ダの制御装置。 A cylinder port and a pilot port are formed in the spool valve, and this cylinder port is connected to the cylinder. Depending on the switching direction of the spool built into this spool valve, the cylinder port is communicated with the supply passage or the return passage, and the cylinder port is connected to the cylinder port. In an operating check device configured to allow free flow from the cylinder to the cylinder, an operating check valve that allows flow only to the cylinder is provided at the cylinder port, and a pilot of the operating check valve is installed in the poppet of the operating check valve. The pilot chamber is formed with an orifice that communicates with the pilot passage, and a regulator valve that detects the fluid pressure difference between the cylinder port and the return passage and controls the opening of the operating check valve is incorporated. A cylinder control device configured as follows.
