Fluid control valve

A fluid control valve, comprising:

• a valve housing provided with an inlet port and an outlet port;
• a valve body configured to be driven by a drive source;
• and
• a spring configured to urge the valve body in a direction opposite a direction of driving by the drive source,
• wherein a valve seat is formed at an edge of a through-flow passage, the valve body and the valve seat forming a poppet valve that controls a flow rate in accordance with a movement of the valve body,
• a flow passage on a downstream side of the poppet valve is provided with a reduction region where a flow passage cross-sectional area tends to decrease toward the downstream side,
• wherein the valve seat is formed by an annular tilted surface which is tilted with respect to an axial direction and which is formed inside the valve housing,
• an inner peripheral surface which is connected continuously and directly to a downstream side edge portion of the annular tilted surface forming the valve seat is formed inside of the valve housing, and
• the inner peripheral surface is a parallel peripheral surface which is parallel to the axial direction or a tilted peripheral surface which is tilted toward the valve body from an upstream side to the downstream side.
