Abstract
A steering valve arrangement of a hydraulic steering system has a rotary valve with a first and a second control part that are rotationally movable relative to one another. By rotational adjustment of the control parts a hydraulic servomotor is controlled which is connected drivewise with the steered wheels of a vehicle. An electric motor is mounted in a fixed location for actuating the rotary valve relative to the first control part and is connected drivewise with the second control part. The driving connection from the electric motor to the second control part is provided indirectly by a step-down transmission, including a small gear fixed to the motor drive shaft and a large gear connection with the second control part. The steering valve and the motor are disposed side by side and parallel to one another in a compact design.
