| 发明名称 | Recirculation valve and turbocharger | ||
| 摘要 | Provided is a recirculation valve that diverts some of the compressed air in a scroll section to an upstream side of the scroll section via a bypass conduit in an open state and sends the compressed air in the scroll section to a downstream side in a closed state, the recirculation valve including a valve body that is fittable in a branch hole in which the scroll section communicates with the bypass conduit, and an actuator that moves the valve body between the closed state where the valve body is fitted in the branch hole and the open state where the valve body is away from the branch hole, in which the valve body forms an inner surface along an inner wall of the scroll section in the closed state. | ||

| 主权项 | 1. A recirculation valve configured to divert a portion of compressed air in a scroll section to an upstream side of the scroll section via a recirculation conduit in an open state and send the compressed air in the scroll section to a downstream side in a closed state, the recirculation valve comprising: a valve body configured to fit in a branch hole in which the scroll section is configured to communicate with the recirculation conduit; and an actuator configured to support the valve body using a driving shaft and move the valve body between the closed state where the valve body is fitted in the branch hole and the open state where the valve body is spaced apart from the branch hole, wherein the valve body is configured to form an inner surface along an inner wall of the scroll section in the closed state, and the valve body is capable of rotating about the driving shaft in the closed state. | ||
