Abstract

The steering system of a motor vehicle includes a two chamber steering motor having the application of pressurized fluid applied thereto through change over valves in one position by the way of a by pass valve and alternately in a second position by the way of a steering unit. The change over valves are operated from their first position to their second position upon activation of the steering unit which results in control valve moving from a position applying pressurized fluid from a pump to the by pass valve to a position applying pressurized fluid from the pump to the steering unit.
