Abstract
In a damper valve for use in a steering damper arrangement of a motor vehicle having a hydrostatic displacement motor for operating the vehicle steering mechanism wherein hydraulic fluid lines extending between the hydraulic motor and a servo-valve include the damper valve, the damper valve has a throttling arrangement which permits fluid flow in one direction and limits fluid flow in the opposite direction but permits essentially unlimited fluid flow in both directions as long as the pressure difference across the damper valve is below a predetermined threshold value so as to permit unrestricted normal steering movements of the vehicle steering system, but dampen shock movements thereof.
