Abstract:
Pressure-cutoff arrangement for an auxiliary power steering system in the end positions of the steering lock, wherein the auxiliary power steering system has at least one working piston (2) which is displaceable in the axial direction in a steering housing (1) and delimits two working spaces (I, II), cutoff valves (7, 17) associated with the said working piston (2), and also stop means (13, 23) which are associated with the steering housing (1) and are displaceable in the axial direction and against which one of the cutoff valves (7, 17) runs, in each case, in the end position and, in doing so, opens for the purpose of cutting off the pressure, characterised in that the stop means (13, 23) are fixed in a force-locking manner, with a retaining force which exceeds an opening force of the cutoff valves (7, 17), by means of a spring (14, 24) acting in the radial direction.
