<p>The disclosed tire valve includes an elastic valve body having a through passageway formed therein, with a constriction formed at an intermediate portion of the through passageway. A valve pin is provided with a gasket and is mounted to slide within the through passageway. A spring is positioned between the pin and the valve body to bias the pin to a sealing position. Preferably, the pin is formed of an elastic material. The valve body defines a sharp edged step adjacent to the constriction and the valve pin defines a sharp edged flange positioned to abut the step in the valve body so as to increase the bursting pressure of the valve.</p> |
