Abstract
A torque impact mitigator including a housing assembly having a hydraulic cylinder. A piston is disposed within the hydraulic cylinder. A piston rod is mounted at a first end to the piston and having a second end extending out from the compression end. A compression spring is disposed between the piston and an end of the cylinder. A rod clevis is secured to the second end of the piston rod to compress the compression spring into a compressed state when the rod clevis is moved away from the cylinder and to release the compression spring into a relaxed state when the rod clevis is moved towards the cylinder. A plug is disposed within an upper end of the compression spring and having a bore extending therethrough to receive the piston rod. One or more bores are disposed through the piston to allow passage of hydraulic fluid into the hydraulic cylinder.
