摘要： A combustion type power tool capable of avoiding damage to seal members and a housing to prolong a service life, and capable of enhancing operability and workability. Temperature elevation of a combustion chamber frame due to combustion of a mixture of combustible gas and air is detected by a temperature sensor disposed in a housing. If the detected temperature exceeds a preset temperature, ignition of an ignition plug is prohibited by a prohibiting unit in spite of ON operation of a trigger switch. In this state, alarming is performed by a display to notify the user of the inoperable state of the tool. Similar control can be made when the temperature sensor is disposed at a cylinder, an exhaust cover and the housing.

摘要： A combustion-powered driving tool for driving nails or other fasteners in which the starting characteristics of a motor in the tool are improved by varying the amount of voltage applied to the motor when starting the motor and during normal operations so that the motor is driven to reach the rotational speed required in normal operations quickly. Therefore, the combustion-powered driving tool does not require the use of an expensive low-inertia motor, but can use a relatively inexpensive core-type motor or the like with inferior starting characteristics, while improving the work efficiency and user-friendliness of the combustion-powered driving tool.

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 pneumatically operated screw driver having a moving unit rotatable about its axis by rotation of a rotor and movable axially by a pneumatic pressure. The moving unit includes a spline shaft supported by the rotor through a ball spline, and a drive bit aligned with the spline shaft and engageable with a head of a screw. The spline shaft has an annular flange portion. A movable piston is disposed concentrically over the spline shaft and movable in an axial direction thereof with respect to the spline shaft. A spring is disposed over the spline shaft and is interposed between the movable piston and the flange portion. A stop member is provided to a rotor or a frame body. If pneumatic pressure is applied to the movable piston, the latter is axially moved downwardly and is brought into abutment with the stop member. The spline shaft is also moved axially slightly after the movement of the movable piston. The shrinkage of the spring will generate shape-restoration force thereof to further move the spline shaft after the stop of the movable piston.

摘要： A main valve and a manual operating valve cooperatively control the compressed air supplied to an air motor and a piston. The main valve is responsive to the compressed air supplied from the manual operating valve via an air passage. An orifice is provided in the air passage to reduce the speed of the compressed air supplied to the main valve so that the shift movement of the main valve is delayed when the manual operating valve is closed.

摘要： An air motor has a rotor rotatable in response to the pressure of pressurized air. A cylindrical rotary member is connected to the air motor for causing a rotation in synchronism with the rotation of the rotor. A rotary slider is slidable in the axial direction along the inner cylindrical wall of the rotary member. A rotational force transmitting mechanism is provided for transmitting the rotation of the rotary member to the rotary slider. A shaft has one end fixed to the rotary slider and the other end equipped with a piston and a driver bit holder. The rotational and axial motion of the rotary slider is transmitted to a driver bit held in the driver bit holder. And, a cylinder guides the axial slide movement of the piston responsive to the pressure of pressurized air applied on a pressure-receiving surface of the piston.
