Abstract
PURPOSE: To stabilize action when hydraulic appliances connected to a parallel hydraulic circuit in which directional control valves are coupled in parallel with hydraulic pumps are combinedly operated by hydraulic operating valves, by providing at least one operating signal control valve in a prescribed position.
CONSTITUTION: Pumps 1, 6 are connected to a hydraulic cylinder 4 and a hydraulic motor 5 and the hydraulic cylinder 4 and a hydraulic motor 9 through directional control valves 2, 3 and those 7, 8. The directional control valves 2, 3 and 7, 8 are coupled in parallel with the pumps 1, 6. Pilot pressure caused by an auxiliary pump 16 is appropriately distributed by hydraulic operating valves 10W12 to appropriately regulate the directional control valves 2, 3, 7, 8. Operating signal control valves 13, 14 are provided to control operating signals (c), (d) for the hydraulic operating valve 11. Operating signals (a), (b), (e), (f) are transmitted to the control valves 13, 14 through a shuttle valve 15.
