PROBLEM TO BE SOLVED: To provide a hydraulic control unit with enhanced efficiency and a valve block to be used for the control unit.SOLUTION: A hydraulic control unit is provided with an adjustable hydro pump 2, in which a pressure medium can be supplied to at least one hydraulic consumption device 6 through a pumping passage 4 of the hydro pump 2. The hydraulic control unit is also provided with a pump regulator 32 and a work volume flow rate of an adjusting device 36 of the hydro pump 2 can be adjusted relating to the pumping pressure and the highest load pressure of one or more hydraulic consumption devices 6 via the pump regulator 32. The hydraulic control unit is further provided with a pressure reducing device 56 for the highest load pressure. The pressure reducing device 56 is adjustable relating to the work volume flow rate. |
