orifice C; on the other hand, the control push button 7 and the push ring 22 are in the high position. At the end of filling, the level N of the water contained in the tank is generally a little below the location where the upper end of the overflow tube 4 is located, and this can fulfill its function by faulty closing of the supply valve. Water also fills spaces A and B.

En appuyant sur le bouton-poussoir 7, on provoque la descente de la tige de transmission 12 et le basculement du levier 13 dont le bras de résistance 13a pivote vers le haut en entrainant, dans un premier temps, le soulèvement de l'obturateur 21 qui ferme l'orifice D 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 C à travers les ouvertures 32 ménagées entre la base de la cloche 3 et la surface supérieure du culot 15 et, en passant sous le flotteur 6, communique un mouvement de remontée supplémentaire audit flotteur dont le déplacement ascendant se trouve arrêté par la bague de poussée 22 contre laquelle vient buter le sommet 24 de l'obturateur 21 (figure 2), ce dernier restant plaqué contre son siège sous l'effet de la pression de l'eau qui ne peut entrer dans le flotteur.By pressing the push-button 7, the transmission rod 12 is lowered and the lever 13 is tilted, including the resistance arm 13a pivots upwardly causing, firstly, the lifting of the shutter 21 which closes the orifice D and, secondly, the lifting of the valve 5 and of the moving element 4-5-6. The water flows towards the drain orifice C through the openings 32 formed between the base of the bell 3 and the upper surface of the base 15 and, passing under the float 6, communicates an additional upward movement to said float, the upward movement is stopped by the thrust ring 22 against which abuts the top 24 of the shutter 21 (Figure 2), the latter remaining pressed against its seat under the effect of the pressure of the water which cannot enter in the float.

Lorsqu'on relâche le bouton-poussoir 7, celui-ci remonte sous l'action du ressort 11, en entraînant un mouvement ascendant correspondant de la tige de transmission 12 et de la bague de poussée 22, tandis que le levier basculant 13 reprend sa position initiale (figure 3). Le flotteur 4 et son obturateur 21 accompagnent la tige 12 et la bague de poussée 22 dans leur mouvement ascendant.When the push button 7 is released, it rises under the action of the spring 11, causing a corresponding upward movement of the transmission rod 12 and of the push ring 22, while the rocking lever 13 resumes its initial position (figure 3). The float 4 and its shutter 21 accompany the rod 12 and the thrust ring 22 in their upward movement.

Lors d'une vidange totale du réservoir, l'équipage mobile 4-5-6 reste en position haute tant que la flottabilité du flotteur reste assurée ; en fin de vidange, le niveau de l'eau descend progressivement et ledit équipage mobile 4-5-6 retombe naturellement dans sa position de repos (figure 1) lorsqu'il n'y a plus d'eau dans le réservoir et que la sustentatin du flotteur 6 n'est plus assurée.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 remains ensured; at the end of emptying, the water level gradually decreases and said moving assembly 4-5-6 naturally falls back into its rest position (FIG. 1) when there is no more water in the tank and the float 6 sustentatin is no longer guaranteed.

Lorsqu'on veut interrompre la vidange alors que le niveau N' de l'eau se trouve à une hauteur intermédiaire quelconque, on appuie sur le bouton-poussoir 7, ce qui entraîne la descente de la tige de transmission 12 et de la bague de poussée 22 laquelle appui sur le sommet 24 de l'obturateur 21 qui se trouve déplacé vers le bas (figure 4) ; la collerette operculaire se trouve éloignée de son siège et l'orifice inférieur D du flotteur étant ouvert, celui-ci se remplit d'eau ; après que l'on ait relaché le bouton-poussoir (figure 5), l'équipage mobile 4-5-6 retombe et le clapet 5 vient reposer sur son siège en interrompant totalement l'écoulement (on se retrouve alors dans la position illustrée à la figure 1).When it is desired to interrupt the emptying while the level N 'of the water is at any intermediate height, the push-button 7 is pressed, which causes the transmission rod 12 and the ring to descend. thrust 22 which rests on the top 24 of the shutter 21 which is moved down (Figure 4); the opercular flange is far from its seat and the lower orifice D of the float being open, the latter fills with water; after the push button has been released (Figure 5), the moving assembly 4-5-6 falls back down and the valve 5 comes to rest on its seat, completely interrupting the flow (we are then in the position illustrated in Figure 1).

Cette opération peut être répétée plusieurs fois au cours d'une même vidange et cela à n'importe quel moment.This operation can be repeated several times during the same drain and this at any time.
