    摘要： There is provided a fastener driving tool having a control valve arrangement including a trigger valve, a cycling valve and a safety valve. The cycling valve is adapted to repetitively cycle the driving piston of the fastener driving tool through power and return strokes or to provide for single-cycling of the piston through a drive and return stroke in response to the position of the trigger. In addition there is provided an arrangement wherein the operation of the piston is arrested when the bumper cushioning the power stroke of the piston is excessively worn.

    摘要： A pneumatic fastener driving tool includes a safety arrangement that requires the tool to be placed against a workpiece before a manual trigger valve is operated in order to permit the tool to fire. Once the tool is placed against the workpiece the safety arrangement prevents ''''touch'''' firing by moving the tool toward and away from the workpiece. In one embodiment, the safety arrangement includes a fluid controlled piston which is operated to mechanically latch a workpiece actuated safety in its normal position to prevent tool operation whenever the trigger is operated before the tool is placed against a workpiece and whenever an attempt is made to ''''touch'''' fire the tool with the trigger held operated. In a second embodiment, a fluid controlled piston mechanically latches the trigger valve in normal position until after the workpiece actuated safety has been operated.

    摘要翻译： 气动紧固件驱动工具包括安全装置，其需要在手动触发阀操作之前将工具放置在工件上，以允许工具起火。 一旦工具放置在工件上，安全装置通过将工具移向和远离工件来防止“触摸”触发。 在一个实施例中，安全装置包括流体控制的活塞，其被操作以将工件致动的安全性机械地闩锁在其正常位置，以防止在将工具放置在工件之前操作触发器时的工具操作，并且每当尝试 “触摸”触发手柄触发工具。 在第二实施例中，流体控制的活塞将触发阀机械地锁定在正常位置，直到工件致动的安全性已被操作。
