Abstract: A hydraulic control system for controlling at least two consumers (2, 4) includes a pump (6) with an adjustable delivery quantity. The consumers are each associated with an adjustable metering orifice (24, 38), having a power beyond connection (72) to which at least one power beyond consumer (74) is connectable. An inlet pressure governor unit (60) is connected downstream of the pump (6) and opens a connection to a tank (T). Its setting occurs as a function of a load pressure of the consumers (2, 4) or of the at least one power beyond consumer (74). The inlet pressure governor (60) is provided in the pressure fluid flow path between the pump (6) and one of the two consumers (2, 4), while the power beyond connection (72) branches off from the pressure fluid path between the pump (6) and the inlet pressure governor (60).

Abstract: A hydraulic control system for controlling preferably at least two consumers, has a pump supplying the consumers with a pressure medium and having an adjustable pump capacity, an adjustable metering orifice assigned to each of the consumers, a power-beyond connection to which at least one power-beyond consumer is attachable, an inlet pressure scale connected downstream of the pump and provided in a pressure medium flow path between the pump and at least one of the two consumers, wherein the power-beyond connection branches off in the pressure medium flow path between the pump and the inlet pressure scale, a spring with a force acting upon the inlet pressure scale in a closing direction, an inlet having a pressure acting upon the inlet pressure scale in an opening direction, wherein the inlet pressure scale is configured so that it is actable upon in the closing direction selectively by either a highest load pressure or by a pressure that is greater than the highest load pressure.

Abstract: The invention relates to a hydraulic control arrangement for actuating at least two consumers (2, 4) which can be supplied with pressure medium by means of a pump (6) with an adjustable delivery rate. Provided in the pressure medium flow path between the pump (6) and at least one of the consumers (2, 4) is an input pressure balance (60), by means of which a connection to a tank can be opened in a controlled manner. A power beyond connection (72) for connecting a power beyond consumer (74) branches off from a pressure medium flow path between the pump (6) and the input pressure balance (60). The adjustment of the input pressure balance takes place as a function of one of the load pressures of the consumer or of a power beyond consumer. Said hydraulic control arrangement permits a prioritized supply to the power beyond consumer and an increase in the regulating pressure difference when supplying power beyond consumers.
