Claims

[Scope of Claim for Utility Model Registration] An opening/closing valve body sliding guide hole 2 is bored from above, and a starting fuel nozzle 4 connected to the starting fuel chamber 3 is opened at the bottom 2A of the opening/closing valve body sliding guide hole 2, and the opening/closing valve body is opened/closed. A starter main body 1 has a starting air passage 6 and a starting air mixture passage 7 opened in the side wall 2B of the valve body sliding guide hole 2, and an inner cylinder 1 in the upper opening 2E of the opening/closing valve body sliding guide hole 2.
A cylindrical housing 10 is provided with the lower openings 10C of the housing 10 being connected and the upper opening 10D of the inner cylinder 10A being open and standing upright from the starter body 1; A casing 11 that closes the upper opening 10D of the casing 10 and has a terminal 16A on one side connected to the lead wire 15A on one side and a terminal 16B on the other side connected to the lead wire 15B on the other side, A thermally responsive body 1 in which a thermally expandable material is sealed and converts a change in volume of the thermally expandable material due to a temperature change into the stroke of a control rod 12A protruding from one end.
2, is movably arranged in the opening/closing valve body sliding guide hole 2 and operates synchronously with the control rod 12A of the heat-sensitive responsive body 12, and is connected to the starting air passage 6 and the starting air mixture passage 7.
