Abstract

Improvements introduced in the distribution valves to control the pressure medium in power steering; especially for motor vehicles, consisting of a valve cylinder, a piston displaceable axially with respect to the valve cylinder and two reaction pistons not displaceable with respect to the valve cylinder and guided in axial bores of the characteristic valve piston. because in a axial bores of each reaction piston oriented towards the center of the valve piston, a damping piston is arranged movably, whose outer and internal damping spaces formed with the reaction piston on one side and with the reaction piston and the valve piston on the other hand communicate through throttle bores, which open into the outer and inner annular spaces of smaller radial dimension formed by the reaction piston and the valve piston, with an intake space or respect . with an annular groove in the valve plunger.
