Abstract
A pressure regulating valve varies an input fluid pressure from a pump to a steering pressure either stepwise or continuously varied in accordance with the vehicle speed and, when a power cylinder control valve alternatively admits the steering pressure into two working chambers of a power cylinder, a reaction chamber control valve alternatively admits the input fluid pressure into only a reaction force chamber of the power cylinder control valve, corresponding to the working chamber fed with the steering pressure, to produce in the reaction force chamber a reaction force increased with increases in the vehicle speed.
