Abstract
A flow control valve is provided in a manner to be capable of locking a position of a differential screw easily without displacing a position adjusted valve element body. The valve element body is brought into or out of contact with a valve seat provided between a first port and a second port, and is connected to an operation member. The operation member is movably inserted into a cover and urged to a direction toward the valve seat by an urging member. A position of the operation member is adjusted by a differential screw, and accordingly a position of the valve seat is adjusted. A rotation member for exerting a rotation force on the differential screw is slidably mounted in the cover along a moving direction of the operation member without rotating. A locking portion is provided in the rotation member to engage with the cover without rotating when the operation member is slid along its moving direction.
