Abstract:
Provided is a rotary valve for controlling the flow rate of hydraulic oil supplied to and discharged from a hydraulic cylinder (20) for rotating a wing (2, 3) about a rotating shaft (5). The rotary valve is provided with: a rotor (60) which rotates as the wing (2, 3) rotates about the rotating shaft (5); and a first control conduit (61) and a second control conduit (65), which are formed in the rotor (60) and which control the flow rate of hydraulic oil supplied to and discharged from the hydraulic cylinder (20). The resistance of the first control conduit (61) and the second control conduit (65) to the flow of hydraulic oil passing through the first control conduit (61) and the second control conduit (65) changes as the rotor (60) rotates.
