A hydraulic steering apparatus with steering amount amplification is provided, wherein a metering device for supplying pressure medium to steering cylinders is actuated in accordance with an amount of rotation of the steering wheel. With the aid of a control block it is possible to deliver an additional pressure medium volume to the steering cylinders, wherein control of the control block is effected through the intermediary of a control circuit containing an effective control pressure that is substantially lower than the load pressure for transmitting the steering moment at the steering cylinder. A spring assembly for the control block is also provided, wherein two springs are arranged in parallel, one of which only takes effect following a predetermined stroke of the control element.
