Claim:
1. A hydraulic control assembly for at least two consumers, comprising: a hydraulic pump; a respective supply metering orifice for each of the consumers, wherein each supply metering orifice is configured to control a consumer fluid flow for a corresponding consumer and has an inlet side connected to the hydraulic pump; a plurality of detection orifices positioned hydraulically in series with one another in a flow-sensing fluid flow path, wherein each supply metering orifice is assigned a respective detection orifice of the plurality of detection orifices; and a control device configured to control a pump fluid flow from the hydraulic pump to the supply metering orifices, wherein: the flow-sensing fluid flow path extends from the hydraulic pump, through the plurality of detection orifices in series, and to the control device, and fluid from the flow-sensing fluid flow path influences the control device for controlling the pump fluid flow, when a pressure differential over one of the supply metering orifices falls below a threshold, the respective detection orifice closes the flow-sensing fluid flow path, and when a pressure differential over one of the supply metering orifices exceeds the threshold, the respective detection orifice opens the flow-sensing fluid flow path.
