    Abstract: The invention relates to a hydraulic system comprising a source of high pressure (A), a consumer (C) connectable to the source of high pressure (A) via a flow control valve (21), and a solenoid valve (22) arranged to control the flow control valve (21). The hydraulic system further comprises a hydraulic pilot valve (31) selectively controllable by the solenoid valve (22) to connect a control chamber (28) in the flow control valve (21) either to the source of high pressure (A) or to a low pressure side (T). When the solenoid valve (22) is actuated, the consumer (C) is pre-pressurized via a by-pass conduit prior to the opening of the flow control valve (21). At the same time, the source of high pressure (A) is arranged to act on a first and a second end (32, 33) of the hydraulic pilot valve (31) wherein a spring (36) is arranged to displace the hydraulic pilot valve (31) and connect the control chamber (28) to the low pressure side (T) to open the flow control valve (21).

    Abstract: The objective of the present invention is to provide a device that accurately communicates a subtle variation of an operation side to an action side. Specifically, in the present invention, an operating device (1) is provided to perform a lock release operation of an extension device (5A,5B). The operating device (1) feeds oil to a valve chamber by pressing a piston. When the flow rate of the fed oil is excessive, the valve is pressed to an opening resisting a biasing force of a compressed spring, thereby a rapid increase in the oil supplied to the action section is suppressed. Further, the supplied oil is suppressed to a very small amount by the throttle section, thereby an increase in the operation amount on the action section side is suppressed while maintaining the supply of the oil.
