Abstract:
A hydraulic control system for controlling preferably at least two consumers, has a pump with an adjustable delivery quantity supplying pressure fluid, an adjustable metering orifice with which the consumers are each associatable, a power beyond connection to which at least one power beyond consumer is connectable, an inlet pressure governor unit situated downstream of the pump and acted on in a closing direction by a load pressure of the consumers or of the at least one power beyond consumer, the inlet pressure governor unit being provided in a pressure fluid flow path between the pump and at least one of the two consumers, while the power beyond connection branching off from a pressure fluid flow path between the pump and the inlet pressure governor unit, a tank, the inlet pressure governor unit in a spring-prestressed position closing a connection to the at least one of the two consumers and the tank, and in another position a pressure fluid connection to the tank is opened, the inlet pressure governor unit being movable into an additional position in which a throttled connection to the tank is opened.
