  • Vibration jacks
    Patent number: 4463838
    Abstract: An improved vibration jack is presented wherein the excess energy which might develop from overpressurizations and cause loss of control, is absorbed. This excess energy is transmitted to fluid within a chamber by means of an extension of the jack piston rod. Maintaining the fluid in the chamber at a constant pressure, and allowing discharge of fluid when this pressure is exceeded allows the fluid to absorb any excess energy.
