Abstract

Vanne et système d’application de produit de revêtement comprenant une telle vanne Cette vanne (4) comprend un corps (8) comprenant un orifice central interne (10) et une chambre (12), la vanne comprenant également un piston (24) formé par une tige (240) par une tête de piston (242) montée dans la chambre (12), la tige (240) se prolongeant hors du corps (8) et étant destinée à se déplacer dans un alésage (6) du système d’application (2). La vanne comprenant un premier dispositif d’étanchéité (26) logé dans le corps (8) autour de la tige de piston (240) d’un côté de la vanne où la tige de piston se prolonge hors du corps (8), une partie (12A) de la chambre (12) étant destinée à être remplie d’un fluide de commande sous pression (F2) de manière à obtenir, à l’encontre de l’effort d’un ressort (34) logé dans le corps (8), le déplacement (F3) du piston (24). La vanne comporte un second dispositif d’étanchéité (38) logé dans le corps (8) autour de la tige de piston (240) entre le premier dispositif d’étanchéité (26) et la chambre (12). La vanne comprend un conduit d’évent (40) prévu dans la tige du piston (240) et communicant avec l’orifice central interne (10) entre le premier dispositif d’étanchéité (26) et le deuxième dispositif d’étanchéité (38) et débouchant à l’air libre ou dans une partie (12B) de la chambre (12) communiquant avec l’air libre. Figure pour l'abrégé : Figure 1Valve and coating product application system comprising such a valve This valve (4) comprises a body (8) comprising an internal central orifice (10) and a chamber (12), the valve also comprising a piston (24) formed by a rod (240) by a piston head (242) mounted in the chamber (12), the rod (240) extending outside the body (8) and being intended to move in a bore (6) of the system of application (2). The valve comprising a first sealing device (26) housed in the body (8) around the piston rod (240) on one side of the valve where the piston rod extends out of the body (8), a part (12A) of the chamber (12) being intended to be filled with a pressurized control fluid (F2) so as to obtain, against the force of a spring (34) housed in the body (8), the displacement (F3) of the piston (24). The valve has a second sealing device (38) housed in the body (8) around the piston rod (240) between the first sealing device (26) and the chamber (12). The valve comprises a vent conduit (40) provided in the piston rod (240) and communicating with the internal central orifice (10) between the first sealing device (26) and the second sealing device (38 ) and opening into the open air or into a part (12B) of the chamber (12) communicating with the open air.
