Title (EN) TYRE INFLATION GUN
(FR) PISTOLET DE GONFLAGE POUR PNEUS
Abstract:
(EN) A tyre inflation pistol comprises a high pressure supply side (22), a passageway (28) leading to a pressure gauge, a passageway (26) leading to the tyre and a valve assembly. The valve assembly is arranged to close off the gauge passageway (28) when the tyre is being inflated to prevent damage to the gauge. The valve assembly comprises: a first valving element (14, 32) which controls air flow from the high pressure supply (22) to the tyre side (26); a second valving element (40, 42, 44, 46, 48) which slides in an axial hole (26) in the first valving element and acts to close off an aperture (54) leading to the pressure gauge; and an operating lever (18). Initially, the tyre side (26) of the valve is connected to the pressure gauge side (28) via an aperture (54). Operating the lever (18) moves the second valving element (42, 46) to close off the aperture (54). Further movement of the lever (18) pushes the head (48) of the second valving element against the first valving element (14) and opens the high pressure supply side (22) to the tyre side (26).
(FR) Ce pistolet de gonflage pour pneus comprend un côté d'alimentation haute pression (22), un passage (28) conduisant à un manomètre, un passage (26) conduisant au pneu et un ensemble soupape, lequel est conçu, lorsque l'on gonfle le pneu, pour fermer le passage (28) vers le manomètre, afin d'empêcher l'endommagement de celui-ci, et comporte: un premier élément de fermeture (14, 32) commandant l'écoulement d'air entre l'alimentation (22) haute pression et le côté pneu (26), un second élément (40, 42, 44, 46, 48) de fermeture, lequel coulisse dans un alésage axial (26) ménagé dans le premier élément de fermeture et agit pour fermer une ouverture (54) conduisant au manomètre, ainsi qu'un levier de commande (18). Dans un premier temps, le côté pneu (26) de la soupape est relié au manomètre (28), via un orifice (54). Puis, l'actionnement du levier (18) provoque le déplacement du second élément de fermeture (42, 46), afin de fermer l'orifice (54). Un autre déplacement du levier (18) a pour effet de pousser la tête (48) du second élément de fermeture contre le premier élément (14) et d'ouvrir le côté (22) permettant l'alimentation haute pression vers le côté pneu (26).
