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 nail driver uses a motor for driving a fan. A motor holder formed from plastic accommodates the motor. A cylinder head has a motor holder receiving portion in which the motor holder is slidably movably disposed. A coil spring has one end secured to the motor holder and another end secured to the cylinder head to thereby support the motor holder. Initial acceleration applied to the motor when combustion occurs can be suppressed and impact imparted upon the motor can also be suppressed by friction between the outer periphery of the motor holder and the inner periphery of the motor holder receiving portion. A heat shielding plate is interposed between the lower end surface of the motor and the cylinder head in order to prevent hot air combustion gas from entering into the motor.

摘要： A combustion type power tool capable of restraining reduction in output power due to lowering of combustion efficiency. A specific space within a combustion-chamber frame is enlarged. The specific space contains a specific region where high turbulence occurs in a combustion chamber at which a fuel is ignited. The enlargement is made by providing an enlarged distance between a rotation shaft of the fan and an inner wall of the combustion-chamber frame. When the turbulent combustion occurring at the specific region is expanded in the combustion chamber, flame propagation contour of the turbulent combustion reaches the wall of the combustion-chamber frame and ribs at a delayed timing. Therefore, after the turbulent combustion is sufficiently promoted, the flame reaches the combustion-chamber frame and the ribs. In other words, the flame does not reach the combustion-chamber frame and the ribs at the initial stage of turbulent combustion.

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.
