摘要： An impact torque adjusting device of a hydraulic torque wrench enhances the precision of the magnitude of the impact torque generated, shortens the generation period of impact torques, and enhances the durability when rotating in either of two directions, that is, in normal rotation (when tightening) and in reverse rotation (when loosening). A working fluid path 11b communicates with the inside of a liner 7 serving as a high-pressure chamber H and a low-pressure chamber L when an impact torque is formed. A valve body 11d biased in a direction of releasing the working fluid path 11b is disposed in the working fluid chamber 11b. At the rear back side of the valve body 11d, an oil chamber 15e is formed to communicate with a blade insertion part 8a of a main shaft 8 by way of fluid paths 7c, 7d formed in liner lids 7a, 7b. The working fluid path 11b is thereby narrowed depending on an elevation of the pressure of the working fluid in the blade insertion part 8a of the main shaft 8 elevating along with an elevation of the working fluid in the high-pressure chamber H.
摘要翻译：液压扭矩扳手的冲击扭矩调节装置提高了产生的冲击扭矩的大小的精度，缩短了冲击扭矩的产生周期，并且提高了在两个方向上的旋转时的耐久性，即在正常旋转中（当拧紧）和反向旋转（松开时）。当形成冲击转矩时，工作流体路径11b与用作高压腔室H的衬套7和低压腔室L的内部连通。在工作流体室11b中设置有沿着解除工作流路11b的方向偏压的阀体11d。在阀体11d的后后侧，形成油室15e，通过形成在衬套7a，7b中的流体路径7c，7d与主轴8的刀片插入部8a连通。因此，主轴8的叶片插入部8a中的工作流体的压力随着高压室H内的工作流体的高度而升高，工作流体路径11b变窄。

摘要： A pneumatic tool includes a rotor rotatably received in a housing, a driving shank coupled to the rotor, for being rotated by the rotor and by a pressurized air and having one end for driving a fastener. A pressure releasing device may release the pressurized air after the fastener has been tightly threaded onto the object to be fastened. A fluid container is rotatably received in the housing and coupled to the rotor, for partially receiving the driving shank. The driving shank has one or more paddles for being frictionally driven by the container and by the fluid. A pole is slidably engaged through the rotor, and actuated to release the pressurized air when the fastener has been tightly threaded onto the object.

摘要： An elongated socket tool includes a tubular socket member having a cavity for receiving a hexagonal threaded fastener and a drive member having a recess for receiving the square drive stud projected from a torque wrench. The socket member and the drive member are welded to opposite ends of a tubular metal body which also defines a chamber for receiving a marking fluid. A flow restrictor plate is welded between the body and the socket member and has orifices which control the flow of marking fluid from the chamber into a cylindrical wick confined within the socket member. A removable flexible cap normally covers the socket member when the socket tool is not in use.
