| description | A hydraulic control arrangement (1) is described having a directional valve (2), a metering pump unit which has at least two metering pumps (3, 4) which are connected hydraulically in parallel and are operable mechanically in parallel, and a shut-off valve (6) in hydraulic connection between two of the at least two metering pumps (3, 4), a pump connection (P) and a tank connection (T) which are connected to said metering pump unit by way of the directional valve (2), and two working connections (L, R) connected to the directional valve (2), a control input (8) of the shut-off valve (6) being connected to the pump connection (P) by means of a control valve. Such a control arrangement should be operated at a high hydraulic pressure and at the same time it should be made sure that the shut-off valve is actuated only when the required high pressure is available. To this end the control valve (10) is a pilot operated valve, an inlet (11) of said control valve (10) being connected to the pump connection (P), said control valve (10) connecting said input (8) and said pump connection (P) in an actuated state of said control valve (10). |
