  • Patent number: 11920685
    Abstract: A valve device includes a rotation shaft, a valve body, and a biasing portion. The valve body is configured to be rotationally displaceable about the rotation shaft between a closed position and an open position. The biasing portion biases the valve body so as to cause the valve body to approach the closed position. The valve body includes an upstream wall arranged in a position upstream of the rotation shaft in a flow direction of the fluid when the valve body is in the closed position. The valve body includes a rotation end, which is an end distal from the rotation shaft and moves downstream in the flow direction of the fluid in response to a displacement of the valve body from the closed position to the open position, and the rotation end is shaped to project upstream when the valve body is in the closed position.
