Abstract
PURPOSE: To enable the fine adjustment of control of a hydraulic mechanism and improve its operating property, by providing direction control solenoid valves which correspond to hydraulic appliances such as cylinders and by connecting the solenoid valves to a pump and a tank through a manual direction control valve.
CONSTITUTION: As for an oil pressure controller for operating three cylinders 2aW2c, spring-returned solenoid valves 3aW3c, each of which has four ports and two positions, are provided correspondingly to the cylinders 2aW2c. The solenoids 4aW4c of the valves 3aW3c are connected in parallel with a power source 6 through switches 5aW5c. The solenoid valves 3aW3c are coupled in parallel with a pump P and a tank T through a manual direction control valve 1. The switches 5aW5c can be turned on or off in prescribed combination, by operating the manual changeover lever 7 of the control valve 1, to change over the solenoid valves 3aW3c to drive the desired cylinders 2aW2c.
