Abstract
The valve assembly includes a tubular rigid body that can be arranged in the upper wall of a lighter gas reservoir and a hollow rod extending along a central axis from a lower end located within the tubular body to an upper end located outside the tubular body. A retaining member (R), on which the upper end of the tubular body is crimped, surrounds a cylindrical portion of the hollow rod. Movement of the hollow rod through the retaining member from a closed position to an opened position enables gas to flow from a lower hole of the valve assembly to the upper end of the hollow rod. The retaining member (R) made of synthetic resin has an annular shape with a slit that can be circumferentially expanded. This member has a reduced thickness at a contact area with crimped portion of the tubular body.
