A hydraulic unit for supplying pressure to a hydraulic steering system is provided having at least two hydraulic cylinders and at least one hydraulic pump (9, 10, 32, 33). It is essential that the hydraulic cylinders are of interacting configuration, by an annular space (6a, 6a, 28a, 28b) of the first hydraulic cylinder being connected via at least one hydraulic line to an annular space (6a, 6a, 28a, 28b) of the second hydraulic cylinder, and a piston space (5a, 5b, 29a, 29b) of the first hydraulic cylinder being connected via at least one hydraulic line to a piston space (5a, 5b, 29a, 29b) of the second hydraulic cylinder, and a hydraulic pump (9, 10, 32, 33) being arranged at least in a hydraulic line (7, 8, 30, 31) between the two annular spaces (6a, 6a, 28a, 28b) or in a hydraulic line (7, 8, 30, 31) between the two piston spaces (5a, 5b, 29a, 29b). Furthermore, the invention relates to methods for operating a hydraulic unit for supplying pressure to a hydraulic steering system, and to a steering system.
