En figure 3 on représente un piston classique de ce type qui comprend: un piston 4 en matériau plastique comportant des extrémités d'étanchéification 3, chanfreinées, ressemblant à un cylindre, lesquelles sont montées en étant inclinées sur la face circonférentielle de la chambre cylindrique 2 d'un réservoir 1 de sorte qu'elles peuvent s'étendre latéralement et coulisser le long de chaque face circonférentielle de la chambre définie soit à l'avant ou à l'arrière dans le sens axial représenté par une flèche, et une plaque métallique 5 fixée à l'arrière du piston 4, dont les extrémités d'étanchéification sont placées sur la face circonférentielle de la chambre de  FIG. 3 shows a conventional piston of this type which comprises: a piston 4 made of plastic material having sealing ends 3, chamfered, resembling a cylinder, which are mounted by being inclined on the circumferential face of the cylindrical chamber 2 of a reservoir 1 so that they can extend laterally and slide along each circumferential face of the defined chamber either at the front or at the rear in the axial direction represented by an arrow, and a metal plate 5 fixed to the rear of the piston 4, the sealing ends of which are placed on the circumferential face of the

façon à rendre le piston 4 exempt de rétrogression.  so as to make the piston 4 free of retrogression.

Le piston classique auquel est fixée la plaque métallique 5 s'est avéré présenter l'inconvénient d'un coût de fabrication élevé à cause du grand nombre d'étapes d'assemblage et des pièces et composants. Ce qui est encore plus désavantageux est le fait que la plaque métallique 5 provoque l'éraflure de la surface intérieure de la chambre cylindrique 2, ce qui ne permet de réutiliser le réservoir 1. La présente invention a pour objet la fabrication à un coût raisonnable d'un piston se montant à l'intérieur d'un instrument de peinture pour pousser un fluide, tout en ne pouvant reculer à l'intérieur d'un réservoir en l'absence d'un - accessoire tel que la plaque métallique 5 et avec une faible probabilité de créer des  The conventional piston to which the metal plate 5 is fixed has been found to have the disadvantage of a high manufacturing cost because of the large number of assembly steps and of the parts and components. What is even more disadvantageous is the fact that the metal plate 5 causes the scratching of the interior surface of the cylindrical chamber 2, which does not allow reuse of the reservoir 1. The present invention relates to the manufacture at a reasonable cost a piston mounted inside a painting instrument to push a fluid, while not being able to move back inside a tank in the absence of an accessory such as the metal plate 5 and with a low probability of creating

éraflures dans la chambre cylindrique du réservoir.  scratches in the cylindrical chamber of the tank.

Le dispositif de guidage comporte une tige filetée 9 fixée perpendiculairement à l'arrière du piston 6 et ne pouvant tourner qui est insérée dans un trou 11 de forme carrée ménagé dans une butée 10. La tige 9 au filetage hélicoïdal est montée dans un cylindre hélicoïdal 12 de manière à être entraînée vers l'avant par la manipulation d'un moyen tournant 13 dont la rotation est  The guide device comprises a threaded rod 9 fixed perpendicularly to the rear of the piston 6 and which cannot rotate which is inserted into a square-shaped hole 11 formed in a stop 10. The rod 9 with a helical thread is mounted in a helical cylinder 12 so as to be driven forward by the manipulation of a rotating means 13 whose rotation is

transformée en mouvement vers l'avant de la tige à travers  transformed into forward movement of the rod through

le cylindre 12, d'o le guidage du piston 6 vers l'avant.  the cylinder 12, from which the piston 6 is guided forward.

Cependant, le piston de la présente invention peut être conçu pour fonctionner avec n'importe quel type de dispositif de guidage. Le piston 6 moulé en polyéthylène comporte, comme représenté en figure 2, des extrémités d'étanchéification, chanfreinées, ressemblant à un cylindre, 3 et 3a, qui sont montées en étant inclinées sur la face circonférentielle de la chambre cylindrique 2 d'un réservoir 1 de sorte qu'elles peuvent s'étendre latéralement et coulisser le long de chaque face circonférentielle de la chambre définie soit à l'avant soit à l'arrière dans le sens axial, un angle d'environ 120 étant formé avec la face axialement intérieure de l'extrémité arrière 3a et avec la face circonférentielle de la chambre 2 du réservoir 1. L'angle a peut être choisi  However, the piston of the present invention can be designed to operate with any type of guide device. The piston 6 molded in polyethylene comprises, as shown in FIG. 2, sealing ends, chamfered, resembling a cylinder, 3 and 3a, which are mounted by being inclined on the circumferential face of the cylindrical chamber 2 of a reservoir. 1 so that they can extend laterally and slide along each circumferential face of the defined chamber either at the front or at the rear in the axial direction, an angle of approximately 120 being formed with the face axially inside of the rear end 3a and with the circumferential face of the chamber 2 of the tank 1. The angle a can be chosen

arbitrairement à une valeur comprise entre 90 et 135 .  arbitrarily at a value between 90 and 135.

Avec une telle valeur de l'angle, les pointes, en particulier, des extrémités coulissantes 3 et 3a sont amenées à s'étendre latéralement sous l'effet du frottement produit lorsque le fluide 7 est pressurisé par le mouvement vers l'arrière, entre les pointes des extrémités 3 et 3a et la face circonférentielle du réservoir 1, de sorte que le piston agit pour éviter de reculer par l'effet d'une force produite par les pointes des extrémités coulissantes qui  With such an angle value, the tips, in particular, of the sliding ends 3 and 3a are caused to extend laterally under the effect of the friction produced when the fluid 7 is pressurized by the backward movement, between the tips of the ends 3 and 3a and the circumferential face of the tank 1, so that the piston acts to avoid backing up by the effect of a force produced by the tips of the sliding ends which

compriment la face circonférentielle du réservoir 1.  compress the circumferential face of the reservoir 1.

Lorsque la valeur de l'angle est à l'extérieur de la plage -135 , la force agissant sur les pointes des extrémités coulissantes pour les étendre latéralement est si faible que les pointes ne peuvent que coulisser le long de la face circonférentielle du réservoir 1 et le piston 7 peut difficilement ne pas reculer. Il n'est pas nécessaire que  When the angle value is outside the range -135, the force acting on the tips of the sliding ends to extend them laterally is so weak that the tips can only slide along the circumferential face of the tank 1 and the piston 7 can hardly not move back. It is not necessary that

le piston soit constitué d'un matériau spécial.  the piston is made of a special material.

La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, elle est au contraire susceptible de modifications et de  The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and
