Description

la présente invention est relative à une soupape destinée à être montée sur une batterie étanche. the present invention relates to a valve intended to be mounted on a sealed battery.

Comme toute batterie, dans une batterie étanche il se produit un léger dégagement gazeux qu'il faut évacuer sans laisser pénétrer l'oxygène de l'air extérieur. Like any battery, in a sealed battery there is a slight release of gas which must be evacuated without allowing oxygen to enter the outside air.

Habituellement, l'homme du métier connaît des soupapes qui ne donnent pas pleinement satisfaction : soit que l'étanchéité à l'air extérieur n'est pas totalement garantie, soit que leur mode de fixation, sur le bac constituant l'enceinte de la batterie, n'est pas satisfaisant. Usually, a person skilled in the art knows valves which are not fully satisfactory: either that the airtightness to the outside air is not completely guaranteed, or that their method of fixing, to the tank constituting the enclosure of the battery, is not satisfactory.

Aussi la présente invention a-t-elle notamment pour but de fournir une soupape pour batterie étanche qui permet de pallier ces inconvénients de l'art antérieur. The object of the present invention is therefore to provide a sealed battery valve which overcomes these drawbacks of the prior art.

Un autre but de l'invention est de fournir une telle soupape qui peut être montée sur tout type de batterie étanche. Another object of the invention is to provide such a valve which can be mounted on any type of sealed battery.

Ces buts, ainsi que d'autres qui apparaîtront par la suite, sont atteints par une soupape pour batterie étanche qui est caractérisée, selon la présente invention, par le fait qu'elle est constituée par une tige creuse comportant, en premier lieu, à une extrémité dite extrémité inférieure, qui est ouverte, un filetage, en deuxième lieu, une collerette pourvue d'un logement circulaire sur sa face inférieure en regard du filetage, et, en troisième lieu, à son extrémité supérieure qui est fermée, une rainure circulaire munie d'une bague élastique et comportant dans son fond une rigole circulaire, au moins un canal reliant cette rigole et l'intérieur de la tige creuse. These aims, as well as others which will appear subsequently, are achieved by a valve for a sealed battery which is characterized, according to the present invention, by the fact that it is constituted by a hollow rod comprising, firstly, at an end called the lower end, which is open, a thread, secondly, a flange provided with a circular housing on its lower face opposite the thread, and, thirdly, at its upper end which is closed, a groove circular provided with an elastic ring and comprising at its bottom a circular channel, at least one channel connecting this channel and the interior of the hollow rod.

Avantageusement, la rigole circulaire est située sensiblement au milieu du fond de la rainure circulaire. Advantageously, the circular channel is located substantially in the middle of the bottom of the circular groove.

De préférence, la collerette est située sensiblement au milieu de la tige creuse. Preferably, the collar is located substantially in the middle of the hollow rod.

Avantageusement, dans le logement circulaire est situé un joint d'étanchéité tel qu'un joint torique. Advantageously, in the circular housing is located a seal such as an O-ring.

Selon une variante de réalisation, entre le haut du filetage et la collerette, la tige creuse comporte une saignée circulaire munie d'un joint torique.  According to an alternative embodiment, between the top of the thread and the flange, the hollow rod has a circular groove provided with an O-ring.

De préférence, la hauteur de la bague élastique est au plus égale à la largeur de la rainure circulaire. La tige creuse comporte deux canaux diamétralement opposés débouchant dans la rigole afin d'évacuer les dégagements gazeux. Preferably, the height of the elastic ring is at most equal to the width of the circular groove. The hollow rod has two diametrically opposite channels opening into the channel in order to evacuate the gas emissions.

Avantageusement, entre la rainure et la collerette est situé un épaulement ayant la forme d'un polygone régulier tel qu'un hexagone, pour l'adaptation d'un moyen de vissage. Advantageously, between the groove and the flange is located a shoulder having the shape of a regular polygon such as a hexagon, for the adaptation of a screwing means.

La description qui va suivre et qui ne présente aucun caractère limitatif, doit être lue en regard de la figure unique annexée qui représente, en coupe longitudinale, une soupape pour batterie étanche selon la présente invention. The description which follows and which has no limiting character, should be read with reference to the single appended figure which represents, in longitudinal section, a valve for a sealed battery according to the present invention.

Comme représenté sur cette figure, une soupape pour batterie étanche est constituée, selon la présente invention, par une tige creuse désignée dans son ensemble par la référence 1. As shown in this figure, a sealed battery valve is constituted, according to the present invention, by a hollow rod generally designated by the reference 1.

A son extrémité inférieure qui est ouverte, cette tige 1 comporte un filetage 2 permettant de visser cette soupape dans la paroi d'un bac constituant un ou plusieurs éléments d'une batterie étanche. At its lower end which is open, this rod 1 has a thread 2 making it possible to screw this valve into the wall of a tank constituting one or more elements of a sealed battery.

Sensiblement en son milieu, cette tige creuse 1 comporte une collerette 3 pourvue sur sa partie inférieure, c'est-à-dire celle dirigée vers le filetage 2, d'un logement circulaire 4. Dans ce logement, est situé un joint torique 5 permettant d'assurer une parfaite étanchéité entre la soupape et la paroi dans laquelle elle est vissée. Significantly in the middle, this hollow rod 1 has a flange 3 provided on its lower part, that is to say that directed towards the thread 2, with a circular housing 4. In this housing, is located an O-ring 5 to ensure a perfect seal between the valve and the wall in which it is screwed.

A son extrémité supérieure, qui est fermée, cette soupape comporte une rainure circulaire 6, dans le fond de laquelle est située, sensiblement à mi-hauteur, une rigole circulaire 12. Dans cette rigole débouchent deux canaux 7, qui sont diamétralement opposés permettant de mettre en communication l'intérieur de la tige creuse 1 avec l'intérieur de la batterie et l'atmosphère extérieure. At its upper end, which is closed, this valve has a circular groove 6, in the bottom of which is located, substantially at mid-height, a circular channel 12. In this channel open two channels 7, which are diametrically opposed allowing to to put in communication the interior of the hollow rod 1 with the interior of the battery and the external atmosphere.

Les gaz présents dans la batterie peuvent ainsi s'échapper.The gases present in the battery can thus escape.

Afin que l'air ambiant ne puisse pénétrer dans la tige creuse 1, cette rainure 6 est munie d'une bague élastique 8 dont la hauteur est au plus égale à la largeur de la rainure 6. So that the ambient air cannot penetrate into the hollow rod 1, this groove 6 is provided with an elastic ring 8 whose height is at most equal to the width of the groove 6.

Lorsqu'un dégagement gazeux se produit à l'inté rieur d'une batterie étanche comprenant une soupape selon la présente invention, les gaz s'échappent par l'intérieur de la tige creuse 1 et par les canaux 7 pour s'accumuler dans la rigole circulaire 12. Ces gaz créent une surpression uniforme tendant à repousser la bague élastique 8 : ils peuvent ainsi s'échapper dans l'atmosphère. Lorsque la surpression a disparu, suite à l'évacuation du dégagement gazeux, la bague élastique 8 reprend sa position de repos dans laquelle elle délimite la rigole circulaire 12. When a gas evolution occurs inside a sealed battery comprising a valve according to the present invention, the gases escape through the interior of the hollow rod 1 and through the channels 7 to accumulate in the circular channel 12. These gases create a uniform overpressure tending to repel the elastic ring 8: they can thus escape into the atmosphere. When the overpressure has disappeared, following the evacuation of the gaseous release, the elastic ring 8 resumes its rest position in which it delimits the circular channel 12.

Entre la rainure 6 et la collerette 3, est situé un épaulement 9 ayant la forme d'un polygone régulier tel qu'un hexagone : cet épaulement 9 permet l'adaptation d'un moyen pour visser cette soupape, telle que par exemple une clef à douille. Le sommet de la soupape peut également comporter une rainure pour le vissage. Between the groove 6 and the flange 3, is located a shoulder 9 having the shape of a regular polygon such as a hexagon: this shoulder 9 allows the adaptation of a means for screwing this valve, such as for example a key with socket. The top of the valve may also have a groove for screwing.

Selon une variante de réalisation, entre le haut du filetage 2 et la face inférieure de la collerette 3 est ménagée une saignée circulaire 10 dans la tige creuse 1 : dans cette saignée 10 peut être disposé un joint torique 11 contribuant à l'étanchéité de la paroi dans laquelle est disposée cette soupape. According to an alternative embodiment, between the top of the thread 2 and the underside of the collar 3 is formed a circular groove 10 in the hollow rod 1: in this groove 10 can be disposed an O-ring 11 contributing to the sealing of the wall in which this valve is arranged.

Les joints toriques 5 et 11 peuvent être réalisés en tout matériau permettant de réaliser une étanchéité; ils peuvent même être constitués par des lignes de colle. The O-rings 5 and 11 can be made of any material allowing sealing; they can even be formed by lines of glue.

On pourra remarquer qu'une soupape selon la présente invention peut être vissée ou collée et ce indifféremment, l'étanchéité étant toujours garantie.  It will be noted that a valve according to the present invention can be screwed or glued and this indifferently, the sealing being always guaranteed.
