Abstract
A flow control valve comprising a valve seat provided with a valve hole and a seat surface, a valve element formed with a sealing surface corresponding to the seat surface, and a rotary shaft to which the valve element is integrally provided, the central axis of the rotary shaft being arranged eccentrically toward the radial direction of the valve hole from the central axis of the valve hole, and the sealing surface being arranged eccentrically toward the direction in which the central axis of the valve element extends from the central axis of the rotary shaft. The flow control valve has a valve element movement direction restriction member for stopping rotation of the valve element, and thereafter moving the valve element toward the valve seat while also relatively rotating the valve element about the eccentric axis eccentric from the central axis of the rotary shaft, relative to the rotary shaft.
