Abstract
An improved power steering system for motor vehicles of the type used for steering dirigible wheels is disclosed. In particular, the improved system is a rotary valve equipped power steering system in which the steering wheel is coupled to the rotary control valve via a coupling device having a rotational stiffness characteristic that is less than the rotational stiffness characteristic associated with the rotary valve itself.
