Description

Robinet. 0n a dejä propose de rea.liser des robi- nets en mat.ieres plastiques m.oulables, telles que les phenopla-stes par :exemple. Toute:fois, des inc.onveni.ents se sont reveles en ce qui eoncerne plus speeialement la. realisation d3 1'etancheite entre la tige du robinet et son g iidage. Faucet. 0n has already proposed to rea.liser faucets m.ouldable plastic mat.ieres, such as phenoplasts for example. However, inc.onveni.ents were revealed in what eoncerne more speeiament there. realization d3 1'etancheite between the stem of the valve and its g iidage.

Jusqu'ici, le seul moyen d'obtenir cP:tte etancheite dans les divers types de robinets, qu'ils soient en metal ou en mauere plastique, eonsistait ä disposer un presse-etoupe autour de la tige avee la garniture et 1'ecrou de serrage habituell. Ce dispositif n'est jamais Parfait, ca-r la garniture s'use de faQon re@ lativ-cment rapide saus 1'effet du frottement de la tige et n'assure plus 1'etaneheite. Mais le;s inconvenients du presse-etoupe sont en core plus sensibles dann 1e eas des robinets en matiere plastique; dans ces derniers, en effet, la Pression exercee Sur la- garniture du prosse-etoupe pour obtenir 1'etaneheite risque de provoquer des ruptures. Ce danger est aceru du fait que la tige en matiere plas- tique dopt 1e diametre est plus grand que Jans le".s robinets en metal, afin d'o:ffrir une resistaneE#. suffisante, presentp une surfa.ee de contaet avee 1a, garniture du presse-etoupe relativement importante et exerce, par Suite, un effort plus grand .Sur la garniture d'etan- chAite. Au Surplus, la tige en matiere plan. tique moulee a nbeessairement une depouille et sa cooperation avec la, garniture d'etan- eheite est de ee fait mauvaise. Si la garni- eure serre bien sur les Parties les moins larges de la tige, 1e serrage est trog fort sur les Parties plus larges et inversement. Until now, the only way to obtain this tightness in the various types of taps, whether metal or plastic, was to place a stuffing box around the stem with the gasket and the nut. usual tightening. This device is never perfect, ca-r the lining wears faQon re @ lativ-cment fast saus 1'Effect of friction of the rod and no longer ensures 1'etaneheite. But the disadvantages of the stuffing box are even more noticeable in the case of plastic taps; in the latter, in fact, the pressure exerted on the packing of the stuffing box to obtain 1'etaneheite risks causing ruptures. This danger is aggravated by the fact that the plastic stem has a larger diameter than metal taps, in order to provide sufficient resistance, present a surface of contact and with 1a, packing of the stuffing box relatively important and exerts, as a result, a greater force on the packing of watertightness. The seal is therefore poor If the seal fits well on the less wide parts of the rod, the tightness is too strong on the wider parts and vice versa.

La presente invention eise ä remedier ä ces ineonvenie:nts et a pour objet un robinet, c.a- racterise en ce qu'il comporte, entre 1a. tige de son obturateur et une de ses Parties fixes, un anneau d'etancheite elasstique serre elas- tiquement entre ladite tige :et ladite Partie fixe, cet anneau ayant une section lobbe dopt des saillies, engagees dann des creux que pres.entent la tige et ladite Partie fixe du ro- binet, cooperent avec ces cr,eux ä la maniere des dents d'un engrenage, 1'anneau decrivant ainsi un roulement en meme temps qu'il se defo:rme elastiquement quand la tige se de- place en translation, de Sorte que 1'anneau aecompagne 1e mouvement de translation de 1a tige sann frottement appreeiable. The present invention aims to remedy these drawbacks and relates to a tap, characterized in that it comprises, between 1a. rod of its obturator and one of its fixed parts, an elastic sealing ring clamps elastically between said rod and said fixed part, this ring having a lobed section has projections, engaged in the hollows that the rod pres.entent and said fixed part of the tap, cooperate with these crests like the teeth of a gear, the ring thus describing a bearing at the same time as it deforms elastically when the rod moves. in translation, so that the ring aecompagne the first translational movement of the rod without appreciable friction.

L'elimination de la rotation de 1a tige peut etre obtenue de diverses faqons. La p-i- gnee de manceuvre RTI ID="0001.0271" WI="5"HE="4" LX="1366" LY="1746"> qui decrit un mouv{:m-iit: helicoidal peut etre, par exemple, reliee ä la tige par emmanchement entre deux portees de celle-ei permettant ä. 1a poignes de tourner librement Sur la tige. Elimination of stem rotation can be achieved in a variety of ways.

Bien que lese perfeetionne.ments qui dec:ou- 'lent de 1'invention soient pariticuliärement pre- cieux pour les robinets en matiere plastique, leur application aux robinets en metal reste avantageuse, du fait de la suppression du press e-etoupe et de 1'usure moindre de 1a ga.r- niture; favorable au maintien de 1'etancheite. Le dessin annexe represente, ä titre d'exe@mple, une forme d'execution de Fobjet de Finvention et des va.riantes de d@tails. Although the improvements which flow from the invention are particularly valuable for taps made of plastic material, their application to taps made of metal remains advantageous, because of the elimination of the gland and the less lining wear; conducive to maintaining watertightness. The appended drawing represents, by way of example, one form of execution of the object of the invention and variants of details.

La tige 1 Parte un obturateur 2 cooperant avec un siege 3 prevu dann 1e corps du ro- binet 9 (dann 1'exemple represente, 1'obtura- teur 2 est forme par une rondelle en matier(, elastique, simplement enfileei nur un gou- jon lcr. prPVu ä. 1'extremite de la, tige).

Seule, la eomposante reetilignc@ et parallele ä Faxe de la tige de ce mouvement lielicoidal est communiquee ä la tige, ä, Fex clusion de la composante de rotation, la poi- gnee portant ä oet effet un rebord 12 qui vierst s'engager entre deux collets circulaires 13 et 14 prevus sur la tige. The rod 1 leaves a shutter 2 cooperating with a seat 3 provided in the first body of the valve 9 (in the example represented, the shutter 2 is formed by a washer made of elastic material, simply threaded on a gou - jon lcr. prPVu ä. 1'extremite de la, stem). a helical movement, said handle bearing for this purpose an internal thread 7 cooperating with a thread 8 provided on a bonnet 4 which is screwed at 4' on the body of the tap. ä The axis of the rod of this smooth movement is communicated to the rod, ä, the exclusion of the component of rotation, the handle carrying for this purpose a flange 12 which vierst engage between two circular collars 13 and 14 provided on the rod.

L'etancheite du guidage de la tige ä tra vers 1e Bonnet 4 est obtenue au moyen d'un anneau d'etancheite 16, de preference en caoutcliouc naturel au synthetique. Dans 1'exemple represente au dessin, cet anneau presente une section transversale quadri- lob6e qui s'est revelee particulierement avan- tageuse. Le:dit anneau a un diametre interne tel qu'il soit serre par son elastieite sur 1a. tige 1, 1'un des loben s'engageant dann une rainure cireulaire 17 prevue nur la tige; d'autre pari, ä Fetat de repo,s, son diamefre extexne est plus Brand quo 1e diametre in terne du Bonnet 4, pour qu'il soit appuy elastiquement contre ce Bonnet par un de ses loben. L'anneau se trouve ainsi comprime elastiquement entre la tige et 1e Bonnet 4 et il assure 1'etanaheite. La Pression de 1'eau, lorsque 1e rcbinet eist euvert (fig.l Partie de drohe), ne peut, en effet, quo comprimier 1'anneau davantage entre 1e rebord 17a. de 1a rainure 17 @et un epaulement eirculaire 4a du bonnot 4. Cette compression de 1'anneau qizi ,xe#ree, de ba.s en haut, tend ä; augmenter s 'e son diametre et par Suite son serrage contre la tige et 1e bonnot 4, toute fuite d'eau etant ainsi evitee. Enfin, du fait du serrage de Fanneau entre la tige et 1e bonnot 4, une ro- tation de la tige, qui tendrait ä s'amorcer lorsqu'on tourne la poignee 6, est empechee par frottement; la poignee tourne ainsi libre- ment sur la tige et ne lui communique, par 1e rebord 12, quo son mouvement de transla- tion vertical_ La Position oblique des rebords de 1a rainure 17 de la tige et los epaulements etages 4a et 4b du Bonnet 4, permettent unn sort e de roulement de Farmeau 16 quand la tage prend diverses positions entre la forme- ture e@ 1'ouverttire du robinet; 1e Profil lobe coopere en quelque Sorte ä la maniere Tun Profil d',engrenage avec 1e Profil de son logement. 0n evite ainsi. que la garniture na prenne des pos,itions obliques, saus Feffet de Pressions d',eau irregulieres ou de difArences d'elasticite 1 .,9 long de la surface de con- taet de la garniture. The tightness of the guide of the rod through the cup 4 is obtained by means of a sealing ring 16, preferably made of natural or synthetic rubber. In the example represented in the drawing, this ring has a four-lobed cross-section which has proved to be particularly advantageous. Le: said ring has an internal diameter such that it is tightened by its elasticity on 1a. stem 1, one of the lobes engaging in a waxy groove 17 provided on the stem; on the other hand, in the state of rest, its external diameter is greater than the internal diameter of the Cup 4, so that it is pressed elastically against this Cup by one of its lobes. The ring is thus elastically compressed between the rod and the first Cup 4 and it ensures 1'etanaheite. The pressure of 1'eau, when the 1e rcbinet is opened (fig.l Part of right), can, in fact, quo compress 1'ring more between the 1st edge 17a. of 1a groove 17 @and a circular shoulder 4a of the bonnet 4. This compression of the qizi ring, xe#ree, from ba.s upwards, tends to; increase its diameter and subsequently its tightening against the rod and the first bonnet 4, any leakage of water being thus avoided. Finally, due to the tightening of the ring between the rod and the bonnet 4, a rotation of the rod, which would tend to start when the handle 6 is turned, is prevented by friction; the handle thus rotates freely on the rod and communicates to it, via the first edge 12, only its vertical translational movement. The oblique position of the edges of the groove 17 of the rod and the shoulders 4a and 4b of the Cup 4 , allow a sort of rolling of Farmeau 16 when the stage takes various positions between the form- e @ 1'ouvertire of the tap; The lobe profile cooperates in a way like a gear profile with the profile of its housing. 0n avoids so. that the packing does not assume oblique positions, except for the effect of uneven water pressures or differences in elasticity 1 .,9 along the contact surface of the packing.

A. la fin du mouvement de fermeture du robinet, un s.urcroit d',effort sur la poignee est supporte par 1'obturateur 2 qui vient se deformer elastiquement contre 1e siege 3, et ]es organes en matiere plastique ne risquent pas d'etre deteriores. Pour eviter qu'ä 1a. fin du mouvement d'ouverture, au contraire, un effort excessif sur la poigmee n'endo,m- mage les filetages ou les autres Parties trans- met.tant 1'eff@:rt, par exemple 1e rebord 12, il est prevu un d@bra.yage des Filets de vis 7 et 8 vers 1a fin du inouvement d'ouverture. A cet, effet, la hauteur lz., sur laquelle les Filets 7 de la poignee viennent en Prise avec los Filets 8 du bonnot 4 lorsque 1e robinet est forme, est limitee de maniere quo 1e dP- vissage complet de la poignee, c'e,st-ä-dir(sa. montee de la hauteur h, entraine une, com- pression elastique modere, de 1'arin.eau 16 entre 1e rebord inArieur 17a de la rainure 17 de la tige et 1'epaulement 4a du Bonnet 4. Cette compression de Farmeau 16, vors la fin du mouvement de la poignee, s'o:ppose au devissage complet de celle-ei, mais si an sur- monte rette compression par suite d'un sur- croit d'effort exerce sur la poignee, los filets 7 echappent completement .aux Filets 8 et la poignee peut des lors tourner folle, avant d'avoir et, soumise ä un effort exces- sif. L'effort elastique de Fanneau 16 a. Tailleurs pour effet de maintenir los Filets de la poignee au eontact des filets du bon not 4, 5 Fencontre de 1a. Pression de Fea.u; de la. sorte, 1e vissage de la poignee pour la fermeture s'.effectue pa-r simple rotation, saus qu'i.l soit necessaire d'exereer une poussPe Parallele ä Faxe de la tige 1, pour vaincre la Pression de Feau et remettre los Filets en Prise. At the end of the closing movement of the tap, an additional force on the handle is supported by the shutter 2 which is deformed elastically against the first seat 3, and] the plastic material organs are not likely to to be deteriorated. To avoid that at 1a. end of the opening movement, on the contrary, an excessive force on the handle does not damage the threads or the other Parts transmitting the force, for example the first flange 12, it is expected a d@bra.yage of the threads of screws 7 and 8 towards the end of the opening inouvement. For this purpose, the height lz., on which the threads 7 of the handle come into engagement with the threads 8 of the bonnet 4 when the first tap is formed, is limited so that the complete first screwing of the handle, it e, st-à-dir (sa. rise of the height h, causes a moderate elastic compression of the arin.eau 16 between the first lower edge 17a of the groove 17 of the rod and the shoulder 4a of the Cup 4. This compression of Farmeau 16, at the end of the movement of the handle, opposes complete unscrewing of the latter, but if it overcomes this compression as a result of an increase in effort exerted on the handle, the threads 7 escape completely from the threads 8 and the handle can then spin wildly, before having been subjected to an excessive force. maintain the threads of the handle in contact with the threads of the correct note 4, 5 against the pressure of the pressure; in this way, the 1st screwing of the handle for closing is carried out by simple rotation, without that it is necessary to exert a thrust parallel to the axis of the rod 1, to overcome the pressure of the water and to put the threads back into engagement.

Pour Fenga.gement de 1a tige dans la poignee, l'extremite superieure de la tige nst munie de traits de Beie 15 en croix (voir fig.2) qui permettent de reduire par com- pression 1e diametre de 1a tige ä son extr@- mite, afin de Pintroduire dans la poignee, 1'elasticite de la tige jouant ensuite paur maintenir 1e rebord 12 entre les collets 13 et 14. For the engagement of the rod in the handle, the upper end of the rod is provided with cross-shaped Beie lines 15 (see fig. 2) which make it possible to reduce by compression the diameter of the rod at its end. - mite, in order to introduce it into the handle, the elasticity of the rod then playing to maintain the first rim 12 between the collars 13 and 14.

Le collet 14 prevu de la tige 1 presente ä sa Base en 14a un rebord arrondi qui vient eooperer avec Forifice, 4c du Bonnet 4 pour permettre 1e demontage de la tige. Ce de- montage s'effectue de la fagon suivante: en devissant 1e Bonnet 4RTI ID="0003.0274" WI="5" HE="4" LX="1388" LY="614"> qui est ä cet effet uruni de Pans (fig. 3), an separe du robinet 1'en- semble de ce Bonnet, de la tige avec son anneau d'etancheite 16 et de 1a, poionee 6; si alors an visse ä fo:nd 1e. Bonnet 4 ä 1'inte- rieur de la poignee 6 (fig.5), 1a paroi de" Forifice 4c monte sur 1e rebord arrondi 14x et sur 1e collet 14, en comprima-nt 1'extremite superieure de la tige, dont 1e diametre peut etre redu.it gräce ä la presence des traits de scie 15. La tige peut alors eire extrafite en 1a tirant vors 1e bas de la. fig.4. Inversement pour 1.e montag,e, la tige munie de 1'anneau 16 est introduite de bas en haut dans 1e bonneu 4 separe de preference de 1a poignee; la rampe 18 de ce Bonnet serre la tige et permet 9a mise en place par 1e jeu des traits de scie 15. La poignee est ensuite vissee sur 1e Bonnet 4, et 1e rebord arrondi 13a, qui termine vors 1e haut 1e eollet 13 permet ä, la tige de s'engagp,r dans la poignde. L'ensemble est alors montul sur 1e corps du robine:t par vissage du Bon net 4. The collar 14 provided for the rod 1 has at its base at 14a a rounded edge which cooperates with the orifice, 4c of the cup 4 to allow the first dismantling of the rod. This disassembly is carried out as follows: by unscrewing the 4RTI Bonnet ID="0003.0274" WI="5" HE="4" LX="1388" LY="614"> which is for this purpose Pans (fig. 3), separates the tap from the whole of this Bonnet, from the stem with its sealing ring 16 and from the handle 6; if then an screw ä fo:nd 1e. Cup 4 inside the handle 6 (fig.5), the wall of the orifice 4c rises on the first rounded rim 14x and on the first collar 14, compressing the upper extremity of the rod, the first diameter can be redu.it thanks to the presence of saw cuts 15. The rod can then be extrafitted by pulling it towards the bottom of Fig. 4. Conversely for 1.e assembly, the rod provided with 1 ' ring 16 is inserted from the bottom upwards into the bonnet 4 preferably separated from the handle, the ramp 18 of this bonnet clamps the rod and allows 9a to be put in place by the play of the saw cuts 15. The handle is then screwed onto the first Cup 4, and the first rounded rim 13a, which ends near the top of the cup 13, allows the stem to engage in the handle.The assembly is then mounted on the first body of the tap by screwing the Bonnet 4.

La vari.ante representee dans la fig.6 differe de la forme d'execution decrite en ce qu -e la. tige est reliee ä la poignee 6 par un filetage 20 de pa.s et sens difArents de ceux du filetage 7, 8, qui relie la poignee au Bonnet 4. Ce filetage 20 peut eire dextrorsum si 1'autre est sinistrorsum ou inversement. De la. sorte, si Von visse sur 1e Bonnet 1a. poignze prealablement vissee sur la tige, la poignee se devisse, de la tige, quo des moyens appro- pries empechent de tourner; res moyens peuvent, par exemple, etre constitues par 1'anneau d'etancheite qui, en serrant la tige, 1'empeche de tourner; la tige se deplace ä chaque tour vers laposition de fermeture du robinet dune quantite egale ä la somme des pa des deux filetages. Inversement, quaud an devisse la, poignee pour ouvrir 1e robinet, la tige so wisse dann 1a poignee. The vari.ante represented in fig.6 differs from the form of execution described in that -e the. rod is connected to the handle 6 by a thread 20 of pitch and direction different from those of the thread 7, 8, which connects the handle to the cup 4. This thread 20 can be dextrorsum if the other is sinistrorsum or vice versa. Of the. so, if Von screws on 1st Cup 1a. handle previously screwed onto the rod, the handle is unscrewed from the rod when suitable means prevent it from turning; res means can, for example, be constituted by the sealing ring which, by tightening the rod, prevents it from rotating; the stem moves with each revolution towards the closed position of the valve by an amount equal to the sum of the pa of the two threads. Conversely, when you unscrew the handle to open the tap, the stem will slide into the handle.

0n pourrait aussi concevoir une variante dann laquelle Beul 1e filet 20 servirait ä 1'ou- verture et ä la fermeture du robinet, quand an ferait tournür la poignee; 1e filetage 7, 8, entre la poignee et 1e bonnet, pourrait alors etre supprime, la poignee ne recevant qu'un mouvement de rotation autour de Faxe de la hge; pour empecher une translation de la poignk parallelement ä Faxe de 1a tige, une liaison par ergot, de preference amovible, et rainure circulaire pourrait alors etre prevue entre la poignee et 1.e bonnet. One could also conceive a variant in which only the thread 20 would be used for opening and closing the tap, when one would turn the handle; the first thread 7, 8, between the handle and the first bonnet, could then be removed, the handle receiving only a rotational movement around the base of the hge; to prevent a translation of the handle parallel to the axis of the rod, a connection by pin, preferably removable, and circular groove could then be provided between the handle and the cup.

Dans la variante repr6sentee par la fig. 7, 1e profil de la rainure compriseentre les collets 13a, et 14a n'est plus re.ctangulair comme preeedemm-ent, mais affecte 1a forme d'un trapeze rectangle. En effet, 1e collet 13ca est oblique et constitue un element flronconi- quce mäle normalement engage contre 1a. partee tronconique femelle 12c quo presente 1e rebord 12 (moitie gauche de 1a fig.7), tandig quo 1e collet 14a. est sensiblement p-er= pendiculaire ä Faxe de la tige. L'extremite superieure de 1a tige est fendue en croix pa.r des traits de scie 15 qui permettent de reduire son diametre pa.r compression, pour Pintro- duire daus 1a poignee, 1'elasdciM de 1a, tige jouant ensuite pour maintenir 1e rebord 12 entre los collets 13a et 14c. In the variant represented by FIG. 7, the first profile of the groove comprisentre the collars 13a and 14a is no longer re.ctangulair as preeedemm-ent, but affects 1a shape of a rectangular trapezium. Indeed, the first collar 13ca is oblique and constitutes a male fronconic element normally engages against 1a. female tapered part 12c quo presents the first edge 12 (left half of 1a fig.7), tandig quo the first collar 14a. is substantially p-er= pendicular to the axis of the stem. The upper end of the rod is split crosswise by saw cuts 15 which make it possible to reduce its diameter by compression, to introduce into the handle, the elasdciM of the rod, the rod then acting to maintain the first rim 12 between the collars 13a and 14c.

Tour demonter 1a, poignee 6, ind6pen- damment de toute autre pike, il ruffit de la devisser des filets 8; des que la tige 1 est arretee dans son mouvement ascendaut par la compression de 1'anneau d'etancheite 16, la portee conique 12a glisse alors sur 1e collet correspondant 13a, ce qui a pour effet de resserrer 1'extremite de la tige (fig. 7 ä droite) f de sorte que la rainure comprise entre 13a et 14a est automatiquement d6ga- gee du rebord 12. Üne simple traction permet d'enlever completement -la poignk 6. Now disassemble the handle 6, independently of any other pike, it suffices to unscrew it from the threads 8; as soon as the rod 1 is stopped in its upward movement by the compression of the sealing ring 16, the conical seat 12a then slides on the first corresponding collar 13a, which has the effect of tightening the end of the rod (fig. 7 on the right) f so that the groove between 13a and 14a is automatically disengaged from the rim 12. A simple pull makes it possible to completely remove the handle 6.

Pour eviter 1e dega.gpment de 1a poignk G en fonctionnement normal, il a ete prevu un verrou qui empeche les branches sepa-rees par los traits de scie 15 de se res-serrer. Ce verrou peut etre un. simple elou enfonce ä. frottement ou une vis vissee au centre de la tige. Los fig. 8 et 9 representent un verrou en forme de eroi.sillon qui se prete au mou@ lage, et dopt les paires de branches 18a et 19n de longueur RTI ID="0004.0276" WI="12"HE="4" LX="1384" LY="474"> inegale, s'engagent dans lcs fentes croisks 15 ä 1'extremite superieure de la tige 1. Les branches les plus longues 19a se terminent par une partie arrondie. 19b, le- gerement en saillie vors 1'exterieur, de sorg qu'elles peuvent s'engager par elasticith sous la paroi interne 6a de la poignee, que Von a partiellement representee en traits mixtes sur la fig. B. Il en resulte quo 1e verrou 18a-19a ne risque par de se degager, ä moins que Von exeroe une certaine traction sur lui. To avoid the first dega.gpment of 1a poignk G in normal operation, a lock has been provided which prevents the branches sepa-rees by los kerfs 15 to res-tighten. This lock can be one. simple elu pushes ä. friction or a screw screwed in the center of the rod. Los fig. 8 and 9 represent a lock in the form of an eroi.sillon which lends itself to mou@ lage, and adopts the pairs of branches 18a and 19n of length RTI ID="0004.0276" WI="12" HE="4" LX=" 1384" LY="474"> unequal, engage in the cross slots 15 at the upper end of the rod 1. The longer branches 19a end in a rounded part. 19b, slightly projecting towards the outside, so that they can engage by elasticity under the internal wall 6a of the handle, which Von has partially represented in phantom in FIG. B. As a result, the latch 18a-19a is unlikely to disengage unless some traction is exerted on it.

La tete 20 du verrou, en forme de galette ä Bord chaufreine 20a, est incisee: de deux encoches 21 diametralement opposees dann lesquelles an peut introduire deux epingles faisant levier en. s'appuyant sur 1e bord 22 de 1'ouverthlre dann la. poigmee 6. The head 20 of the bolt, in the form of a pancake with heated edge 20a, is incised: with two diametrically opposed notches 21 in which an can introduce two pins by levering them. based on the first edge 22 of the dann 1'ouverthlre. handle 6.

La tete du verrou s.ert en meme temps de eaehe-tige et empeche la salete de s'introduire dans les fentes 15, ce qui nuirait au demon- tage facile de la poignee et de la tige. The head of the bolt serves at the same time as a rod sealer and prevents dirt from getting into the slots 15, which would interfere with the easy dismantling of the handle and the rod.

Dann la variante representee dann les fig.10 ä 12, 1e corps 9 du robinet est e:oule d'un scul bloc presentant un logement 2-5 pour 1'anneau d'etancheite et un filetage 23 Sur lequel se wisse plus ou meins 1a poignee. non representee. Ije bonneu 4 preeedemmeni: decrit est alors remplace par un simple krou, pouvant etre wisse daus 1e filetagge interieur 27 et servant ä guider la tige porte-obtura- tour. In the variant represented in Figs. 10 to 12, the first body 9 of the valve is formed of a single block having a housing 2-5 for the sealing ring and a thread 23 On which the handle is wisse more or less. not represented. Ije bonneu 4 preeedemmeni: described is then replaced by a simple krou, which can be threaded daus the first internal thread 27 and serving to guide the shutter holder rod.

Pour permettre 1'.enlevement des noyaux de fonderie, los canaux d'admission 28 et d'ecoulement 29 du liquide ont des sectious de passalte allant en augmentant du centre vers 1'ext4rieur. La cavite mediane 30 a sen- siblement la forme d'un cylindre d'axe, ver- tical, facilement a,ccessible au moulage au ma- ,Ten dun noyait ou d'un mandrin de meme forme qui remplit son vide ainsi qu.e celui de la cavite inferioure 31. Le canal d'ecoul-.- inent 29 est partag6, sur la majeure Partie de sa longueur, en deux eonduits laterau=1 32-33 par une eloison m6diane 34 venue de fonderie avec 1e Corps 9. Cette cloison est obtenue au moyen d'un noyau courbe par tiellement fendu, de section decroissante ä mesure que Fon se rapproche de la cavite mgdiane 30, oiz il se raccorde au noyau cen- tral par deux branches sensiblement pa ralleles. La cloison mediane 34 dont 1'epais- seur diminue de la cavitd centrale 30 vers 1'orifice d'6coulement, sert de brise-jet. To allow removal of the foundry cores, the liquid inlet 28 and outflow 29 channels have passalte sections increasing from the center outwards. The median cavity 30 has substantially the shape of a cylinder with an axis, vertical, easily a, ccessible to molding ma-, Ten dun drowned or a mandrel of the same shape which fills its void as well as. e that of the lower cavity 31. The flow channel 29 is divided, over most of its length, into two lateral conduits=1 32-33 by a median partition 34 coming from the foundry with the 1st Body 9. This partition is obtained by means of a curved core partially split, of decreasing section as it approaches the median cavity 30, where it is connected to the central core by two branches substantially parallel. The median partition 34, the thickness of which decreases from the central cavity 30 towards the flow orifice, serves as a jet aerator.

Une autre forme de brise-jet peut etre realisee au moy en d'un noyau courbe 35 (fig.13) dont 1'extremite la plus kroite pr6- sente une entaille 36 situee dann 1e plan de symUrie du robiinet et une entaille 37 arquee, sensiblement perpendieulaire ä la Premiere. 0n obtient ainsi une croix de matiere mou- 16e, solidaire du Corps de robinet. Another form of aerator can be made by means of a curved core 35 (fig. 13) whose most straight end has a notch 36 located in the first plane of symUry of the valve and an arcuate notch 37 , substantially perpendicular to the Premiere. 0n thus obtains a cross of soft material 16e, integral with the valve body.

Un avantage des robinets selon 1'inven- tion dopt la tige ne tourne pas Pendant la nia.nceuvre de la poignee est qu'ils peuvent comporter -un obturateur .solidaire de la tige. La fig. 14 montre un obturateur conique 38 fixe ä, la-tige 39 et qui peut s'appliquer ä la fois sur un siege supdrieur ä port6e tron- conique 40 et sur un siege infdrieur 41 en Pointe de cöne creux. L'obturateur peut donc avoir n'importe quelle forme ä condition quelle corresponde exactement 5, 1a forme du siege. En particulier, an peut realiser ainsi des ferinetures sur sieges inclines sous des angl.es divers su_r Faxe de 1a tige. An advantage of the taps according to the invention which do not rotate the stem during the operation of the handle is that they can comprise a shutter integral with the stem. fig. 14 shows a conical obturator 38 fixed to the stem 39 and which can be applied both to an upper seat with a frustoconical bearing 40 and to a lower seat 41 with the tip of a hollow cone. The obturator can therefore have any shape provided that it corresponds exactly to the shape of the seat. In particular, an can thus realize ferinetures on inclined seats under various angl.es su_r Faxe 1a rod.

Un autre avantage des robinets selon Fin- v ention rAide dans le fait que 1e serrage de Fanneau d'etanch6ite pourra se borner 5: une simple compression 61astique transver- sale, Pvitant des efforts incompatibles avec 1a r4istance des organes en mauere plas- tique. La suppression du presse-6toupe ordi- naire constitue donc un progres, outre quelle permet de simplifier la fabrication du ro- binet. Another advantage of the taps according to the invention is that the tightening of the sealing ring can be limited to 5: a simple transverse elastic compression, avoiding efforts incompatible with the resistance of the plastic bodies. The elimination of the ordinary cable gland therefore constitutes progress, in addition to which it makes it possible to simplify the manufacture of the valve.
