摘要： In the combustion-type power tool, a first shelter wall and a second shelter wall are disposed to partially surround an area between an ignition plug and an ignition ground. Two gaps are provided between the first and second shelter walls. The first shelter wall extends radially outwardly from an outer peripheral surface of a motor boss, and also protrudes from an end face in an axial direction of a fan shaft. The first shelter wall has a lower end surface inclined such that an axial length between the end face and the lower end surface is gradually reduced toward radially outer end of the first shelter wall.

摘要： A combustion-type power tool includes a cylinder and a combustion chamber disposed on top of the cylinder that accommodates a gaseous mixture of existing air in the combustion chamber and fuel injected therein. A spark plug generates a spark to combust the gaseous mixture in the combustion chamber. A trigger switch produces the spark in the spark plug when operated. A piston is movably supported in the cylinder and driven by combustion in the combustion chamber. A driving blade is integrally formed with the piston for driving a fastener. A push lever is provided at one end of the housing and coupled with the combustion chamber frame. A temperature sensor is provided, for example, on the combustion chamber frame to sense the temperature thereof. A stopper is operated to adjust the position of the push lever to be shifted from an initial position when the sensed temperature is higher than a critical value. The push lever is positioned farther from another end of the housing when adjusted than when the push lever is in the initial position.

摘要： A combustion-type power tool capable of preventing a sub-stream of air-fuel mixture from passing through a gap between an electrode and an opposing electrode section, and yet capable of providing a desirable ignition without lowering maintenance efficiency of the tool. The opposing electrode section opposes the electrode of an ignition plug body. A head cap supports the opposing electrode section at a position closer to an axis of a fan than the electrode to the axis. The opposing electrode section protrudes from the head cap outward in the radial direction of the fan. The side of the head cap defining a combustion chamber has three parts. A first part surrounds the rotation axis of the fan. A second part supports the ignition plug body. A third part located in the radially outer side of the second section with respect to the axis.

摘要： A combustion type power tool capable of performing cleaning to a cleaning target from outside of the tool without disassembly of a head cover and a head cap. In the head cap, first and second cleaning passages are formed. The first cleaning passage has one end open to an atmosphere and a closed inner end. The second cleaning passage has one end in communication with the first cleaning passage and another end open to a spark generating portion which is one of the cleaning target in the combustion type power tool. A check valve is disposed in the first cleaning passage for normally closing the one end of the first cleaning passage by a biasing force of a compression coil spring. If a nozzle of a compression type cleaning liquid canister is inserted into the one end of the first cleaning passage and the cleaning liquid is injected, the check valve is opened by the injection pressure, so that cleaning liquid is supplied to the cleaning target through the second cleaning passage.

摘要： A combustion-powered nail gun drives nails into a workpiece when both a head switch and a trigger switch are turned ON while a safety switch is turned ON. The nail driving operation cannot be performed if the safety switch is not ON even if both the head switch and the trigger switch are ON. The head switch is turned ON when a push lever is urged against the workpiece. Fuel/air mixture in a combustion chamber is ignited when the head switch and the trigger switch are turned ON irrespective of an order in which the head switch and the trigger switch are turned ON, whereby “successive-shot driving” can be performed in which the trigger switch is maintained in its ON position while successively driving a plurality of nails at different locations of the workpiece by repeatedly pushing and releasing the push lever toward and away from the workpiece.
