Description

La présente invention a pour objet un dispositif de décharge d'un réservoir de chasse d'eau d'un lieu d'aisance comprenant un cylindre vertical destiné à être fixé par sa base sur une ouverture d'évacuation d'eau de la paroi de fond du réservoir, un siège de soupape dans le cylindre au-dessus de cette ouverture d'évacuation d'eau, des ouvertures d'admission d'eau sur la périphérie du cylindre au-dessus du siège de soupape, une soupape de décharge mobile par coulissement vertical dans le cylindre au-dessus de son siège avec une tige de soupape creuse débouchant sous la soupape par sa partie basse et au-dessus du cylindre par sa partie haute, un palier de guidage de la tige de soupape à la partie haute du cylindre et un moyen de liaison de l'ensemble mobile tige-soupape à une commande de soulèvement temporaire.The present invention relates to a device for discharging a toilet tank of a place of comfort comprising a vertical cylinder intended to be fixed by its base on a water discharge opening of the wall of tank bottom, a valve seat in the cylinder above this water discharge opening, water intake openings on the periphery of the cylinder above the valve seat, a movable relief valve by vertical sliding in the cylinder above its seat with a hollow valve stem opening under the valve by its lower part and above the cylinder by its upper part, a guide bearing from the valve rod to the upper part of the cylinder and a means of connecting the movable rod-valve assembly to a temporary lifting control.

Dans les dispositifs connus de ce type, auxquels se rapporte l'invention, un semi-automatisme est prévu pour que l'actionnement de la commande de soulèvement de la soupape de décharge libère la totalité de l'eau contenue dans le réservoir, quelle que soit la brièveté de cet actionnement.In known devices of this type, to which the invention relates, a semi-automatic mechanism is provided so that the actuation of the lifting control of the relief valve releases all of the water contained in the tank, whatever or the brevity of this actuation.

Ce semi-automatisme, des plus simples, est obtenu par association d'un flotteur à la tige de soupape, dans le cylindre, au-dessus et à une distance suffisante de la soupape pour que son effet soit annulé par la pression de l'eau de remplissage sur la face supérieure de la soupape, lorsque cette eau submerge le flotteur en question.This semi-automatic system, very simple, is obtained by associating a float to the valve stem, in the cylinder, above and at a sufficient distance from the valve so that its effect is canceled out by the pressure of the filling water on the upper face of the valve, when this water submerges the float in question.

Après soulèvement de la soupape, l'action de ce flotteur, libérée, maintient celle-ci relevée jusqu'à écoulement quasi complet de l'eau contenue dans le réservoir, après quoi l'ensemble mobile tige-soupape, avec son flotteur, retombe par gravité, la soupape venant reposer sur son siège.After lifting the valve, the action of this float, released, keeps it raised until flow almost complete with the water contained in the tank, after which the movable rod-valve assembly, with its float, falls by gravity, the valve coming to rest on its seat.

Par ailleurs, le déclenchement et l'arrêt de l'alimentation d'eau du réservoir sont commandés par un flotteur de contrôle de niveau, de manière habituelle, dès la vidange effectuée et la retombée de la soupape sur son siège.Furthermore, the triggering and stopping of the supply of water to the tank is controlled by a level control float, in the usual way, as soon as the emptying is carried out and the valve falls back onto its seat.

A l'heure de l'écologie, il apparaît évident que ce système, qui libère la totalité de l'eau contenue dans le réservoir à chaque actionnement de la commande de soulèvement de la soupape de décharge, est générateur d'un gaspillage d'eau qui n'est plus tolérable, par le fait qu'il dépasse souvent de beaucoup les besoins de rinçage de la cuvette d'aisance.At the time of the ecology, it appears obvious that this system, which releases all the water contained in the tank with each actuation of the control of lifting of the relief valve, generates a waste of water that is no longer tolerable, by the fact that it often greatly exceeds the flushing needs of the toilet bowl.

Il existe bien un système de rinçage de la cuvette d'aisance, qui n'est cependant plus utilisé dans l'habitat moderne, qui permettrait de régler la quantité d'eau stictement nécessaire aux besoins; il s'agit là de chasses d'eau dans lesquelles l'eau de rinçage provient directement du réseau public d'alimentation en eau sous pression, dont l'utilisateur peut contrôler le débit et la durée à l'aide d'un simple robinet. Cependant, avec ce système, le fait de pouvoir laisser le robinet ouvert pour faire autre chose avant de le refermer après rinçage, présente un risque de dépassement du besoin par oubli temporaire, voire même total, de le refermer.There is indeed a system for rinsing the toilet bowl, which is however no longer used in modern homes, which would make it possible to regulate the amount of water stictly necessary for the needs; these are flushes in which the rinsing water comes directly from the public pressurized water supply network, the user of which can control the flow and duration with a simple tap . However, with this system, being able to leave the tap open to do something else before closing it after rinsing, presents a risk of exceeding the need by temporary, or even total, forgetfulness to close it.

L'invention a pour but de permettre un contrôle efficace de la quantité d'eau de rinçage utilisée, en conformité avec les besoins minimaux, à l'aide d'un dispositif du genre décrit en début d'exposé, et ceci sans présenter le risque de dépassement inhérent au système précité de contrôle par un robinet.The object of the invention is to allow effective control of the amount of rinse water used, in accordance with the minimum requirements, using a device of the type described at the start of the description, and this without presenting the risk of overshooting inherent in the aforementioned system of control by a tap.

A cet effet, le dispositif selon l'invention est caractérisé en ce qu'il comporte un moyen de poussée pour conférer à l'ensemble mobile tige-soupape une capacité de poussée verticale vers le bas supérieure à la composante verticale, dirigée vers le haut, de la pression de l'eau contenue dans le réservoir sur ledit ensemble mobile lorsque la soupape est soulevée de son siège.To this end, the device according to the invention is characterized in that it includes a pushing means for giving the movable rod-valve assembly a vertical downward pushing capacity greater than the vertical component, directed upwards. , of the pressure of the water contained in the tank on said movable assembly when the valve is lifted from its seat.

De la sorte, dès l'instant que la commande de soulèvement de la soupape est relâchée par l'utilisateur, la soupape est repoussée vers le bas sur son siège et l'eau cesse de s'écouler.In this way, as soon as the valve lift control is released by the user, the valve is pushed back down onto its seat and the water stops flowing.

La quantité d'eau de rinçage utilisée est ainsi fonction du temps d'actionnement de la commande de soulèvement de la soupape, ce qui permet à l'utilisateur de régler aisément cette quantité en fonction du besoin.The amount of rinse water used is thus a function of the actuation time of the valve lift control, which allows the user to easily adjust this amount according to need.

Il n'y a pas de risques de dépassement de la quantité d'eau de rinçage jugée nécessaire par l'utilisateur puisque le seul geste de relâchement de la commande suffit à arrêter l'écoulement de l'eau.There is no risk of exceeding the amount of rinse water deemed necessary by the user since the simple act of releasing the control is enough to stop the flow of water.

Le moyen de pression associé à l'ensemble mobile tigesoupape peut être constitué de la manière la plus simple par le choix de son poids propre, auquel cas la vitesse de réponse du rappel vers le bas de la soupape, au relâchement de la commande, est fonction de la grandeur de l'excédent de poids de cet ensemble mobile par rapport à la poussée opposée de la pression de l'eau sur lui; lorsque cet excédent de poids n'est pas jugé suffisant, il peut être complété par l'adjonction d'un lest audit ensemble.The pressure means associated with the movable valve stem assembly can be made in the simplest way by choosing its own weight, in which case the speed of response of the return to the bottom of the valve, when the control is released, is function of the magnitude of the excess weight of this movable assembly relative to the opposite thrust of the water pressure on it; when this excess weight is not considered sufficient, it may be supplemented by adding a ballast to the said assembly.

Ce moyen de pression peut aussi être complété par un ressort de compression, interposé par exemple entre la soupape et le palier de guidage de la tige de soupape. Dans ce cas, et comme il est décrit et montré dans la description qui suit et le dessin qui lui est associé, il est possible, moyennant une simple appropriation, de permettre à l'utilisateur de moduler lui-même à la fois la vitesse de réponse du rappel de la soupape et le débit de l'eau évacuée.This pressure means can also be supplemented by a compression spring, interposed for example between the valve and the guide bearing of the valve stem. In this case, and as described and shown in the description which follows and the drawing which is associated with it, it is possible, by means of a simple appropriation, to allow the user to modulate himself both the speed of response from the valve reminder and the flow rate of the drained water.

Le dessin annexé représente, à titre d'exemples, deux formes d'exécution de l'objet de l'invention.The accompanying drawing shows, by way of example, two embodiments of the subject of the invention.

La figure 1 de ce dessin est une vue d'ensemble en demi-coupe axiale de la première forme d'exécution.Figure 1 of this drawing is an overall view in axial half-section of the first embodiment.

La figure 2 est une vue partielle en demi-coupe axiale de la seconde forme d'exécution.Figure 2 is a partial view in axial half-section of the second embodiment.

Le dispositif selon ces deux formes d'exécution est représenté sur ces deux figures en position abaissée de fermeture de la soupape de décharge.The device according to these two embodiments is shown in these two figures in the lowered closed position of the relief valve.

Dans sa première forme d'exécution représentée figure 1, ce dispositif se compose d'un cylindre 1 vertical fixé par sa base sur une ouverture d'évacuation d'eau de la paroi de fond 2 d'un réservoir de chasse d'eau, d'une soupape de décharge 3 avec sa tige 4, d'un ressort à boudin de compression 5, d'un couvercle de cylindre 6 et d'un palier 7 de guidage de la tige de soupape 4.In its first embodiment shown in FIG. 1, this device consists of a vertical cylinder 1 fixed by its base on a water discharge opening from the bottom wall 2 of a flush tank, a relief valve 3 with its rod 4, a compression coil spring 5, a cylinder cover 6 and a bearing 7 for guiding the valve rod 4.

Dans cet assemblage :

  • Le cylindre 1 comporte à sa base un manchon fileté 8 suivi d'une collerette d'appui 9 qui est serrée, avec un joint d'étanchéité 10 et par un écrou 11, sur la paroi de fond 2, un siège de soupape à paroi tronconique 12 au-dessus du niveau de l'ouverture de cette paroi de fond, quatre ouvertures rectangulaires d'admission d'eau 13 équiangulairement espacées sur sa périphérie et au-dessus du siège de soupape 12 ainsi que deux autres ouvertures circulaires 14 situées au-dessus des premières et destinées à faciliter l'évacuation/l'admission d'eau dans la partie haute du cylindre 1.
  • La soupape 3, en forme de couronne à base tronconique surmontée d'un manchon, comporte un joint torique 15 engagé dans une rainure de sa paroi tronconique venant porter contre la paroi tronconique correspondante du siège de soupape 12. La tige de soupape 4, constituée par un tube cylindrique fixé dans la soupape 3, débouche sous celle-ci par son extrémité inférieure et au-dessus du cylindre et de son palier de guidage 7 par son extrémité supérieure 16; un collier à pontet à fixation 17 est fixé à cette extrémité pour liaison avec une commande de soulèvement de la soupape 3 qui est ici constituée par un bouton 18 de levage manuel muni d'une tige 19 passant par un trou 20 du couvercle 21 du réservoir et qui est vissée dans le pontet 17.
  • Le couvercle 6 se compose d'un collier 21 de fixation à la paroi du cylindre 1 suivi d'un manchon 22 à filetage intérieur formant écrou.
  • Le palier 7 de guidage de la tige de soupape 4 est constitué par une vis tubulaire dont le filetage 23 est en prise dans le filetage intérieur du couvercle 6. Ce palier 7 présente à sa partie haute un volant de manoeuvre 24 et à sa face inférieure une rainure circulaire 25 d'appui et de centrage du ressort à boudin 5, et un manchon 26 constituant une contre-butée réglable en hauteur par manipulation du volant 24.
  • Le ressort à boudin de compression 5, concentrique à la tige de soupape 4, est interposé entre la contrebutée 26 du palier 7 et une butée 27 fixée sur cette tige au-dessus de la soupape 3 et des ouvertures 13 du cylindre 1, cette butée comportant à sa base un collier présentant une rainure 28 d'appui et de centrage du ressort 5 semblable à la rainure 25 du palier 7.
In this assembly:
  • The cylinder 1 has at its base a threaded sleeve 8 followed by a support flange 9 which is tightened, with a seal 10 and by a nut 11, on the bottom wall 2, a valve seat with a frustoconical wall 12 above the level of the opening of this bottom wall, four rectangular water inlet openings 13 equiangularly spaced on its periphery and above the seat valve 12 and two other circular openings 14 located above the first and intended to facilitate the evacuation / admission of water into the upper part of the cylinder 1.
  • The valve 3, in the form of a crown with a frustoconical base surmounted by a sleeve, comprises an O-ring 15 engaged in a groove in its frustoconical wall coming to bear against the corresponding frustoconical wall of the valve seat 12. The valve stem 4, constituted by a cylindrical tube fixed in the valve 3, opens under the latter by its lower end and above the cylinder and its guide bearing 7 by its upper end 16; a clamping collar with fixing 17 is fixed at this end for connection with a lifting control of the valve 3 which is here constituted by a manual lifting button 18 provided with a rod 19 passing through a hole 20 of the cover 21 of the tank and which is screwed into the trigger guard 17.
  • The cover 6 consists of a collar 21 for fixing to the wall of the cylinder 1 followed by a sleeve 22 with an internal thread forming a nut.
  • The bearing 7 for guiding the valve stem 4 is constituted by a tubular screw whose thread 23 is engaged in the internal thread of the cover 6. This bearing 7 has at its upper part a handwheel 24 and at its lower face a circular groove 25 for supporting and centering the coil spring 5, and a sleeve 26 constituting a counter-stop adjustable in height by manipulation of the handwheel 24.
  • The compression coil spring 5, concentric with the valve rod 4, is interposed between the abutment 26 of the bearing 7 and a stop 27 fixed on this rod above the valve 3 and the openings 13 of the cylinder 1, this stop comprising at its base a collar having a groove 28 for supporting and centering the spring 5 similar to the groove 25 in the bearing 7.

La distance C entre la butée 27 et la contre-butée 26 délimite la course en hauteur de l'ensemble mobile tige 4-soupape 3. Cette course est ici, dans sa valeur maximale représentée sur cette figure, prévue de telle sorte que lorsque la soupape 3 est entièrement relevée, butée contre contre-butée, les ouvertures 13 d'admission d'eau dans le cylindre 1 sont entièrement dégagées sur toute leur hauteur, le débit de l'eau de rinçage évacuée étant alors à sa valeur maximale.The distance C between the stop 27 and the counter stop 26 defines the height stroke of the movable rod 4-valve assembly 3. This stroke is here, in its maximum value represented in this figure, provided so that when the valve 3 is fully raised, abutment against abutment, the openings 13 for admitting water into the cylinder 1 are completely cleared over their entire height, the flow rate of the rinsing water discharged then being at its maximum value.

La pression du ressort de compression 5, en position représentée d'extension maximale, est prévue de telle sorte que, par sommation au poids propre de l'ensemble mobile tige 4-soupape 3, il confère à cet ensemble une capacité de poussée vers le bas supérieure à la composante verticale, dirigée vers le haut, de la pression de l'eau du réservoir sur ledit ensemble lorsque la soupape est relevée de son siège.The pressure of the compression spring 5, in the position shown for maximum extension, is provided such that, by summation of the dead weight of the movable rod 4-valve assembly 3, it gives this assembly a thrust capacity towards the bottom greater than the vertical component, directed upwards, of the pressure of the water in the reservoir on said assembly when the valve is lifted from its seat.

La longueur libre D de vissage du palier 7 dans le couvercle 6 du cylindre, avant la rencontre de ce dernier par le volant de manoeuvre 24, est prévue, dans la position de course C maximale représentée, inférieure à cette course C, de manière qu'il reste toujours un minimum de hauteur dégagée des ouvertures 13 d'admission d'eau dans le cylindre à fin de course du vissage du palier 7 par le volant 24 lorsque la soupape 3 est entièrement relevée.The free length D of screwing the bearing 7 into the cover 6 of the cylinder, before the latter meets the handwheel 24, is provided, in the position of maximum travel C shown, less than this travel C, so that 'There is always a minimum of height cleared from the water intake openings 13 in the cylinder at the end of the screwing of the bearing 7 by the handwheel 24 when the valve 3 is fully raised.

De la sorte l'utilisateur peut, par vissage ou dévissage du palier 7, régler à la fois la pression du ressort 5, qui conditionne pour une bonne part la vitesse de réponse de fermeture de la soupape, et le débit de l'eau de rinçage évacuée, ces deux grandeurs ainsi réglables permettant de moduler avec une efficacité accrue le dosage de la quantité d'eau de rinçage utilisée.In this way the user can, by screwing or unscrewing the bearing 7, adjust both the pressure of the spring 5, which largely determines the response speed of closing the valve, and the flow of water from rinsing evacuated, these two sizes thus adjustable allowing to modulate with an increased efficiency the dosage of the quantity of rinsing water used.

Cependant, cet avantage supplémentaire inhérent à l'emploi d'un ressort à pression réglable n'est pas indispensable au vu du but de l'invention.However, this additional advantage inherent in the use of an adjustable pressure spring is not essential in view of the object of the invention.

Un système non réglable, dans lequel le ressort 5 est directement mis en appui sous et contre le couvercle 7 est parfaitement admissible dans une conception simplifiée et économique.A non-adjustable system, in which the spring 5 is directly supported under and against the cover 7 is perfectly acceptable in a simplified and economical design.

Les formes des structures et le type de commande de soulèvement de la soupape représentés ne sont évidemment pas limitatifs.The shapes of the structures and the type of valve lift control shown are obviously not limiting.

Ainsi les ouvertures 14 de la partie haute du cylindre 1 ne sont pas indispensables lorsque par exemple à fin de course de remontée de la soupape 3, il reste encore au-dessus de son niveau une partie dégagée des ouvertures 13 d'admission d'eau, ou bien lorsque le diamètre extérieur de la soupape est suffisamment plus petit que le diamètre intérieur du cylindre 1.Thus, the openings 14 in the upper part of the cylinder 1 are not essential when, for example at the end of the valve lift stroke 3, there remains still above its level a part which is clear of the water intake openings 13 , or when the outside diameter of the valve is sufficiently smaller than the inside diameter of cylinder 1.

La commande de soulèvement de la soupape, qui sort du cadre de l'invention, peut être de tout autre type, comme par exemple une commande à levier latéral ou une commande au pied pneumatique ou hydraulique.The valve lifting control, which goes beyond the scope of the invention, can be of any other type, such as for example a lateral lever control or a pneumatic or hydraulic foot control.

L'utilisation d'un ressort, qui est avantageuse lors de l'emploi de matériau de faible densité pour la réalisation du dispositif, comme par exemple certaines matières plastiques moulables, peut ne pas être nécessaire et remplacée par le poids propre de l'ensemble mobile tige-soupape lorsque le seul poids propre de cet ensemble dépasse d'une quantité suffisante la poussée opposée de l'eau pour assurer une vitesse de réponse acceptable du rappel vers le bas de la soupape, au relâchement de la commande de soulèvement de celle-ci.The use of a spring, which is advantageous when using low density material for the production of the device, such as certain materials moldable plastics, may not be necessary and replaced by the self-weight of the movable stem-valve assembly when the sole self-weight of this assembly exceeds by sufficient quantity the opposite thrust of the water to ensure an acceptable response speed from the downward return of the valve, to the release of the valve lift control.

Il est également possible, lorsque le seul poids propre de cet ensemble mobile ne suffit pas à assurer une vitesse de réponse suffisamment rapide du rappel vers le bas de la soupape, de lui adjoindre un lest.It is also possible, when the self-weight of this mobile assembly is not sufficient to ensure a sufficiently rapid response speed of the return to the bottom of the valve, to add a ballast to it.

La seconde forme d'exécution représentée figure 2 illustre cette possibilité.The second embodiment shown in Figure 2 illustrates this possibility.

Sur cette figure 2, les éléments inchangés portent les mêmes repères que sur la figure 1, et l'on se réfèrera à la description de la première forme d'exécution en ce qui les concerne.In this FIG. 2, the unchanged elements bear the same references as in FIG. 1, and reference will be made to the description of the first embodiment as far as they are concerned.

Sur la tige de soupape 4 est ici installé un lest métallique 29 en forme d'anneau de section droite rectangulaire inclus dans un boîtier en deux parties semblables 30 de forme cylindrique surmontées chacune d'un manchon 31, le tout étant enfilé autour de la tige de soupape et fixé sur celle-ci, par exemple par collage, à un niveau défini par la course C choisie, au montage de l'ensemble.On the valve stem 4 is installed here a metal ballast 29 in the form of a ring of rectangular cross section included in a housing in two similar parts 30 of cylindrical shape each surmounted by a sleeve 31, the whole being threaded around the stem valve and fixed thereon, for example by gluing, at a level defined by the stroke C chosen, assembly of the assembly.

Le couvercle 70 du cylindre 1 présente ici un simple trou central 32 formant palier de guidage de la tige de soupape 4, et sa paroi intérieure 33 constitue la butée de limitation du déplacement vers le haut de la soupape.The cover 70 of the cylinder 1 has here a simple central hole 32 forming a guide bearing for the valve stem 4, and its inner wall 33 constitutes the stop for limiting the upward movement of the valve.

Ce couvercle 70 est ici représenté amovible par le moyen d'un système de fixation rapide à baïonnettes 34 engageables dans des rainures en L de retenue 35 de la paroi du cylindre 1.This cover 70 is here represented removable by the by means of a quick bayonet fastening system 34 which can be engaged in L-shaped grooves 35 for retaining the wall of the cylinder 1.

Des ouvertures 36 dans la paroi de la partie haute du cylindre 1 et des trous 37 dans le couvercle 70 sont prévues pour faciliter l'évacuation/l'admission de l'eau dans cette partie haute lors des déplacements de l'ensemble mobile tige-soupape.Openings 36 in the wall of the upper part of the cylinder 1 and holes 37 in the cover 70 are provided to facilitate the evacuation / admission of water into this upper part during movement of the movable rod assembly. valve.

En variante, le lest métallique inclus dans le boîtier peut être remplacé par d'autres matériaux, par exemple de la grenaille de plomb, enrobée ou non de matière plastique du genre des résines polymérisables à froid telles que le polyester ou époxyde.As a variant, the metallic ballast included in the housing can be replaced by other materials, for example lead shot, coated or not with plastic material of the kind of cold-polymerizable resins such as polyester or epoxy.

Dans cette forme d'exécution relativement simple, il est également possible de régler le débit d'évacuation de l'eau de rinçage en fixant le boîtier 30-31 non pas par collage sur la tige de soupape 4 mais par serrage à l'aide de vis radiales montées en prise dans des trous filetés des manchons 31 de ce support. Le réglage peut alors se faire après enlèvement du couvercle 70 et remontée de l'ensemble mobile jusqu'à dégager le boîtier 30-31 hors du cylindre 1. Pour faciliter ce réglage, la tige de soupape 4 peut présenter des repères de niveaux.In this relatively simple embodiment, it is also possible to adjust the discharge rate of the rinsing water by fixing the housing 30-31 not by gluing on the valve stem 4 but by tightening using radial screws mounted in threaded holes in the sleeves 31 of this support. The adjustment can then be made after removal of the cover 70 and reassembly of the mobile assembly until the housing 30-31 is released from the cylinder 1. To facilitate this adjustment, the valve stem 4 may have level marks.

Bien entendu, les formes des structures ne sont pas limitatives et ce qui a déjà été dit à ce sujet pour la première forme d'exécution est également valable ici.Of course, the shapes of the structures are not limiting and what has already been said on this subject for the first embodiment is also valid here.

Enfin il est possible, avec un boîtier 30-31 fixé de manière définitive à la tige de soupape 4, de régler le débit de l'eau de rinçage de la même manière que dans la première forme d'exécution, par le moyen d'un palier-butée réglable en hauteur par vissage dans le couvercle du cylindre.Finally it is possible, with a housing 30-31 permanently fixed to the valve stem 4, to adjust the flow rate of the rinsing water in the same way as in the first embodiment, by means of a thrust bearing adjustable in height by screwing into the cylinder cover.
