SOUPAPE DE COMMANDE DE LA CIRCULATION D'UN FLUIDE DANS UN  VALVE FOR CONTROLLING THE FLOW OF A FLUID IN A

CONDUITCONDUIT

La orésente invention se rapporte à une soupape (ou un clapet) de commande de La circulation d'un fluide, pour l'utilisation, en particulier, dans Les circuits hydrauliques d'une machine à laver la vaisselle, par exempLe comme composante du dispositif anti-débordement ou pour commander l'alimentation en eau vers une des deux  The present invention relates to a valve (or a valve) for controlling the circulation of a fluid, for use, in particular, in the hydraulic circuits of a dishwashing machine, for example as a component of the device. anti-overflow or to control the water supply to one of the two

pales de Lavage.Wash blades.

La soupape de L'invention est caractérisée en ce qu'elle comprend: - un corps qui définit une chambre en son intérieur et dans LequeL est prévu un siège de soupape, et o sont pratiquées des ouvertures respectives pour l'entrée et La sortie du fluide dans et en dehors de La chambre, - un obturateur maintenu avec du jeu à l'intérieur de ladite chambre et susceptible d'être entraîné par Le fluide qui circuLe à travers la chambre, contre ledit siège de soupape, provoquant L'interruption du flux de fluide à travers la soupape, et - un organe mobile entre une position sortante, dans laquelle il fait sailLie à l'intérieur de Ladite chambre, empêchant que Ledit obturateur ne soit entraîné par le fluide contre ledit siège de soupape, et une position rentrée, dans laquelLe iL n'interfère pas avec Ledit obturateur. La soupape de L'invention présente L'avantage d'avoir une structure très simple et un arrangement de fonctionnement déterminé de manière immédiate par La position de l'organe mobile. En fait, lorsque ce dernier est en saillie dans Ladite chambre, et interfère avec L'obturateur, la soupape permet le passage du fluide, alors que Lorsque L'organe mobile est en retrait, la pression exercée par Le fluide peut, sans obstacle, écraser L'obturateur contre son siège, interrompant le  The valve of the invention is characterized in that it comprises: - a body which defines a chamber inside and in which a valve seat is provided, and where respective openings are made for the inlet and the outlet of the fluid inside and outside the chamber, - a shutter maintained with play inside said chamber and capable of being entrained by the fluid which circulates through the chamber, against said valve seat, causing the interruption of the flow of fluid through the valve, and - a movable member between an outgoing position, in which it sails inside said chamber, preventing said shutter from being driven by the fluid against said valve seat, and a position reentry, in which the iL does not interfere with said shutter. The valve of the invention has the advantage of having a very simple structure and an operating arrangement determined immediately by the position of the movable member. In fact, when the latter protrudes into said chamber, and interferes with the shutter, the valve allows the passage of the fluid, while when the movable member is recessed, the pressure exerted by the fluid can, without obstacle, crush the shutter against its seat, interrupting the

passage du fluide.passage of the fluid.

Dans un conduit 10 qui s'étend verticalement est montée une soupape 12 comprenant un corps 14, qui supporte, à ses extrémités respectives, des manchons 16,  In a conduit 10 which extends vertically is mounted a valve 12 comprising a body 14, which supports, at its respective ends, sleeves 16,

18, et définit en son intérieur une chambre 20.  18, and defines a chamber 20 inside.

Dans le corps 14 est prévu un siège 22 de soupape, et sont pratiquées des ouvertures respectives 24, 26 pour l'entrée dans la chambre 20 et la sortie à l'extérieur de ladite chambre du fluide qui circule dans Le conduit 10,  In the body 14 is provided a valve seat 22, and respective openings 24, 26 are made for the entry into the chamber 20 and the exit outside said chamber of the fluid which circulates in the conduit 10,

seLon la direction indiquée par la fLèche 28.  according to the direction indicated by arrow 28.

A l'intérieur de la chambre 20 est maintenu, avec du jeu, un obturateur 30, profilé en forme de sphère et susceptible d'être entraîné par le fluide qui traverse la  Inside the chamber 20 is maintained, with clearance, a shutter 30, shaped in the shape of a sphere and capable of being entrained by the fluid which passes through the

chambre 20 contre le siège 22 de soupape.  chamber 20 against the valve seat 22.

Une carcasse allongée 32 est assemblée au corps 14, avec interposition d'une garniture 34, et avec une de ses portions d'extrémité 36, elle ferme une ouverture latérale 38 du corps 14, constituant une partie de la paroi de la chambre 20. L'angle formé par l'axe longitudinal de la carcasse 32 avec celui du conduit 10,  An elongated carcass 32 is assembled to the body 14, with the interposition of a lining 34, and with one of its end portions 36, it closes a lateral opening 38 of the body 14, constituting a part of the wall of the chamber 20. The angle formed by the longitudinal axis of the carcass 32 with that of the duct 10,

dans l'exemple illustré, est d'environ 60 degrés.  in the example shown, is about 60 degrees.

L'extrémité de La carcasse 32 opposée au corps supporte un soLénoïde 40 susceptible de générer un champ magnétique dans une cavité 42 à l'intérieur de la carcasse 32, dans laqueLLe est monté, de manière à pouvoir coulisser, un noyau magnétique 44 solidaire d'une  The end of the carcass 32 opposite the body supports a solenoid 40 capable of generating a magnetic field in a cavity 42 inside the carcass 32, in which it is mounted, so as to be able to slide, a magnetic core 44 secured to 'a

extrémité d'un organe mobile profilé en forme de tige 46.  end of a movable member shaped as a rod 46.

Par L'effet de l'excitation du solénoïde 40 et de l'action d'un ressort non visible dans la figure, l'extrémité distale 48 de La tige 46, qui est opposée à l'extrémité soLidaire du noyau 44, est ainsi mobile entre  By the effect of the excitation of the solenoid 40 and the action of a spring not visible in the figure, the distal end 48 of the rod 46, which is opposite to the solid end of the core 44, is thus mobile between

Lors du fonctionnement de la soupape 12, si l'organe mobile 46 se trouve dans la position rentrée, o il n'interfère pas avec L'obturateur 30, le fluide qui tend à s'écouler à travers la chambre 20 comprime l'obturateur contre le siège 22, provoquant l'interruption du flux  During the operation of the valve 12, if the movable member 46 is in the retracted position, where it does not interfere with the shutter 30, the fluid which tends to flow through the chamber 20 compresses the shutter against seat 22, causing the flow to be interrupted
