Abstract

PURPOSE: To reduce pressure loss and improve responsiveness by making a selector valve operate by the pressure of a circuit when an upperstream-side selector valve is selected and by forming a parallel circuit just behind the selector valve into a tandem circuit.
CONSTITUTION: When a plunger 5 is moved to either right or left position, the selector valve 7 is operated by signal pressure of signal chambers 22 and 23 caused by the movement and thereby supply passages 13 and 14 are selected into the tandem circuit, while a plunger 6 is operated simultaneously. By this constitution, no excessive oil flows to the plunger 6 even when the load of an arm cylinder is light, whereby the independence of a swiveling motor connected to the plunger 5 is retained accurately. And, when the swiveling motor is not employed, the passages are turned to be the parallel circuits, whereby the same operational feeling with usual operability can be obtained.
