Valve arrangement for servo-steering of vehicles

摘要

A distributor valve is reset to a neutral position relative to a piston valve in a servo-steering gear by rotational adjustment of a piston rod connected to the piston and extending through a non-rotatable rack externally of the housing enclosing the piston and the distributor valve. The distributor valve is locked in adjusted position at a location externally of the housing relative to one end of the rack to which it is threadedly connected internally of the housing.
