摘要
A compact hydraulic torque wrench which has an efficient design enabling it to be relatively small in size. The arrangement of the return spring for the hydraulic cylinder provides increased strength and reduces the size of the unit. The device is constructed to enable the drive arm to go through the entire travel without change in alignment. Additionally, the device includes a braking system for the reaction arm to ensure that a ratcheting effect occurs and that the proper return of the hydraulic piston can be accomplished by means of a return spring without the necessity for a hydraulic return of the piston.
