ABSTRACT:
Centrally mounted in a strain decoupling fashion on a hydraulic torque wrench is a hose connect swivel. A base ring of the swivel features a first fluid transmitting joint that is fluid transmitting connected with axial studs extending from the base ring into mating holes in the torque wrench housing. The base ring is radially spaced apart and surrounding a central housing portion of the torque wrench. The radial spacing provides for a strain and deformation decoupling of the base ring from the torque wrench housing such that leakage in the fluid first transmitting joint is prevented. A second fluid transmitting joint provides together with the perpendicular first fluid transmitting joint for a three dimensional orienting of the hose connect terminal around the torque wrench housing while providing access to the piston side peripheral end of the torque wrench housing for an eventual reaction arm.
