La demande de brevet PCT/CH97/00316 présente une tête de pulvérisation pour pistolet de pulvérisation à haute pression, comprenant un élément de forme cylindrique monté rotatif dans un corps central et traversé par un conduit principal à l'extrémité duquel est montée une buse de pulvérisation envoyant un jet de fluide à haute pression sous forme de fuseau, deux canaux d'air à base pression se prolongeant à partir du corps central à l'intérieur de l'élément de forme cylindrique, de part et d'autre du conduit central de la buse, les orifices de sortie des jets d'air dans l'élément de forme cylindrique étant décalés par rapport aux orifices d'entrée en communication avec les canaux du corps central.Patent application PCT / CH97 / 00316 presents a head for spray for high spray gun pressure, comprising a cylindrical element mounted rotating in a central body and traversed by a conduit main at the end of which is mounted a nozzle spray sending a high pressure fluid jet in the form of a spindle, two air channels based on pressure extending from the central body inside the cylindrical element on either side of the central duct of the nozzle, the outlet ports of the jets of air in the cylindrical element being offset by relative to the entry ports in communication with the central body canals.
La demande de brevet PCT/CH98/00104 présente une tête de pulvérisation pour pistolet de pulvérisation à haute pression comprenant un élément rotatif placé dans un corps central et traversé par un canal présentant un orifice de pulvérisation et un joint assurant l'étanchéité entre l'élément rotatif et le pistolet, l'élément rotatif présente dans sa partie centrale une forme sphérique apte à collaborer avec le joint placé à l'intérieur du corps central et deux sièges circulaires placés de part et d'autre de la partie sphérique prenant appui sur les sièges placés de part et d'autre du corps central.Patent application PCT / CH98 / 00104 presents a head for spray for high spray gun pressure comprising a rotary element placed in a body central and crossed by a channel having an orifice spray and a seal ensuring the seal between the rotating element and the gun, the rotating element has in its central part a spherical shape suitable for collaborate with the seal placed inside the body central and two circular seats placed on either side on the other side of the spherical part resting on the seats placed on either side of the central body.
Les têtes de pulvérisation connues dans l'art antérieur présentent le désavantage d'avoir la fente de la buse à un niveau sensiblement égal ou inférieur au sommet de la tête de pulvérisation, ce qui produit toujours des interférences à la sortie du jet de fluide. En plus de cela, au moment d'arrêter la prestation, le liquide qui n'a pas pu quitter le pistolet retombé autour de la buse et par conséquent l'utilisateur est dans l'obligation permanent de la nettoyer pour éviter l'accumulation de peinture sèche autour de la fente de la buse et sur le sommet de la tête de pulvérisation. Le problème devient encore plus aigu lorsque l'on utilise des têtes de pulvérisation avec jets d'air additionnel, car les jets d'air provoquent des turbulences créant des dépôts de sédimentation de fluide sur le sommet de la tête. Ces dépôts sont particulièrement gênants, car ils donnent naissance à des gouttelettes, qui peuvent être projetées sur les objets à traiter par les jets d'air.Spray heads known in the prior art have the disadvantage of having the nozzle slot at a level substantially equal to or lower than the top of the head spraying, which always produces interference at the outlet of the fluid jet. On top of that, at the time to stop the service, the liquid which could not leave the gun dropped around the nozzle and therefore the user is under the permanent obligation of the clean to prevent dry paint buildup around the nozzle slot and on the top of the head spray. The problem becomes even more acute when using spray heads with jets additional air because the air jets cause turbulence creating fluid sedimentation deposits on the top of the head. These deposits are particularly bothersome because they give rise to droplets, which can be projected onto the objects to be treated by air jets.
Le but de la présente invention est de remédier à ces inconvénients et de proposer une tête de pulvérisation, notamment pour pistolet de pulvérisation à haute pression comprenant un élément rotatif placé dans un corps central et traversé par une buse de pulvérisation et un joint assurant l'étanchéité entre l'élément rotatif et le pistolet, l'élément rotatif présentant une partie centrale circulaire comprenant la buse et introduite dans une ouverture latérale du corps central, caractérisée en ce que la partie centrale circulaire est amenée par une translation vers le haut du corps central dans une position de travail contre au moins une butée intérieure située au sommet du corps central, la buse placée dans la partie circulaire de l'élément rotatif étant dans la position de travail au dessus du sommet du corps central.The object of the present invention is to remedy these disadvantages and to propose a spray head, especially for high pressure spray gun comprising a rotary element placed in a central body and crossed by a spray nozzle and a seal ensuring the seal between the rotary element and the pistol, the rotating member having a circular central part comprising the nozzle and introduced into a lateral opening of the central body, characterized in that the circular central part is brought by a translation up the central body in a working position against at least one inner stop located at the top of the central body, the nozzle placed in the circular part of the rotary element being in the working position at above the top of the central body.
Avec la possibilité d'amener la partie centrale circulaire vers le haut de la tête par une translation, la buse placée sur la partie centrale pourra être surélevée et sortir du sommet de la tête. Ainsi, l'accumulation de peinture sur l'appareil lors de l'utilisation sera limitée, de même que les dépôts résiduels du fluide susceptibles de provoquer des souillures sur les pièces à gicler ou à revêtir.With the possibility of bringing the circular central part towards the top of the head by a translation, the nozzle placed on the central part can be raised and come out of the top of the head. Thus, the accumulation of paint on the device during use will be limited, as will residual deposits of the fluid likely to cause soiling on parts to be sprayed or coated.
Avec la disposition proposée selon l'invention, la buse pourra être amenée à dépasser la hauteur du sommet de la tête d'une distance de 1 à 5 mm.With the arrangement proposed according to the invention, the nozzle may have to exceed the height of the top of the head from a distance of 1 to 5 mm.

l'élément rotatif 3 se trouve un insert ou buse de
pulvérisation en carbure de tungstène 37 et une vis creuse
39, qui serre l'insert 37, par l'intermédiaire d'un joint
torique 38, qui est placé entre la buse et la vis qui
présente un alésage central non représenté et est serrée à
l'aide d'une clef à six pans. La fente de l'insert 37 est
placée dans le sens de l'axe de l'élément rotatif 3.Inside the central part 31 (FIG. 3) of
the
Le corps central 2 (figures 4 et 5) présente une ouverture
latérale 21 qui se prolonge vers le haut par une rainure
22, une deuxième ouverture latérale 21a d'une dimension
plus petite se trouvant du côté opposé à la première et se
prolongeant également par une rainure comme dans le cas de
l'ouverture latérale 21. Deux ergots 23 sont placés au
sommet du corps central, chacun présentant un orifice de
sortie 25 en direction de l'axe du corps central et
sensiblement-perpendiculaire à celui-ci. Ces orifices 25
sont en communication avec deux canaux 24, qui traversent
la paroi du corps central dans le sens de son axe et qui
sont sensiblement perpendiculaires aux orifices de sortie
25. Ces canaux 24 sont destinés à envoyer un flux d'air
vers le sommet de l'insert de pulvérisation 37 à la base du
jet. Leurs orifices de sortie 25 peuvent être remplacés par
des fentes. D'autres canaux 28 traversent les parois du
corps central 2 dans la direction de son axe pour accéder
aux orifices respectifs de sortie 29 (figures 6 et 7)
placés au sommet du corps central et qui forment un angle
aigu avec le fuseau qui sort par la fente de la buse. Ces
quatre orifices 29 sont destinés à envoyer un flux d'air
qui permet de changer l'angle de pulvérisation. A
l'intérieur de chacun de ces canaux 28 et à leur base, est
prévu un filetage 28a, qui permet l'introduction avec une
clef à six pans des vis 28b, qui sont utilisées comme
étrangleurs d'air. Elles se présentent sous forme de vis
creuses avec des diamètres d'alésage différents dans le but
de varier le débit d'air. Toutes les vis 28b d'un même jeu
ont le même diamètre d'alésage. Il est évident que les
canaux 24 peuvent également être munis des vis creuses 28b
servant au réglage du débit d'air.The central body 2 (Figures 4 and 5) has an opening
lateral 21 which is extended upwards by a
Dans la partie inférieure, le corps central 2 présente une
rainure sous forme de couronne circulaire 27 collaborant
pour la liaison avec le pistolet et permettant le passage
de l'air à basse pression aux canaux 24,28. Généralement,
les pistolets utilisés en liaison avec la buse de
pulvérisation qui vient d'être décrite présentent un
réglage d'air comprimé qui sera amené dans la rainure
annulaire 27. Le réglage des débits d'air comprimé des
orifices 25, respectivement 28 sera déterminé par le choix
des alésages des vis creuses 28b. Il existe sur le marché
des modèles de pistolets avec deux réglages d'air
différents. Dans ce cas il sera possible d'alimenter
séparément les canaux 24 et les orifices 25 qui débouchent
sur les ergots et les autres canaux 28 et leur orifices
respectifs 29. In the lower part, the
En fonctionnement, l'élément rotatif 3 est introduit dans
le corps central 2 à travers l'ouverture 21, le disque
tronqué 33 de diamètre supérieur à l'ouverture 21 fixe la
position jusqu'à laquelle l'élément rotatif 3 peut être
introduit. Le disque 35 va sortir par l'autre côté du corps
central 2 à travers l'ouverture 21a. A ce moment, les
épaulements 32,32a peuvent glisser tout au long des
rainures 22 vers le haut du corps central 2 jusqu'à ce que
lesdits épaulements 32 heurtent la partie supérieure des
encoches 22. L'élément rotatif 3 est alors situé au sommet
du corps central 2 et la buse de pulvérisation 37 se trouve
au dessus dudit sommet. Le joint 4 coulisse à l'intérieur
de l'alésage 30 du corps central 2 pour assurer
l'étanchéité entre celui-ci et le pistolet non représenté
dans le dessin. La saignée 41 du joint cylindrique 4 assure
une plus grande étanchéité puisque la partie centrale 31 de
l'élément rotatif 3, sous forme de bille dans le dessin
repose sur les deux arêtes de la saignée 41. Pour mieux
assurer cette étanchéité, le joint cylindrique 4 présente à
sa base le joint d'extrémité 5 en plastique polyamide
(nylon) qui va relier la tête 1 au pistolet et le joint
« O-Ring » 6 en Viton qui collabore avec le corps central 2
à l'intérieur de son alésage 30.In operation, the
Quand la tête de pulvérisation 1 est dans sa position de
travail comme montré dans la figure 1, le fluide à haute
pression arrive par les alésages 7a,7 et continue son
chemin à travers la vis 39 et la buse 37 reliés par le
joint torique 38 en téflon. Le fluide qui va sortir sous
forme de fuseau par là buse de pulvérisation 37 peut être
réglé avec l'adjonction de l'air à base pression par le
moyen des deux séries de canaux (24,28) qui vont dans la
direction de l'axe du corps central et à l'intérieur de ses
parois. L'air sous pression parcourt les deux canaux 24 en
provenant de la rainure 27 à la base du corps central 2 et
parvient aux orifices 25 de sortie, qui forment un angle
sensiblement droit avec les canaux, l'air à base pression
étant projeté sensiblement perpendiculairement contre le
fuseau de fluide à haute pression qui sort par la fente de
la buse 37 renforçant par cet apport d'air l'atomisation
dudit fuseau de fluide. De même l'air à basse pression
arrive aux canaux 28 qui partent aussi de la base du corps
central 2 et parcourt l'intérieur des parois dudit corps
central 2 pour arriver aux orifices 29 qui ont une
inclinaison par rapport aux canaux 28. L'air à base
pression traverse les canaux 28 et sort d'un coté et de
l'autre de la buse 37 en formant un angle aigu avec le
conduit central de la buse 37, de manière à pouvoir régler
l'angle d'ouverture du fuseau de fluide qui sort par la
buse 37.When the
A l'aide de la poignée 35, l'élément rotatif peut tourner
de 180° et la buse 37 est alors placée de manière que sa
fente soit confrontée à la sortie de l'alésage 7, prête
pour son nettoyage. Cette opération est très simple puisque
la goupille 34 va buter contre les rebords 26 de
l'évidement 34a dans les deux positions opposées plaçant
avec précision l'élément rotatif 3 en chaque cas.Using the
La variante de la tête représentée dans les figures 8 à 11
comprend un corps central 2 traversé par un élément rotatif
ou clef identique non représenté à l'élément 3 du mode
d'exécution des figures 1 à 7 et muni d'un joint également
non représenté identique au joint 4 des figures 1 à 7. Dans
les figures 8 à 11, il a été représenté uniquement le corps
central 2, étant entendu que tous les éléments constituant
le corps central, ainsi que tous les éléments constituant
la tête 2 et contribuant au fonctionnement de celle-ci sont
les mêmes que ceux du mode d'exécution des figures 1 à 7.The variant of the head shown in Figures 8 to 11
includes a
On retrouve ainsi sur la tête 2 des figures 8 à 11
l'ouverture latérale 21 se prolongeant vers le haut par une
rainure 22 permettant à l'élément rotatif ou clef 3 d'être
introduit dans la tête 2 et amené dans la position de
travail par une translation vers le haut dans la rainure
22, comme représenté dans la figure 11. Les deux ergots 23
placés au sommet de la tête 2 présentent également
l'orifice de sortie 50 qui se présente dans la variante
sous forme d'une fente dirigeant l'air additionnel
d'atomisation sous un angle d'approximativement 12° par
rapport à l'axe de la tête. Cet angle de 12° peut bien
évidemment varier dans une fourchette allant de 0 à 20° si
l'on veut attaquer le jet à la sortie de la buse ou un peu
plus haut. Cet angle dépendra également de la hauteur entre
le haut de la buse et le sommet de la tête, qui elle sera
située dans une fourchette de 1 à 5 mm.We thus find on the
Comme dans le mode d'exécution des figures 1 à 7, les
orifices d'atomisation 50 sont alimentés par les canaux 24
identiques à ceux du mode d'exécution des figures 1 à 7.As in the embodiment of Figures 1 to 7, the
Toujours comme dans le mode d'exécution des figures 1 à 7,
les canaux 28 (figure 8 et 11) sont en liaison avec les
orifices de sortie-29 débouchant au sommet de la tête 2.
Dans la variante représentée les orifices de sortie 29 sont
au nombre de deux ; il peuvent cependant être plus
nombreux, par exemple 4 ou 6. Ces orifices de sortie 29
sont, comme dans le mode d'exécution des figures 1 à 7
destinés à l'air additionnel ouvrant plus ou moins le
faisceau du jet principal. Dans le cas où ils sont au
nombre de 4 ils déboucheront de part et d'autre de l'axe
XI-XI de la coupe de la figure 11. Dans le cas où il y a 6
canaux, ils seront placés de part et d'autre des canaux 28
de la figure 8. Comme représenté dans la figure 11, les
orifices de sortie 29 feront un angle avec l'axe vertical
de la tête variant dans une fourchette de 45 à 60°. Dans la
variante de la figure 11, l'angle est de 50°.Still as in the embodiment of Figures 1 to 7,
the channels 28 (FIGS. 8 and 11) are linked to the
outlet ports-29 opening at the top of the
Finalement, dans la variante des figures 8 à 11, l'élément
rotatif ou la clef 3 est introduit dans des ouvertures
latérales 21 de la tête 2 formant un axe de 45° (axe IX-IX
de la coupe de la figure 9) par rapport aux deux ergots 23
(ligne X-X- de la figure 8). Ainsi, la buse 51 (figure 8)
sera placée à 45° par rapport à l'axe de l'élément rotatif
ou clef 3. Cette disposition est avantageuse par le fait
qu'elle permet une répartition plus aisée des canaux d'air
additionnel et par là une fabrication plus simple de la
tête.Finally, in the variant of Figures 8 to 11, the element
rotary or key 3 is inserted into
Le mode d'exécution des figures 1 à 7, de même que la
variante des figures 8 à 11 comprend un élément rotatif se
présentant sous forme d'une bille partiellement introduite
dans une partie en forme d'entonnoir placée à l'intérieur
du joint 4. Comme mentionné plus haut, une saignée 41 est
placée sur le pourtour de l'entonnoir à l'endroit où_la
surface sphérique de la bille 31 est en contact avec
l'intérieur du joint. Cette saignée 41 peut être réalisée
par usinage, moulage ou en repoussant la matière dudit
joint. Alternativement, la saignée 41 peut être remplacée
par une recouvrement se présentant sous la forme d'une zone
circulaire 41a incrustée à l'intérieur du cône, la zone 41a
étant en contact avec la bille de l'élément rotatif. The embodiment of Figures 1 to 7, as well as the
variant of FIGS. 8 to 11 comprises a rotary element
in the form of a partially introduced ball
in a funnel-shaped part placed inside
of the
Bien que le mode d'exécution et la variante qui viennent
d'être décrit présentent tous deux un élément rotatif ou
clef 3 comprenant une bille 31 placée entre les deux axes
32 et 32a, il est évident que l'invention n'est pas limitée
à cette solution et que la bille peut être remplacée par un
cylindre ou une surface circulaire concave. Le joint 4 sera
alors adapté à cette surface par tout moyen connu de
l'homme de métier.Although the method of execution and the variant which come
to be described both have a rotary element or
key 3 comprising a
Le corps central 2 est réalisé en aluminium éloxé ; il peut
cependant être fabriqué en acier inox, en acier chromé ou
en matière plastique renforcée avec par exemple des fibres
de carbone.The
De même l'élément rotatif 3 et le joint 4 pourront être
réalisés en métal, en matière plastique renforcée ou en
céramique.Similarly, the
