  • Patent number: 10907700
    Abstract: According to the present invention, there is disclosed a torque impact mitigator including a hydraulic cylinder having a compression end and a rebound end. A piston rod mounted to the piston and extends out from the hydraulic cylinder through the first end cap. A compression spring is compressed when the piston rod is moved out of the hydraulic cylinder and in a relaxed state when the piston rod is moved towards a second end cap. Bores through the piston allow the passage of hydraulic fluid from the rebound end to the compression end of the cylinder. A relief valve is secured to the piston within the rebound end to momentarily reduce the pressure of the hydraulic fluid caused by an instantaneous hydraulic pressure increase due to the initial movement of the piston from the rebound end to the compression end.

  • Patent number: 10724597
    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 hydraulic cylinder. A rod clevis is secured to the second end of the piston rod. 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. A damper tube connecting the compression end and the rebound end of the hydraulic cylinder to direct the hydraulic fluid therethrough to further control the speed of the piston.

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.
