Patent Images
1. A tire valve assembly comprising a hollow unitary stem member;
- means surrounding said stem member for mounting said stem member within a rim hole of a vehicle wheel with the stem member extending outward of the rim, an elongated member received within said stem member, a seal element formed on said elongated member as an integral part thereof and sealingly engageable with a portion of said stem member to prevent the passage of air through said stem member, an actuating pin element formed on said elongated member as an integral part thereof and engageable by means external to said stem member to move said elongated member to a position wherein said seal element is out of engagement with said portion of said stem member, a retainer received within said stem member, and a compression spring acting between said retainer and said elongated member, said elongated member being formed of an elastomeric material with a hardness of between 40 and 80 durometer when subjected to ASTM Test D-2240, a tensile strength of at least 3000 psi when subjected to ASTM Test D-412, and a Bashore resilience of at least 48 percent.
