Abstract

The invention proposes a multi-position valve subassembly (1, 24, 31) which is assembled and adjusted before being installed. In this subassembly, two valve seats (2, 3) are moved into a precisely spaced relationship and a spherical closing element (7) interacting alternately with each of the two valve seats is included in this adjustment operation. The closing element (7) is actuated by a tappet (37) which engages on it from outside through a valve seat (2). At least one filter (10, 16) is integrated into the valve subassembly (1, 24, 31). The valve subassembly (1, 24, 31) can be constructed alternatively as a 2/2-way, 3/2-way or 3/3-way valve and can preferably be used for anti-lock systems in motor vehicles.

Description

La présente invention concerne un organe de distribution à plusieurs positions, comportant un clapet mobile entre deux sièges de soupape écartés et obturant alternativement un des sièges. Un tel organe de distribution est connu (demande de brevet de la République fédérale d'Allemagne publiée sous le nO 11 43 069). Cet organe connu est certes destiné au montage complet dans un corps, mais n'exige aucun préajustage, car la distance entre les deux sièges n'intervient pas. La bille d'obturation se déplace automatiquement entre les deux sièges. L'amplitude de sa course est negligeable.  The present invention relates to a multi-position distribution member, comprising a valve movable between two separated valve seats and alternately closing one of the seats. Such a distributor is known (patent application from the Federal Republic of Germany published under No. 11 43 069). This known member is certainly intended for complete mounting in a body, but does not require any pre-adjustment, since the distance between the two seats does not intervene. The shutter ball moves automatically between the two seats. The amplitude of its course is negligible.

Lorsqu'un ajustage de telles scupapes est nécessaire, il n'est possible que séparément pour chaque pièce, ce qui occasionne des courts élevés. Il en est de même quand la partie soupape est ajustée avec une partie de commande. When an adjustment of such scupapes is necessary, it is only possible separately for each piece, which results in high short. The same is true when the valve part is adjusted with a control part.

Il convient en outre de noter que de tels organes de distribution de petite taille, tels que des soupapes miniatures, sont très sensibles à l'encrassement. Des filtres sont alors habituellement incorporés dans la canalisation d'alimentation de ces organes de distribution. It should also be noted that such small dispensing members, such as miniature valves, are very sensitive to fouling. Filters are then usually incorporated in the supply line of these distribution members.

Ces filtres ne peuvent toutefois pas interdire une perturbation du fonctionnement par les saletés vagabondes.These filters cannot however prevent a disturbance of the operation by the vagabond dirt.

Selon une caractéristique essentielle de l'invention, la distance entre les deux sieges disposés sur des pièces séparées est ajustable avant le montage de l'organe en plusieurs parties; et le clapet intervient dans cet ajustage. L'organe de distribution à plusieurs positions selon l'invention présente l'avantage suivant : le montage de même que l'ajustage et le contrôle sont limités au sous-ensemble. Il est possible lors du montage de tenir compte de toutes les fonctions importantes de la soupape, et surtout de la course. Le contrôle est en outre important. Le contrôle de l'organe de distribution permet de verifier toutes les caractéristiques fonctionnelles de la soupape, telles que l'étanchéité des sièges ou le débit. According to an essential characteristic of the invention, the distance between the two seats arranged on separate parts is adjustable before mounting the member in several parts; and the valve is involved in this adjustment. The multi-position distribution member according to the invention has the following advantage: the mounting as well as the adjustment and control are limited to the sub-assembly. It is possible during assembly to take into account all the important functions of the valve, and especially the stroke. Control is also important. The control of the distribution member makes it possible to verify all the functional characteristics of the valve, such as the tightness of the seats or the flow rate.

Une construction compacte de la soupape permet de disposer des filtres aussi bien à l'entrée qu'à la sortie de canalisations de liaison. I1 en résulte l'avantage suivant : la partie du volume contenant des saletes vagabondes est très petite. Les coûts d'ébarbage des pièces de raccordement sont enfin très faibles. Un tel petit organe de distribution se prête aussi particulièrement bien au transport. A compact construction of the valve allows filters to be placed both at the inlet and at the outlet of connecting pipes. This results in the following advantage: the part of the volume containing vagabond filth is very small. The costs of deburring the connecting parts are finally very low. Such a small distribution member also lends itself particularly well to transport.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description détaillée de plusieurs exemples de réalisation et du dessin annexé sur lequel: la figure 1 représente une première forme de réalisation avec corps métallique et deux filtres; la figure 2 représente une forme de réalisation avec corps filtrant; et la figure 3 représente un modèle avec corps métalliqueen trois parties. Other characteristics and advantages of the invention will be better understood with the aid of the detailed description of several exemplary embodiments and of the appended drawing in which: FIG. 1 represents a first embodiment with a metal body and two filters; Figure 2 shows an embodiment with filter body; and Figure 3 shows a model with metallic body in three parts.

Un organe de distribution l comporte deux sièges 2,-3 de soupape, dont un est prévu dans un corps borgne 4 et l'autre sur une base 5, fermant le corps borgne 4 dans le bas. A distribution member 1 comprises two valve seats 2, -3, one of which is provided in a blind body 4 and the other on a base 5, closing the blind body 4 at the bottom.

Le corps 4 comporte une chambre intérieure 6, dans laquelle sont disposés un clapet 7 constitué par une bille, un ressort Belleville 8 se plaçant sous le clapet 7, un ressort 9 agissant sur le clapet 7 et une cartouche filtrante 10 en forme de manchon. The body 4 comprises an interior chamber 6, in which are arranged a valve 7 constituted by a ball, a Belleville spring 8 placed under the valve 7, a spring 9 acting on the valve 7 and a filter cartridge 10 in the form of a sleeve.

Le second siège 3 est également positionné dans la chambre 6. The second seat 3 is also positioned in chamber 6.

I1 est réaliste à l'extrémité intérieure d'un tenon creux 11, façonné sur la pièce de base 5. Cette dernière comporte un rebord 12, logé dans un alésage 13 de la chambre intérieure 6, de diamètre plus élevé. Sa fixation sur le corps 4 s'effectue à l'aide de trois pattes 14, découpéessur la paroi de l'alesage 13 et équidistantes sur la circonférence. Un filtre 16 circulaire est logé dans un autre evide- ment 15 à la face inférieure du cylindre borgne. Le corps 4 présente une surface extérieure cylindrique, comportant un évidement annulaire 17, relié à la chambre intérieure 6 par des perçages radiaux 18.L'évidement 17 forme sur la paroi extérieure du corps 4 deux zones de guidage 19 et 20 de même diamètre, qui constituent lors du montage du corps 4 dans un alésage des surfaces d'ajustement, portantes et d'étanchéité. I1 is realistic at the inner end of a hollow stud 11, shaped on the base part 5. The latter has a flange 12, housed in a bore 13 of the inner chamber 6, of larger diameter. Its attachment to the body 4 is carried out using three legs 14, cut out on the wall of the bore 13 and equidistant on the circumference. A circular filter 16 is housed in another recess 15 on the underside of the blind cylinder. The body 4 has a cylindrical external surface, comprising an annular recess 17, connected to the internal chamber 6 by radial holes 18. The recess 17 forms on the external wall of the body 4 two guide zones 19 and 20 of the same diameter, which constitute during assembly of the body 4 in a bore of the adjustment, bearing and sealing surfaces.

La chambre intérieure 6 est reliée par des perçages radiaux 18 à une canalisation d'utilisation 21. La face inférieure du cylindre borgne est reliée à une pompe par une canalisation 22 et la face supérieure a une canalisation de décharge 23. The inner chamber 6 is connected by radial bores 18 to a use pipe 21. The underside of the blind cylinder is connected to a pump by a pipe 22 and the upper face has a discharge pipe 23.

Tous les paramètres fonctionnels importants, tels que realisation des sièges de soupape, dimensionnement du clapet et course de la soupape sont pris en considération et contrôlés lors du montage de l'organe de distribution 1. Après l'assemblage, l'étanchéité et le débit sont contrôlés en particulier. L'emploi des filtres 16 et 10 prevus à l'entrée et à la sortie est facile en particulier du fait de l'encombrement réduit de l'organe de distribution 1, car le pourcentage du volume contenant des saletés vagabondes est très faible. All important functional parameters, such as construction of the valve seats, sizing of the valve and stroke of the valve are taken into account and checked during assembly of the distribution member 1. After assembly, tightness and flow are controlled in particular. The use of filters 16 and 10 provided at the inlet and at the outlet is easy in particular because of the reduced size of the dispensing member 1, since the percentage of the volume containing vagrant dirt is very low.

Dans le modele selon figure 1, la liaison des pièces détachées est assurée par les pattes 14. La construction selon figure 2 est possible dans le cas d'un organe de distribution 24 dans lequel un filtre de sortie 25 est réalisé sous forme d'un manchon comportant à chaque extrémité un rebord annulaire de fixation 26 ou 27. Le corps métallique de soupape est réalise en trois parties dans ce cas et comprend le couvercle 28, la partie médiane 29 et la base 30,
Le couvercle 28 et la base 30 portent les sièges 2 ou 3. La construction et le fonctionnement correspondent par ailleurs pratiquement à ceux de l'organe de distribution selon figure 1.In the model according to FIG. 1, the connection of the spare parts is ensured by the lugs 14. The construction according to FIG. 2 is possible in the case of a distribution member 24 in which an outlet filter 25 is produced in the form of a sleeve comprising at each end an annular fixing flange 26 or 27. The metal valve body is produced in three parts in this case and comprises the cover 28, the central part 29 and the base 30,
The cover 28 and the base 30 carry the seats 2 or 3. The construction and the operation also correspond practically to those of the dispensing member according to FIG. 1.

La figure 3 représente un organe de distribution 31, dans lequel un couvercle 32 est fixé par un rebord annulaire 33 sur une pièce mediane 34, qui est fixée par un rebord annulaire 35 sur une base 36. FIG. 3 represents a dispensing member 31, in which a cover 32 is fixed by an annular rim 33 on a central part 34, which is fixed by an annular rim 35 on a base 36.

La construction et le fonctionnement correspondent par ailleurs pratiquement à ceux des organes de distribution selon figures 1 et 2; les filtres 10 et 15 sont incorporés comme dans le modèle selon figure 1.The construction and operation also correspond practically to those of the distribution members according to Figures 1 and 2; filters 10 and 15 are incorporated as in the model according to figure 1.

Les trois organes de distribution 1, 24 et 31 sont destinés à l'emploi comme distributeurs 3/2. Il est évident qu'ils sont également utilisables en distributeurs 2/2 ou 3/3. The three distribution members 1, 24 and 31 are intended for use as 3/2 distributors. It is obvious that they can also be used in 2/2 or 3/3 distributors.

Un poussoir 37 est prévu pour commander la bille d'obturation 7 entre les deux sièges de soupape 2 et 3; il pénètre dans l'organe de distribution 1, 24, 31 à travers le siège 2 et agit sur la bille d'obturation 7. A pusher 37 is provided for controlling the closure ball 7 between the two valve seats 2 and 3; it enters the dispensing member 1, 24, 31 through the seat 2 and acts on the shutter ball 7.

Les organes de distribution 1, 24 et 31 sont destinés à l'emploi dans des équipements antiblocage, qui exigent des éléments de soupape à commutation particulièrement précise. The distribution members 1, 24 and 31 are intended for use in anti-lock equipment, which require particularly precise switching valve elements.

Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art au principe et aux dispositifs qui viennent d'être décrits uniquement à titre d'exemples non limitatifs, sans sortir du cadre de l'invention.  Of course, various modifications can be made by those skilled in the art to the principle and to the devices which have just been described only by way of nonlimiting examples, without departing from the scope of the invention.
