Description

La présente invention est relative à un dispositif de réglage pour robinets à fermeture temporisée. The present invention relates to an adjustment device for time-closing taps.

Selon une technique connue, la durée de la temporisation est fonction du temps nécessaire pour remplir d'eau un espace constitué par un pot obturé par un piston relié à la tige du clapet, ledit piston communiquant avec l'arrivée d'eau par l'entremise d'un petit trou calibré. According to a known technique, the duration of the time delay is a function of the time necessary to fill with water a space constituted by a pot closed by a piston connected to the stem of the valve, said piston communicating with the arrival of water by the through a small calibrated hole.

Lorsqu'on agit sur le bouton poussoir, relié à la tige de clapet, le clapet s'écarte de son siège et, simultanément, le piston précité est enfoncé jusqu'au fond du pot, I'eau contenue dans ce dernier étant chassé et sortant par l'espace compris entre sa paroi latérale et le joint du piston qui présente, à cet effet, une configuration appropriée. When the push button, connected to the valve stem, is acted on, the valve moves away from its seat and, simultaneously, the aforementioned piston is pressed to the bottom of the pot, the water contained in the latter being driven out and exiting through the space between its side wall and the piston seal which has, for this purpose, an appropriate configuration.

En relâchant le poussoir, la tige de piston, sous l'effet d'un ressort de rappel, tend à se déplacer en sens inverse pour plaquer le clapet contre son siège. Le pot étant vide ce déplacement est impossible et c'est la raison pour laquelle le piston présente un trou calibré qui permet d'introduire de l'eau dans le pot. Le piston se déplace au fur et à mesure du remplissage du pot.By releasing the pusher, the piston rod, under the effect of a return spring, tends to move in the opposite direction to press the valve against its seat. The pot being empty this displacement is impossible and this is the reason why the piston presents a calibrated hole which makes it possible to introduce water into the pot. The piston moves as the pot is filled.

Dès lors, on comprend que la durée de la temporisation dépend de nombreux paramètres parmi lesquels il faut citer : la pression de l'eau, le diamètre du trou calibré, le volume du pot. En faisant varier ces paramètres il est donc possible de faire varier la durée de la temporisation. L'expérience a montré qu'il était pratiquement impossible de faire varier par un réglage simple les paramètres cidessus. Therefore, we understand that the duration of the delay depends on many parameters among which we must mention: the water pressure, the diameter of the calibrated hole, the volume of the pot. By varying these parameters it is therefore possible to vary the duration of the time delay. Experience has shown that it is practically impossible to vary the above parameters by simple adjustment.

La présente invention qui remédie à cet inconvénient est relative à un dispositif de réglage de la durée de la temporisation d'un robinet du type décrit ci-dessus et elle est remarquable en ce que des moyens sont prévus pour limiter la course du poussoir. The present invention which overcomes this drawback relates to a device for adjusting the duration of the time delay of a tap of the type described above and it is remarkable in that means are provided for limiting the stroke of the pusher.

De cette façon, on comprend que si on réduit la course du poussoir on réduit, d'une même valeur, celle du piston ce qui a pour conséquence de réduire le volume chassé du pot et, par suite, le temps nécessaire pour le remplir à nouveau. In this way, we understand that if we reduce the stroke of the pusher we reduce, by the same value, that of the piston which has the consequence of reducing the volume expelled from the pot and, consequently, the time necessary to fill it to new.

Selon un mode de réalisation, un tel résultat peut être obtenu en prévoyant à la partie supérieure du robinet une bague filetée contre l'extrémité libre de laquelle bute le poussoir usuel.  According to one embodiment, such a result can be obtained by providing at the upper part of the valve a threaded ring against the free end of which abuts the usual pusher.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé, à titre d'exemple indicatif seulement, sur lequel la figure unique est une vue en coupe d'un robinet comportant le dispositif de l'invention. The present invention will be better understood from the description which follows, given with reference to the appended drawing, by way of indicative example only, in which the single figure is a sectional view of a tap comprising the device of the invention.

En se reportant au dessin et selon un mode de réalisation, on voit que 1 est le corps du robinet, comportant un bec 2, et renfermant, de la façon connue, une cartouche 3 comportant le siège 4 et un pot 5 dans lequel peut se déplacer un piston 6 relié à une tige 7 portant le clapet 8, ladite tige 7 étant surmontée d'un poussoir 9. Referring to the drawing and according to one embodiment, it can be seen that 1 is the valve body, comprising a spout 2, and containing, in the known manner, a cartridge 3 comprising the seat 4 and a pot 5 in which can be move a piston 6 connected to a rod 7 carrying the valve 8, said rod 7 being surmounted by a pusher 9.

Afin de simplifier les dessins, la cartouche 3 a été représentée en une seule pièce mais, dans la réalité, elle est composée par l'assemblage de plusieurs parties selon une technique connue
Losqu'on exerce une pression sur le poussoir, selon la flèche F, on repousse simultanément le clapet 8 et le piston 6. L'eau, en provenance du réseau de distribution, pénètre dans le corps par sa partie inférieure, pénètre dans la cartouche par des orifices 10, franchit l'orifice du siège 11 et est évacuée par le bec 2.
In order to simplify the drawings, the cartridge 3 has been shown in a single piece but, in reality, it is composed by the assembly of several parts according to a known technique.
When pressure is exerted on the pusher, according to arrow F, the valve 8 and the piston 6 are pushed back simultaneously. The water, coming from the distribution network, enters the body through its lower part, enters the cartridge. through orifices 10, crosses the orifice of the seat 11 and is discharged through the spout 2.

En relâchant le poussoir 9, l'eau pénètre dans le pot 5 en traversant un orifice calibré 12 prévu dans le piston 6 et le ressort 13 rappelle le clapet contre son siège. La durée de la temporisation est égale au temps mis par l'eau à remplir le pot 5 et, pendant ce temps,
I'eau s'écoule normalement par le bec 2.
By releasing the pusher 9, the water enters the pot 5 through a calibrated orifice 12 provided in the piston 6 and the spring 13 recalls the valve against its seat. The duration of the time delay is equal to the time taken by the water to fill the pot 5 and, during this time,
Water flows normally through spout 2.

Le problème posé consiste à réduire ce temps pour adapter le fonctionnement du robinet au site sur lequel il est utilise. The problem is to reduce this time to adapt the operation of the valve to the site on which it is used.

Selon l'invention, ce résultat est obtenu en utilisant une butée réglable interposée sur la trajectoire du poussoir. According to the invention, this result is obtained by using an adjustable stop interposed on the trajectory of the pusher.

Selon un mode de réalisation cette butée réglable est constituée par une bague filetée 14, vissée dans le corps. According to one embodiment, this adjustable stop is constituted by a threaded ring 14, screwed into the body.

Sur le dessin, on voit que la course du poussoir est égale à la valeur C qui correspond à la course permettant de chasser toute l'eau contenue dans le pot 5. In the drawing, we see that the stroke of the pusher is equal to the value C which corresponds to the stroke allowing all the water contained in the pot 5 to be removed.

Si on dévisse la bague 14 pour l'amener à la position représentée en traits mixtes, la course du poussoir sera égale à Ci et une partie, seulement, de l'eau contenue dans le pot sera chassée. Dans ce cas, la durée de la temporisation sera plus courte.  If we unscrew the ring 14 to bring it to the position shown in phantom, the stroke of the pusher will be equal to Ci and only part of the water contained in the pot will be expelled. In this case, the delay time will be shorter.

On comprend, dès lors, que le dispositif de l'invention permet de régler avec beaucoup de précision la durée de la temporisation. II faut noter aussi que ce dispositif de réglage, qui n'affecte pas la constitution de la cartouche, peut aussi être utilisé en combinaison avec des cartouches dites "de sécurité" selon lesquelles la temporisation commence même si le poussoir est maintenu enfoncé. It will therefore be understood that the device of the invention makes it possible to regulate with great precision the duration of the time delay. It should also be noted that this adjustment device, which does not affect the constitution of the cartridge, can also be used in combination with so-called "safety" cartridges according to which the time delay begins even if the pusher is kept pressed.

Le dispositif de l'invention peut être utilisé en combinaison avec un robinet comportant un dispositif, renforçant l'inviolabilité dudit robinet, tel que décrit dans la demande de brevet français N" 93 07029 déposée le 11 juin 1993 au nom de la demanderesse. The device of the invention can be used in combination with a tap comprising a device, strengthening the inviolability of said tap, as described in French patent application No. 93 07029 filed on June 11, 1993 in the name of the applicant.

Dans cette demande, on avait décrit un coulisseau 15 permettant de masquer l'accès au dispositif de fixation du poussoir sur la tige 7, ledit coulisseau étant porté par une bague 16 interposée entre la partie supérieure du corps 1 et le poussoir 9. In this application, a slide 15 was described making it possible to mask the access to the device for fixing the push button on the rod 7, said slide being carried by a ring 16 interposed between the upper part of the body 1 and the push button 9.

Selon la présente invention, la bague filetée 14 est vissée dans la bague 16. According to the present invention, the threaded ring 14 is screwed into the ring 16.

La bague filetée 14 peut être vissée dans un élément constituant la cartouche 3.  The threaded ring 14 can be screwed into an element constituting the cartridge 3.
