Abstract
A valve for removable attachment to the rim of a heavy-vehicle tubeless t includes a valve base, a locking nut and a sealing joint. The valve base has a tubulure that passes through an opening in the rim, a shoulder for compressing the sealing joint against one surface of the rim and two diametrically opposite resting surfaces for engaging the rim surface and limiting the compression of the sealing joint. The locking nut cooperates with the opposite surface of the rim to compress the sealing joint against the rim.
Claims9
A valve intended to be removably attached to a rim for heavy-vehicle tubeless tires, passing through a valve hole, in which the means for a tight fastening to the rim comprise:
- a sealing joint,
- a valve base with a tubulure intended to pass through the valve hole, said tubulure having a shoulder perpendicular to the axis of said tubulure and forming a first resting surface against a first surface of said rim, said shoulder having means for maintaining the sealing joint,
- locking means forming a second resting surface against a second surface of said rim and cooperating with said tubulure in order axially to compress said sealing joint between said shoulder and said first surface of the rim,
- characterized by the fact that said first resting surface is formed of two diametrically opposite resting zones.
A valve intended to be removably attached to a rim for a heavy-vehicle tubeless tire, passing through a valve hole in the rim, comprising:
- a valve base having a tubulure intended to pass through the valve hole,
- an annular seal intended to be interposed between the valve hole and the tubulure and to engage a surface of the rim surrounding the valve hole,
- said tubulure having a shoulder for compressing the annular seal against the surface of the rim surrounding the valve hole and having two diametrically opposite extensions for engaging the rim surface beyond the outer periphery of the seal to limit the compression of the seal, and
- locking means engageable with the opposite surface of the rim surrounding the valve hole for locking the tubulure on the rim in sealed condition.
