Abstract

An LUDV-circuit for controlling at least one of a lower-load consumer and a higher-load consumer is disclosed, wherein a metering orifice and a downstream pressure compensator for maintaining constant the pressure drop across the metering orifice constant are associated with each consumer. The pressure compensator of the lower-load consumer is associated with a bypass channel capable of being controlled open, whereby the pressure compensator of this consumer may be bypassed.
