摘要： A pneumatic power drill comprises a piston (13) reciprocal in a cylinder (12) defined within a cylindrical casing (11) of the tool. A bit (14) is actuable by the piston and means are provided by supplying air and pressure alternatively to opposite sides of the piston to reciprocate the piston in the cylinder. A handle (20) is slidably attached to the casing, resilient connection means being provided between the handle and the casing. The resilient connection means comprise a spring (46) and an air damper formed by compressed air filling a space around spring (46). The resilient connection means ensure that, in use, the vibration transmitted to the handle from the tool is substantially reduced.

摘要： A safety valve comprises a valve member (11) which is movable against spring biasing force (12,13) to close under a predetermined flow rate against valve seats (22, 23) and allow only a small bleed through the valve via slots (28). The housing (10) consists of two parts (14, 15) which are adjustably connected together by screw thread (16), which includes a locking nut (30), enabling the valve to be adjusted and set for operation over a range of different flow rates.

摘要： A tool (10) has a housing (11), a reversible fluid-pressure operated rotary motor (12) which is arranged to drive a bit holder (13) via reduction gear boxes (14 and 15) and a clutch (16) which is designed to slip at a predetermined torque. When a trigger (18) is pressed, pressure air is delivered via a valve (22) to the motor, and in a first position of the valve (22) the motor is driven in a forward direction. When the predetermined torque is reached, the clutch slips and displaces an actuator (69) which opens another valve (40). This in turn creates a pressure differential across the valve (22) which causes it to move to its second position in which pressure air is delivered to the motor to drive it in the reverse direction. When the trigger is released, the valves return to their original positions.
摘要翻译：工具（10）具有壳体（11），可逆流体压力操作的旋转马达（12），其被布置成经由减速齿轮箱（14和15）和离合器（16）驱动钻头夹持器（13）被设计成以预定扭矩滑动。当按下触发器（18）时，压力空气通过阀（22）输送到电动机，并且在阀（22）的第一位置中，马达沿向前的方向被驱动。当达到预定扭矩时，离合器滑动并移动打开另一阀（40）的致动器（69）。这反过来又产生跨越阀（22）的压力差，其使其移动到其第二位置，在该第二位置，压力空气被输送到马达以沿相反的方向驱动。当扳机被释放时，阀门返回原来的位置。
