ABSTRACT:
A clamp-in valve for a road vehicle which can be inserted and removed from the outside of the wheel instead of from the inside consists of a valve stem flanged at one end with a rubber grommet at that end, the grommet being flanged at its end remote from the valve stem flange, and retaining means for pressing on the flange of the grommet. The diameter of the flange of the valve stem is smaller than the diameter of the aperture of the wheel into which the valve is to be inserted. The retaining means can be washer and nut or a lock washer engaging in a groove or rib of the valve stem and held by, for example, a screw-on dust cap with an elongate skirt. The flanged end of the valve stem is inserted through the wheel aperture and the retaining means tightened so that the rubber grommet is compressed to seal and clamp the valve stem in the aperture. The valve may be used with tubeless tires or tubed tires having a modified rubber spud for attachment to the tube.
