The present invention relates to an exhaust regulator module intended to be interposed between a distributor and the base plate associated therewith, of a modular system for distributing a pressurized fluid for a driving device such as a motor or hydraulic cylinder or valve.
Les modules régleur d'échappement connus ont pour inconvénients que l'accès à organe derP,glage n'est pas facile, ce qui complique considérablement les opérations de réglage. The known exhaust regulator modules have the drawbacks that access to the derP member, sliding is not easy, which considerably complicates the adjustment operations.
La présente invention a pour objectif de pallier cet inconvénient. The present invention aims to overcome this drawback.
Pour atteindre ce but, le module régleur d'échappement selon l'invention est caractérisé en ce que le dispositif de réglage d'échappement comporte un organe de réglage externe qui est situé dans une zone dégagée de la surface comprenant le plan de pose récepteur du distributeur du module régleur et est manipulable suivant une direction perpendiculaire au plan de pose. To achieve this goal, the exhaust regulator module according to the invention is characterized in that the exhaust regulator device comprises an external regulator which is located in a clear area of the surface comprising the receiving plane of the distributor of the adjuster module and can be manipulated in a direction perpendicular to the laying plane.

La figure 1 montre en une vue de principe, schémati quement > un système modulaire de distribution d'un fluide sous pression, qui comprend tris unités Ui,U2 et U3 de distribution. Chaque unité comporte un distributeur D et une plaque d'embase associée E. Dans les unités Ul et
U2, un module régleur d'échappement Pi est interposé entre le distributeur D et la plaque d'embase E.Figure 1 shows in a schematic view, schematically> a modular distribution system for a pressurized fluid, which comprises three distribution units Ui, U2 and U3. Each unit has a distributor D and an associated base plate E. In the units Ul and
U2, an exhaust regulator module Pi is interposed between the distributor D and the base plate E.
La figure 2 est une vue éclatée, en perspective,d'une unité U1 ou U2 suivant la figure i. On reconnait sur cette figure le plan de pose 20 de la plaque d'embase E w qui comprend une configuration de sept orifices, à savoir un orifice i pression 1 en communication avec un canal de pression interne 21, deux orifices d'échappement 3, 5 en communication avec des canaux internes d'échappement 22, 23, deux orifices d'utilisation ou de sortie 2 et 4 qui débouchent vers l'extérieur à la surface inférieure de l'embase Epar des raccords 24, et deux orifices de commande 12, 14 dont les raccords extérieurs sont représentés
en 46 (figure 8). Le plan de pose du distributeur présente la même configuration d'orifices.Les canaux internes 21, 22, 23 de la plaque d'embase E traversent celle-ci entièrement pour pouvoir communiquer avec les canaux correspondants d'autres plaques d'embase, commecela ressort de la figure 1. Figure 2 is an exploded perspective view of a unit U1 or U2 according to Figure i. We recognize in this figure the installation plane 20 of the base plate E w which comprises a configuration of seven orifices, namely a pressure orifice 1 in communication with an internal pressure channel 21, two exhaust orifices 3, 5 in communication with internal exhaust channels 22, 23, two use or outlet orifices 2 and 4 which open outwards to the lower surface of the base E by connections 24, and two control orifices 12 , 14 whose external connections are shown
at 46 (figure 8). The distributor installation surface has the same configuration of orifices. The internal channels 21, 22, 23 of the base plate E pass through it entirely so as to be able to communicate with the corresponding channels of other base plates, such as spring of figure 1.
Comme le montre la figure 2, la surface supérieure 25 du module régleur d'échappement M selon l'invention est également conformé en plan de pose et présente une configuration de cinq orifices 1', 2', 3', 4', 5' qui correspondent aux orifices 1 à 5 du plan de pose de la plaque d'embaseE. Il est à noter que la surface inférieure du module M comporte un plan de pose avec la même configuration d'orifices que la surface supérieure 25. As shown in FIG. 2, the upper surface 25 of the exhaust regulator module M according to the invention is also shaped in laying plan and has a configuration of five orifices 1 ', 2', 3 ', 4', 5 ' which correspond to the openings 1 to 5 of the installation plane of the base plate. It should be noted that the lower surface of the module M comprises a laying plane with the same configuration of orifices as the upper surface 25.
Le module régleur M est monté de façon amovible sur la surface supérieure 20 formant surface de pose de la plaque d'embase U, par l'intermédiaire de quatre vis 26 qui traversent le module M et peuvent être vissées dans des trous filetés 27 pratiqués dans la surface 20 de la plaque E. La partie formant tête de chaque vis 26 est pourvue d'un alésage fileté 28 dans lequel s'engage une is qube vis 29 destinée à la fixation du distributeur D au module régleur M. Comme cela est illustré par les lignes fantômes, ce système de vis de fixation assure un positionnement relatif exact des trois éléments, c'est-à-dire du module régleur M, de la plaque d'embase E et du distributeur D. The adjuster module M is removably mounted on the upper surface 20 forming the mounting surface of the base plate U, by means of four screws 26 which pass through the module M and can be screwed into threaded holes 27 made in the surface 20 of the plate E. The head portion of each screw 26 is provided with a threaded bore 28 in which engages a is qube screw 29 intended for fixing the distributor D to the adjusting module M. As illustrated by the phantom lines, this fixing screw system ensures exact relative positioning of the three elements, that is to say of the adjusting module M, of the base plate E and of the distributor D.
En se reportant aux figures 3 à 7, on décrira ci-après le dispositif de réglage d'échappement incorporé au module régleur M. Referring to FIGS. 3 to 7, the exhaust adjustment device incorporated in the adjusting module M will be described below.
Le dispositif de réglage d'échappement comprend une buse due regip 30, de forme générale cylindrique (figure 4), qui est montée rotative dans des palliers 31, 32 à l'intérieur du module régleur M (figure 3) Chaque buse de réglage 30 s'étend parallèlement à un orifice oblongue d'échappement 3'^ ,-- 5-' à l'-intérieur du- module M,- dans--un-- canal interne 33 qui relie les orifices d'échappement 3' ou 5' respectivement prévus dans la face supérieure 25 et la surface inférieure du module régleur M (figure 3). The exhaust adjustment device comprises a due regip nozzle 30, of generally cylindrical shape (FIG. 4), which is rotatably mounted in bearings 31, 32 inside the regulating module M (FIG. 3) Each adjustment nozzle 30 extends parallel to an oblong exhaust port 3 '^, - 5-' inside the module M, - in - an-- internal channel 33 which connects the exhaust ports 3 'or 5 'respectively provided in the upper face 25 and the lower surface of the adjusting module M (FIG. 3).
Comme il ressort notamment de la figure 4, chaque buse de réglage est formé par un élément tub ire fermé à ses exbiFités et porwu de deux évidements oblongues 35 -diamétra- lement opposés. Les bords 36 qui s'étendent axialement sont sensiblement parallèles et rectilignes. Mais,pour chaque évidement- 35 , dans la zone formant bord 36, sensiblement au milieu de celui-ci, est prévu un évidement supplémentaire 37 qui s'étend perpendiculairement à l'axe de la buse et dont la largeur diminue progressivement à partir du bord 36.Comme l'illustrent les figures 5 et 7, en raison de son montage et de sa configuration, qui viennent d'autre décrits, la buse de réglage 30 est susceptible de recouvrir et d'obturer 2 de façon plus ou moins complète, les orifices d'échappement 3' ou 5' du module de réglage M, suivant sa position angulaire En raison de l'évidement 37 de largeur variable en direction de la rotation de la buse 30, l'-obturation se fait progressivement. As can be seen in particular from FIG. 4, each adjustment nozzle is formed by a tubular element closed at its ends and porwu of two oblong recesses 35 - diametrically opposite. The edges 36 which extend axially are substantially parallel and straight. However, for each recess 35, in the edge forming region 36, substantially in the middle thereof, there is provided an additional recess 37 which extends perpendicular to the axis of the nozzle and whose width gradually decreases from the edge 36.As illustrated in FIGS. 5 and 7, due to its mounting and its configuration, which have just been described, the adjustment nozzle 30 is capable of covering and closing 2 more or less completely , the exhaust orifices 3 'or 5' of the adjustment module M, depending on its angular position Due to the recess 37 of variable width in the direction of the rotation of the nozzle 30, the obturation is done gradually.
Dans le cas de la figure 5, la section s du passage de fluide est très réduite, freinant ainsi la détente de la pression à l'atmosphère. Dans la représentation de la figure 6, la section s de passage du fluide est déjà plus importante et sur la figure 7 la buse de réglage 30 libère complètement l'orifice d'échappement 3' et par conséquent le canal de passage.In the case of FIG. 5, the section s of the fluid passage is very reduced, thus slowing down the expansion of the pressure to the atmosphere. In the representation of FIG. 6, the cross section for the passage of the fluid is already greater and in FIG. 7 the adjusting nozzle 30 completely releases the exhaust orifice 3 ′ and consequently the passage channel.
Pour assurer l'entrainement en rotation de la buse de réglage 30, cele-ci est pourvue à une extrémité d'une partie annulaire crantée 39 et une vis 40 est disposée dans un alésage 41 pratiqué dans le module régleur M. To ensure the rotational drive of the adjustment nozzle 30, the latter is provided at one end with a notched annular part 39 and a screw 40 is disposed in a bore 41 formed in the regulator module M.
L'alésage 41 s'etend perpendiculairement à la fois à l'axe de la buse de réglage 30 et à la surface supérieure 25 du module régleur M. Il est situé de telle façon par rapport à la plaie crantée 39 de la.b.us.e que cette partie et la vis s!engrènent mutuellement. Etant donnéque.la.vis 40 est montée librement rotatif dans l'alésage 41, toute rotation de la vis 40 provoque une rotation de la buse de réglage 30.Comme il ressort de la figure 3, les deux alésages 41 pour les deux vis 40 de commande des deux buses de réglage d'échappement, chacune associée à un orifice d'échappement 3', 5' sont situés de telle manière qu'ils se trouvent à côté du distributeur D et que les têtes 42 des vis de réglage soient ainsi dégagées, Ainsi les vis 40 sont aisément manipulables d'en haut, c'est-à-dire à partir de la face supérieure. Suivant le pas donné au filetage de la vis 40 et le module du crantage de la partie 39 de la buse de réglage 30, chaque tour de vis fera tournera buse 30 suivant un angle prédéterminé.The bore 41 extends perpendicular both to the axis of the adjusting nozzle 30 and to the upper surface 25 of the adjusting module M. It is located in such a way relative to the notched wound 39 of la.b. us.e that this part and the screw! mesh with each other. Since the screw 40 is freely rotatably mounted in the bore 41, any rotation of the screw 40 causes the adjustment nozzle 30 to rotate. As shown in FIG. 3, the two bores 41 for the two screws 40 for controlling the two exhaust adjustment nozzles, each associated with an exhaust orifice 3 ′, 5 ′ are located such that they are located next to the distributor D and that the heads 42 of the adjustment screws are thus released, Thus the screws 40 are easily manipulated from above, that is to say from the upper face. According to the pitch given to the thread of the screw 40 and the notch module of the part 39 of the adjustment nozzle 30, each turn of the screw will rotate the nozzle 30 at a predetermined angle.
La forme de la buse 30 est,d'autre part, étudié afin que l'ouverture et la fermeture des orifices 3', 5' soient proportionnelles au nombre de tours de la vis 40. Par exemple les conditions représentées à la figure 5 sont obtenues en réalisant deux tours avec la vis. La position représentée à la figure 6, de la buse 30 est obtenue en effectuant en plus deux tours 3/4 avec la vis 40. Ensuite, le plein passage suivant la figure 7 est réalisé après avoir effectué cinq tours et demi avec la vis 40 Bien entendu, le nombre de tours de la vis est uniquement donné à titre d'exemple.The shape of the nozzle 30 is, on the other hand, studied so that the opening and closing of the orifices 3 ', 5' are proportional to the number of turns of the screw 40. For example, the conditions represented in FIG. 5 are obtained by making two turns with the screw. The position shown in FIG. 6, of the nozzle 30 is obtained by carrying out in addition two 3/4 turns with the screw 40. Then, the full passage according to FIG. 7 is carried out after having carried out five and a half turns with the screw 40 Of course, the number of turns of the screw is only given by way of example.
Pour faciliter l'emploi de capteurs à chute de pression, le module réducteur d'échappement M comporte des orifices 44 de piquage de pression, un orifice à chaque côté latéral. Chaque orifice 44 est relié à l'intérieur du module régleur M à un orifice d'utilisation ou de sortie 2', 4'. Les orifices de piquage 44 sont en outre reliés chacun à un orifice de pilotage ou de commande 46 de la plaque d'embase E, par l'intermédiaire d'un tube 45 (figure 8). To facilitate the use of pressure drop sensors, the exhaust reducing module M has orifices 44 for pressure taps, one orifice on each lateral side. Each orifice 44 is connected inside the regulating module M to a use or outlet orifice 2 ′, 4 ′. The tap holes 44 are also each connected to a pilot or control hole 46 of the base plate E, by means of a tube 45 (FIG. 8).
Comme le montre la figure 2, un capteur à chute de pression C peut être fixé sur une plaque P et l'ensemble susceptible d'être intégré sur la surface supérieure du distributeur D. As shown in FIG. 2, a pressure drop sensor C can be fixed on a plate P and the assembly capable of being integrated on the upper surface of the distributor D.
Il est à noter que les quatre éléments, à savoir la plaque d'embase E, le module régleur d'échappement M, le distributeur D et l'ensemble plaque P-capteur à chute de pression C sont assemblés de façon compacte, sans autre câblage que celui pour les orifices d'utilisation. It should be noted that the four elements, namely the base plate E, the exhaust regulator module M, the distributor D and the plate P-pressure drop sensor assembly C are compactly assembled, without further wiring than that for the use orifices.
