Abstract
A valve of the present invention includes: a valve seat member that has a port, an annular window which communicates with an outlet end of the port, an inner-circumferential valve seat provided on an inner-circumferential side of the annular window, and an outer-circumferential valve seat of the annular window; a first valve body that are stacked on a valve seat member, that can seat on or come off the outer-circumferential valve seat to open or close the annular window, and that has a hole; a second valve body that is contained in the annular window so as to be movable in an axial direction and that closes the hole when abutting on a valve seat member side surface of the first valve body; a second valve body biasing member that is contained in the annular window and that biases the second valve body toward the first valve body; a regulating portion that restricts a movement of the second valve body in a direction in which the second valve body moves away from the first valve body; and a communication passage that secures communication between the hole and the port even when the second valve body abuts on the regulating portion.
