Abstract

PURPOSE: To smoothly control the quantity of outflow, by keeping the cross-sectional area of a port small at the initial stage of retraction of a hydraulic cylinder and gradually opening the port to a prescribed degree.
CONSTITUTION: When the hydraulic cylinder 6 is retracted, a control switch 30 is connected to a contact 34 to energize a solenoid 12 to shift a valve 13. At that time, a fluid flows out of the hydraulic cylinder 6 through an oil drain pipe 15 into a chamber 20 of a valve cylinder 23 wherein a balance piston 26 is fitted. As a result, the valve cylinder 23 is moved back despite the force of a second spring 28 and the port 22 is gradually opened. The elastic force of the second spring 28 is stronger than that of a first spring 27. The fluid flows out of the hydraulic cylinder 6 through the port 22 whose cross-sectional area is set small at the initial stage of retraction of the cylinder. The cross-sectional area of the port 22 is thereafter gradually increased. Thus, the cylinder is smoothly moved.
