。Selective conduction between the chambers divided into two types by the main shaft and vanes in the liner of a hydraulic torque wrench is carried out through two ports drilled in the liner and the relief valve that slides through the output control valve insertion hole. At the same time, a spool-shaped output control valve (hereinafter referred to as a The transition range of the spool valve (spool valve) is adjusted so that it is proportional to the torque.The opening degree of the two ports is changed to adjust the torque generated during forward rotation, and the maximum torque is always generated during reverse rotation. An output control valve device for a hydraulic torque wrench, which is characterized by:
