Abstract
A springless valve having a valve body, a valve stem insert, and an O-ring gasket for sealing the insert to a valve seat of the valve body. As the valve stem insert rotates about its axis, fingers on vanes of the insert move within threads of the valve body, and the insert moves between valve-opened and valve-closed positions. A coupling engages with the valve body during inflation/deflation and, as the coupling rotates with respect to the valve body, it engages the insert for mutual rotation to move the insert between the valve-opened and valve-closed positions.
