摘要： A pneumatic fastener driving tool includes a main valve operable to cause compressed air to be alternately introduced into and discharged from the upper piston chamber, a first passage leading the compressed air into the main valve chamber, a repeat valve disposed in the first passage for opening and closing the same, and a second passage extending between the lower piston chamber and a repeat valve chamber in which the repeat valve is reciprocably received. With this construction, the repeat valve is reciprocally movable in response to a change of pressure in the lower piston chamber to cause the main valve to reciprocate, thereby reciprocating the piston repeatedly. Since the reciprocating fastener driving movement of the piston is directly related to the reciprocating movement of the repeat valve, the fastener driving work can be achieved reliably without causing any operational failure such as a non-load striking.

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 driver includes a housing in which an accumulator for accumulating compressed air is provided; a trigger provided in the housing; a cylinder stored in the housing; a piston stored to be slidable in the cylinder and driven by the compressed air; and a head valve moving in response to movement of the trigger between an acting position which is distant from the cylinder so that the compressed air acts on the piston and a blocking position which abuts against the cylinder so that the action of the compressed air on the piston is blocked. The cylinder can be arranged at a first position and a second position closer to the head valve than the first position in a state that the head valve moves from the blocking position to the acting position.

摘要： A nail gun having a contact arm normally biased in a direction away from a workpiece by compression springs. A free end of the contact arm is brought into abutment with a workpiece and a trigger is pulled for driving a nail thereinto. In the trigger pulling operation, an inner end of the contact arm is engaged with a trigger arm which is biased by a plunger spring through a plunger. Because the contact arm is held on the workpiece, the plunger is moved to provide ON state against biasing force of the plunger spring. Immediately after the nail driving, a nail gun body is moved in a direction away from the workpiece relative to the contact arm. This causes disengagement of the trigger arm from the inner end, to relatively move the nail gun body toward the workpiece by the biasing force of the compression springs. This means relative movement of the contact arm in the direction away from the workpiece. If the trigger is released, the trigger arm is again brought into engagement with the inner end, because the trigger arm is normally urged toward the inner end by a trigger arm spring.
