When the Trigger
[98]
is released, the
Chamber Lock Bar
[100]
is returned from the
position under the Chamber
[24]
to the original
position. Thus the Chamber
[24]
and the
Pushing Lever
[64]
are placed in the initial
state and sealing by the O-rings
[15]
and
[36]
is released. When the Fan
[20]
rotates, air
passes through the Filter
[4]
, enters the
combustion chamber and goes to the outside
in order to discharge gas and cool the
combustion chamber (Fig. 8).
