Abstract
A push-fit inlet valve assembly for the opening into the fuel chamber, such as in a lighter, consists of a flexible valve member and a rigid stem fitted into a bore in the valve member. The valve member, tightly secured in the fill opening, normally effects the closure of the opening preventing any escape of the pressurized fuel. To add fuel, the stem is pressed inwardly and displaces the valve member from sealing contact with the opening and affords communication between the interior of the chamber and the ambient atmosphere. Such communication between the chamber and the atmosphere is provided by a groove formed in the outer surface of the valve member which is opened to the chamber when the stem presses the valve member inwardly.
