(57) A pocket lighter is disclosed which comprises a measuring chamber (21, 125) an inlet
valve (19, 20, 117, 120) and an outlet valve (17, 23, 119, 124), the inlet and outlet
valves (19, 20, 117, 120, 17, 23, 119, 124) being arranged such that opening of the
outlet valve (17, 23, 119, 124) permits fuel to flow from the measuring chamber (21,
125) resulting in the inlet valve (19, 20, 117, 120) being closed, and closing of
the outlet valve (17, 23, 119, 124) results in the inlet valve (19, 20, 117, 120)
being opened to permit fuel to flow into the measuring chamber (21, 125).
