A synchronizing valve device is provided to synchronize operation with speeds of two hydraulic cylinders by reducing a flow rate of hydraulic oil supplied to the hydraulic cylinder with the high operation speed. A synchronizing valve device includes a valve body(20), a spool(30), a variable shaft(40), a connection shaft(50), a pusher(60), at least one pushing roller(70), and a compression spring(100). The valve body has an inlet(21) at one end and an outlet(22) at the other end. The spool is installed inside the valve body to adjust cross sections of the inlet and the outlet. The variable shaft is arranged in the same axial direction as the spool to be rotatably installed in the valve body. The connection shaft is arranged on a center shaft inside the variable shaft to be rotatably supported. The pusher slidingly moves on the connection shaft to move the spool. The at least one pushing roller is installed on the variable shaft to be in contact with a tilting groove of the pusher to be rolled. The compression spring elastically pushes the spool toward the pusher. |
