Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hydraulic system improved so that piping distances of high pressure pipes may be shortened, piping parts, pipes or the like are reduced in cost, and also troubles such as oil leakage or the like are diminished. SOLUTION: In hydraulic circuits of a civil engineering and construction machine driving an actuator by hydraulic pressure fed from a hydraulic pump, the above actuator and a directional selector valve controlling the actuator are integrally fabricated or the directional selector valve controlling the actuator is arranged in the vicinity of the above actuator, so that distances of oil passages connecting both the actuator and the valve are decreased.
