ABSTRACT:
A steering worm shaft in operational connection with a steering wheel and communicating with an axially slidably arranged steering gear nut, which gear nut affects an additional gear member, for example, by means of a toothing, and simultaneously functions as a servo-piston or is at least fixedly connected to a servo-piston within a housing, which contains a cylinder space; the servo piston dividing a cylinder space into two operational spaces, which are separated from each other, and the steering gear nut at its outer cover is provided with an outwardly extending, axially directed lever in an area remote from the sealing area of the servo-piston; the axial width of the lever corresponding at least with the lift of the servo-piston and engaging an axial-parallel groove in the housing to allow the lever to perform a minute tilting movement relative to the housing when the steering gear nut, due to friction and rise of the worm gear nut during a rotation of the steering worm shaft, is also set into rotation, whereby the tilting movements activate at least one valve member, which is arranged in the housing vertical to the axial direction, serves in such a manner so that the inflow of pressure to, or the outflow of pressure from, the operational spaces is controlled in such a manner so that the movements of the steering gear nut are supported in that axial direction, which are initiated by the steering worm shaft.
