Abstract:
A hydraulic circuit for controlling at least one of a lower-load consumer and a higher-load consumer (4, 6), including a variable displacement pump (2) the setting of which is variable as a function of the load pressure of the Consumers (4, 6), with an adjustable metering orifice (14a, 14b) comprising a downstream pressure compensator (16a, 16b) being provided between said variable displacement pump (2) and each consumer (4, 6), the control piston (72) of which may be acted on in a closing direction by the load pressure of the associated consumer (4, 6) and in an opening direction by the pressure downstream from said metering orifice (14a, 14b), characterized by a bypass channel (32) connecting the metering orifice output (P1) with at least one work port (A) for the lower-load consumer (6) while bypassing said associated individual-pressure compensator (16a).
