Abstract
A flow control valve includes a housing that includes a fluid inlet and a fluid outlet; a valve body that together with the housing, forms a first chamber with a variable volume and a second chamber with a variable volume; a communication passage that connects the first chamber and the second chamber together; and an urging portion that urges the valve body in a direction in which the volume of the first chamber decreases. When the valve body moves in a direction to increase the volume of the first chamber against urging force of the urging portion, the valve body moves closer to the fluid outlet and reduces a degree to which the second chamber is communicated with the fluid outlet.
