摘要： A pneumatically operated screw driver having a pneumatically operated rotor rotatably supported in an outer frame. The rotor is only rotatable about its axis. A moving unit is slidably disposed within the rotor. The moving unit has an upper piston and is axially movable upon application of pneumatic pressure to the upper piston. The moving unit is also rotatable about its axis because of spline connection with the rotor. A valve is disposed for selectively applying the pneumatic pressure to the piston and to the rotor. Upon application of the pneumatic pressure, the moving unit is moved downwardly, and the pneumatic pressure is then introduced into the rotor for rotating the same. The rotation of the rotor is transmitted to the moving unit. The valve closes a fluid passage directing to the piston and to the rotor when the moving unit has the lowermost position.

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.

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.

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： 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.
