Patent abstract
A hydraulic steering system has a steering linkage and an actuator actuating the steering linkage. Pressurized hydraulic fluid can be fed to the actuator and removed from the actuator through a return pipe. A device installed into the return pipe counteracts volume flow pulsations by damming up the hydraulic fluid return flow. The device dams up the hydraulic fluid only in the event of an occurrence of a volume flow pulsation.
