ABSTRACT:
A jerk control valve adapted for use in a pilot operated steering system has a pilot operated valve biased to an open position by a spring for communicating left steer and right steer pilot lines to a tank through a pair of orifices. The pilot operated valve is moveable to a closed position blocking communication through the first and second orifices when the highest pressure of the left and right steer pilot lines exceeds a predetermined value. The left and right steer pilot lines are continuously communicated with the tank through a pair of orifice devices.
