회전축(5)을 중심으로 윙(2, 3)을 회전시키는 유압 실린더(20)에 급배되는 작동유의 유량을 제어하는 로터리 밸브이며, 회전축(5)을 중심으로 하는 윙(2, 3)의 회전에 수반하여 회전하는 로터(60)와, 로터(60)에 형성되고 유압 실린더(20)에 급배되는 작동유의 유량을 제어하는 제1 제어 유로(61) 및 제2 제어 유로(65)를 구비하고, 제1 제어 유로(61) 및 제2 제어 유로(65)는 로터(60)의 회전에 수반하여, 통과하는 작동유의 흐름에 부여하는 저항이 각각 변화된다.

    A rotary valve that controls a flow rate at which working oil is supplied to and discharged from a hydraulic cylinder (20) that causes a wing (2, 3) to rotate about a rotary shaft (5) includes a rotor (60) that rotates as the wing (2, 3) rotates about the rotary shaft (5), and a first control flow passage (61) and a second control flow passage (65) formed in the rotor (60) to control the flow rate at which the working fluid is supplied to and discharged from the hydraulic cylinder (20), wherein the first control flow passage (61) and the second control flow passage (65) respectively vary a resistance exerted on a flow of the working fluid passing therethrough as the rotor (60) rotates.
