ABSTRACT:
A fluid power steering system for motor vehicles in which a reaction force is generated to resist manual movement of a control valve piston through which pressurized fluid is supplied to a servomotor. The reaction force is limited by displacement of force limiting valve pistons in response to excessive pressure in reaction chambers. When displaced from its normal position, a force limiting valve sequentially blocks supply of pressurized fluid to one of the reaction chambers and then relieves the pressure in said chamber.
