Combustion power tool

It is an object of the present invention to provide a combustion power tool (101) having a rational combustion. A representative combustion power tool (101) according to the invention may include a combustion chamber (121,122), a fuel supplier (141) to supply fuel into the combustion chamber (121,122), an igniter disposed in the combustion chamber (121,122), a driving mechanism (151) actuated to perform a predetermined operation by utilizing a combustion pressure generated when the fuel is burned in the combustion chamber (121,122) and an actuator (107) that operates the fuel supplier (141) and the igniter (131) in one operation. Based on the operation of the actuator (107), fuel is supplied into the combustion chamber (121,122) via the fuel supplier (141) and the igniter (131) performs ignition in relation to the pressure of the fuel supplied into the combustion chamber (121,122). According to the invention, because the fuel supply and ignition can be done by the actuator (107) in one operation, ignition can be performed in constant timing after fuel is supplied via the fuel supplying means. As a result, the operability can be improved and stable combustion can be always achieved.
