Abstract
A flow control valve is disclosed that includes a valve body member having a seating surface that is seated on a valve seated surface. Multiple inflow orifices and multiple outflow orifices may be formed on the valve seated surface or the seating surface, and may be formed so as not to overlap each other in a state in which the seating surface is seated on the valve seated surface. An inside inflow channel that is in communication with the inflow channel and the inflow orifice may be formed inside a member where the inflow orifices are formed and an inside outflow channel that is in communication with the outflow channel and the outflow orifice is formed inside a member where the outflow orifices are formed.
