Zusammenfassung:The invention relates to a steering device for vehicles with a double-acting hydraulic working cylinder, which is divided into two working chambers by a piston, which is displaceably mounted in the working cylinder, to pivot at least one vehicle wheel, and a pressurizing means device producing a volume flow of a hydraulic medium, the hydraulic medium being supplied to a rotary slide valve, which supplies the volume flow, depending on the rotary slide valve position, to the working chambers of the double-acting hydraulic working cylinder or to a reservoir for the hydraulic medium, wherein when a certain pressure is exceeded in the feed line to the rotary slide valve, a pressure relief valve guides at least a part of the total volume flow of the hydraulic medium past the rotary slide valve in particular to the reservoir.
