前記減圧弁。[Scope of claim for utility model registration] A composite control valve with an attachment valve consisting of the following configuration. An inlet chamber connected to a hydraulic power source such as a pump, and a spool for selectively supplying pressurized oil in the same chamber to the actuator and passing return oil from the actuator to the tank (the position of which can be switched); an attachment valve having a return passage connected to the tank; (B) an inlet chamber connected to the hydraulic power source via the attachment valve; and a plurality of spools connected to the same population chamber in a neutral state; A composite control valve having a bypass passage connected to the tank from a return passage that passes through the center of the spool and is downstream thereof. (C1 A hollow valve provided between the bypass passage and the return passage of the composite control valve. A loading valve having a body, a spool slidably inserted into the valve body, and a pilot chamber configured by one side of the spool and the cylinder. a cylinder, a valve member fixed to the spool end of the attachment valve to slide within the cylinder, and a chamber provided approximately in the center of the cylinder and connected to the pilot chamber of the loading valve via a pressure reducing valve. and a passage provided on both sides of the chamber of the cylinder and connected to the return passage of the attachment valve. The pressure reducing valve connected to the chamber of the switching valve.
