ABSTRACT:
The invention relates to a reaction or open center type hydraulic steering control system which is adapted for use with a bidirection differential type servomotor having a piston rod extending from only one side thereof. A loaded check valve in a selected one of the lines to the servomotor compensates for relatively low above atomospheric pressures sometimes present in the line leading from the open center passage of the control unit to the exhaust tank when the control unit is in a neutral position.
