Abstract
A valve for a gas lighter wherein an elongated support body of low thermal conductivity is clamped in a tubular member forming a valve seat at its upper end to lock a flame-height-controlling filter in place below this valve seat. The improvement resides in the formation of the thermally conductive burner-carrying member with a tubular apron, skirt or sleeve which is fitted over the thermally conductive valve member and slidingly guided therein to press a valve body (rubber gasket or flap valve) against the valve seat. The gas passage in the burner member is formed only in the upper end thereof, while the apron extends into the well beyond the filter.
