Abstract
PURPOSE: To restrain unnecessary power consumption by a method wherein the difference of fluid pressure between a supply circuit in a pressure fluid circuit in which a plurality of directional control valves are arranged in series and another supply circuit connected with actuators by the operation of directional control valves is controlled at a definite value.
CONSTITUTION: The 1st fluid circuit 1 consists of directional control valves 3a, 3b connecting with actuators 8a, 8b, a flow dividing valve 5 and a high pressure selecting circuit 11. On the other hand, the 2nd fluid circuit 2 consists of directional control valves 4a, 4b connecting with actuators 9a, 9b, a pressure compensating valve 6 and a high pressure selecting circuit 12. The directional control valves 3a, 3b and 4a, 4b of each fluid circuit 1, 2 are composed of the load circuits 30aW 30d and 31aW31d, the 1st supply circuits 16, 18 for transmitting one of two fluid pressure signals through a flow dividing valve 5 and a pressure compensating valve 6, the 2nd supply circuits 37aW37d for transmitting the other of said fluid pressure signal and pilot sequence valves 42aW42d.
