Patent ID: 7870728

Claim:
A hydraulic control arrangement for controlling a number of consumers, particularly of a mobile working machine, which can be supplied with hydraulic fluid by means of a variable-displacement pump downstream of which an input pressure scale is arranged for opening a connection to a tank, wherein an adjustable metering orifice is allocated to each consumer, and comprising a power beyond port to which at least one power beyond consumer can be connected, characterized in that the input pressure scale is adjusted in response to the greatest one of the load pressures of the consumers and the at least one power beyond consumer, wherein the power beyond consumer can be supplied with hydraulic fluid via the input pressure scale and the greatest one of the load pressures is applied to the input pressure scale in the closing direction, wherein in a spring-biased home position the input pressure scale blocks the connection to the power beyond consumer and to the tank and upon adjusting into the opening direction first opens the connection to the power beyond consumer and then to the tank, and wherein a second power beyond consumer is connected which can be supplied with hydraulic fluid via the input pressure scale after the first power beyond consumer.
