Abstract

A power steering mechanism for controlling the dirigible wheels of an automotive vehicle comprising a fluid motor that provides a power assist to manual steering effort applied to the steering gear mechanism wherein a hydraulic reaction mechanism (44) applies a reaction torque to the driver operated steering controls (82) to effect variable steering effort thus making it possible to reduce the steering effort at low vehicle speeds (e.g., while parking the vehicle) and increasing the steering effort as the vehicle speed increases, the variable effort being accomplished by reaction pistons (96, 98, 100, 102) that are subjected to steering pressure.
