摘要： A combustion-type power tool having a cooling arrangement for cooling a cylinder. The tool includes a housing, a cylinder head at one end of the housing, a push lever disposed at another end of the housing, and a combustion chamber frame including a base section and a head section. The head section has a disc like connecting portion extending from an end of the base section and a sleeve like abutment section extending from the connecting portion toward a cylinder head. A fan is disposed in a combustion chamber and is fixed to a rotation shaft of a motor supported to the cylinder head. The fan has fan blades. The fan blades define a widthwise center line in the axial direction of the rotation shaft. The center line is offset from the connecting portion and toward the push lever. The fan blades define widthwise edges in confrontation with the cylinder head. The widthwise edge is positioned in alignment with the connecting portion or offset therefrom toward the cylinder head.

摘要： A combustion-type power tool having a cooling arrangement for cooling a gas canister. The tool includes a housing having a gas canister accommodating section in which a gas canister is accommodated. An air passage is defined between the gas canister accommodating section and the gas canister accommodated therein. The gas canister accommodating section is formed with an air inlet port in communication with the air passage for introducing air into the air passage. Since air flows along the gas canister, the gas canister can be cooled. If the tool is provided with a fan, the rotation of the fan causes air suction passing through the air passage.

摘要： A combustion-type power tool includes a cylinder having a peripheral wall which has an inner peripheral surface and an outer peripheral surface. The peripheral wall is formed with an exhaust hole at a first axial position. A piston is reciprocally movable in an axial direction and is slidable in contact with the inner peripheral surface. A combustion-chamber frame is abuttable on a head portion to provide a combustion chamber in cooperation with the head portion and the piston. The piston allows the combustion chamber to be in fluid communication with an atmosphere through an upper space above the piston and through the exhaust hole when the piston is located at a bottom dead center. The fin is disposed at the outer peripheral surface and has a portion extending in a direction slanted in relation to the axial direction and oriented toward the exhaust hole.

摘要： A combustion type power tool having a fan capable of providing a desirable turbulence in a combustion chamber. A fan is rotatably disposed in a combustion chamber and driven by a motor. The fan has fan blades each having a leading edge and a trailing edge. An angle of the leading edge relative to a rotational plane of the fan is approximately equal to an angle of the trailing edge relative to the rotational plane, whereby high degree of turbulence is generated from the position near the leading edge.

摘要： An oil pulse tool includes a motor, an oil pulse unit, an output shaft on which a front end tool is attached, a torque detecting sensor for detecting generation of an impact torque, and an operating portion configured to detect a time period between a first impact torque detected by the torque detecting sensor and a second impact torque detected by the torque detecting sensor. The second impact torque is smaller than the first impact torque. The operating portion carries out a notification when the time period between the first impact torque and the second impact torque is less than a predetermined evaluation value for the time period between the first impact torque and the second impact torque.

摘要： A dust collection cover capable of efficiently collecting cutting chips and residues generated as a result of cutting a workpiece. A cutter includes a motor and a rotary blade driven by the motor, and the dust collection cover is attached to the cover for covering a part of the blade. The cover is formed with a dust discharge port through which cutting chips and residues are discharged. The cover has a guide arrangement for directing the cutting chips and residues toward an interior of the cover body. The arrangement provides a blowing-out air blowing to the workpiece, or a rod-like member removing the cutting chips and residues.
