Abstract
Apparatus for filling a vehicle tire with a reactive liquid elastomer which when cured results in a flat-free tire. The apparatus provides for pre-filling the tire with air of desired pressure to properly set the tire bead on its rim and to maintain such tire pressure during the liquid filling operation. The apparatus enables removal of residual air within the tire as the tire is being filled with liquid and also indicates when the tire is completely filled with such liquid.
Claims5
An air release regulator for controlling the escape of air from a pneumatic tire while the tire is being inflated and filled with a liquid resin that subsequently cures to form a solid elastomeric filling, said tire being mounted on a wheel rim having a tire valve through which air and liquid resin are injected into the interior of the tire, said air release regulator comprising, in combination:
- a body having an internal passageway provided therein;
- a hollow needle connected to said body and communicating with said internal passageway, said needle being adapted to pierce and penetrate the tread rubber on the tire;
- a spring-loaded pressure-relief valve disposed within said internal passageway, so as to allow air within the tire to escape when the internal pressure exceeds a predetermined limit;
- a vent opening extending from said internal passageway outwardly of said check valve, so as to allow air and liquid resin to escape from the tire;
- and
- a cup attached to said valve body to catch liquid resin escaping from said vent opening.
