FLOW CONTROL VALVES

摘要

A flow control valve includes a seal member disposed within an annular space. The annular space is defined between at least one of bearing fitting portions of a flow path defining member and a corresponding valve shaft portion of a valve member opposing to each other in a radial direction with respect to an axis of the valve shaft portion and between an end face of a corresponding bearing and an end face of a valve body portion opposing to each other in a direction of the axis. The seal member can seal between the bearing fitting portion and the corresponding valve shaft portion with respect to the radial direction and can also seal between the corresponding bearing and the valve body portion with respect to the axial direction.
