4 Claims. (Cl. 222-3)
The present invention relates to a cigarette lighter
using lique?ed combustible gas as fuel wherein the quan-.
tity of discharge ?ow of the lique?ed gas in a tank from
a burner is adapted to be controlled by moving axially up
and down a hollow movable valve member being formed
at its upper end with the burner thereof.
In the gas lighter referred to above, generally, a hol
low movable valve member is screw threaded in the inner
periphery of a blinded cylindrical sleeve extending with
its bottom portion into the tank, and the upper part of 20
the hollow movable valve member projecting upwardly
beyond the opening of the cylindrical sleeve. An operat
ing ring is attached on the valve member by means of a
spring washer or the like. By turning the operating ring,
