Abstract
Hydraulic steering arrangement (15) with a steering handwheel (2), which is connected with a manual. pump (3), a pump (18) supplying hydraulic fluid, a steering motor (12) and a steering valve (15) arranged between pump (18) and steering motor (12) and having a valve element (20) steering the flow of hydraulic fluid between the pump (18) and the steering motor (12), the valve element (20) being displaceable by hydraulic pressures originating from the manual pump. In such a steering arrangement it is wanted to create the opportunity of implementing various functions, without having to abandon the ordinary hydraulic control. For this purpose, the valve element (20) has an additional drive (31).
