The present invention relates to a hydraulic system for a hydraulically actuable work machine that comprises a switching valve block having a plurality of valve block inputs for a respective connection to a pressure output of one or more hydraulic fluid pumps; having a plurality of valve block outputs for outputting a pressurized hydraulic fluid; and having at least one valve that is arranged between valve block inputs and valve block outputs and that is adapted to selectively produce a fluid connection between a first valve block input and a first valve block output or between the first valve block input and a second valve block output; a plurality of pressure sources, preferably a plurality of separately controllable pressure sources of which each one is connected to a respective valve block input; and a plurality of hydraulic consumers of which each one is connected to a respective valve block output. The system is characterized in that the first valve block output furthermore already has a fixed fluid connection, preferably a fixed exclusive fluid connection, to a second valve block input and in that the steering is connected to the first valve block output.

A travel control valve includes a valve body and a spool. The valve body includes a first pump port connected on an upstream side from a drive control valve, a first connection port connected on a downstream side from the drive control valve, a second pump port connected to a second pump, and a second connection port connected to a second circuit system. The travel control valve can switch a communication opening between the first pump port and the first connection port to a large opening throttle position in which the communication opening remains smaller than that between the second pump port and the second connection port, and a small opening throttle position in which the communication opening remains smaller than that in the large opening throttle position.

A flow distribution control method for a hydraulic system, the hydraulic system comprising N loops L1-LN. The flow distribution control method comprises the following steps: S1: comparing pressures P1-PN at an inlet of an actuator in each loop of the hydraulic system; S2: according to the comparison result, determining a loop Lp1 which requires flow compensation; and S3: conducting flow compensation on the loop Lp1 according to the theoretical flow of the loop Lp1 and an actual flow in the loop Lp1 which flows into the actuator, wherein the number of loops in the loop Lp1 is less than or equal to N. Also disclosed are a flow distribution control device and a flow distribution control apparatus for the hydraulic system, the hydraulic system and a non-transitory computer-readable medium. An electric control pressure pump and a flow supplementing valve are employed to replace a constant pressure difference valve, and the flow of all branches may be supplemented, thereby avoiding the phenomenon of unequal flow distribution being generated due to flow distribution characteristics of a pressure compensation system being affected by the overflow area of the constant pressure difference valve. The foregoing employs a flow compensation scheme, has a simple structure, is insensitive to pollution, and has low investment costs.
