ABSTRACT:
A power steering gear has a variable restriction structure disposed along an oil passage between a control valve housed in a steering gear box and a power cylinder engaging a steering rack. The variable restriction increases the flow cross-section through the restricted oil passage between the control valve and the power cylinder as the hydraulic pressure in the control valve increases so as to reduce the required steering force when relatively hard steering is called for.
