Abstract
Flatproofing liquid is provided to tires through a one-way disposable valve assembly. In accordance with the method, the valve stem core is removed from the tire to allow the liquid to be freely admitted. A one-way valve is attached to the valve stem, and the tire is filled with the flatproofing material. The flatproofing material is then allowed to cure in the tire and in the valve. After curing, the valve is removed and discarded. The apparatus includes an inexpensive one-way valve for connection to the valve stem at one end and supply hoses at the other.
Claims2
In combination, a valve assembly for use in flatproofing a tire equipped with a tire stem, and a source of flatproofing liquid reactants that will cure inside said tire to produce a cured polymeric mass, wherein said valve assembly comprises:
- one-way valve means for providing a one-way flow of said flatproofing liquid reactants from an inlet to an outlet and having a housing;
- connecting means consisting essentially of an opening in said housing for connecting said outlet of said valve means to said tire stem;
- and
- attaching means for removably attaching said inlet of said valve means to said source of flatproofing liquid reactants.
