Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
A tire valve comprising a rigid tubular body having an enlarged base and formed with a groove spaced from the base, gasket means having an annular flange portion and a tapered longitudinal extension surrounding the body adjacent the base, and an annular spring C-shaped clip surrounding and engaging the body in the groove and having a plurality of straight tapered spring fingers narrowing as their distal ends are approached extending outward and generally toward the base, whereby the valve can be inserted into a rim hole opening, smaller end first, so that the fingers flex inward toward the center of the valve until they are through the opening and then spring outward to trap the valve in the opening with the gasket in compressive sealing relation to the rim.
