Abstract
A valve of the “Snap-In” type is intended to be mounted directly on the rim of a vehicle wheel fitted with a “tubeless” tire. The valve is secured to the rim through which it passes via a groove produced at the base of a bulb extended by a rubbery coating of an internal nozzle of the valve. The groove collaborates elastically with a hole in the rim, on the periphery of which hole it becomes lodged, the mass or the volume of the bulb being smaller in its region (A) toward the interior of the rim by comparison with its region (B) directed toward the exterior, this reduction taking place near the groove intended to collaborate with the hole in the rim, both in the part thereof that surrounds the nozzle and in the part thereof that is in contact with the bottom of the rim.
Claims4
A valve of a snap-in type intended to be mounted directly on a rim of a vehicle wheel fitted with a tubeless tire;
- said valve being secured to a hole in the rim through which the valve passes axially by the intermediary of a groove, produced at a base of a bulb of the valve, said bulb extended by a rubbery coating of an internal nozzle of the valve;
- said groove cooperating elastically with the hole in the rim, on the periphery of which said groove becomes housed, according to a longitudinal axis XX′ of the valve, a reduction of the bulb being created by reducing the mass or the volume of the bulb, consequently lower, in a region of the bulb located under said longitudinal axis, directed toward an interior of the rim, consequently different by comparison with a region of the bulb located above the said longitudinal axis, toward an exterior of the rim, in order to define an asymmetric valve;
- said reduction of the bulb taking place in the vicinity of the groove, intended to cooperate with the hole in the rim;
- and said valve comprising means of indexing in such a way as to direct said reduction toward a bottom of the rim.
