Valve devices for controlling flow of intake air

摘要

A valve device controls a flow of intake air within a surge tank connected to an engine. The surge tank is divided into a plurality of tank chambers by a partition wall disposed within the surge tank. The valve devices include a valve body and a valve member. The valve body has a frame mounted within a communication opening defined within the partition wall. The valve member is rotatably mounted to the valve body in order to open and close a frame opening defined in the frame. A motor is coupled to the valve member in order to rotate the valve member. The motor includes a stator molded integrally with the valve body.
