Patent ID: 8146564

Claim:
An intake air flow control assembly comprising: a plate adapted to be located between an outlet of an intake manifold and a cylinder head, the plate defining first and second intake passages providing communication between the intake manifold outlet and first and second intake ports of the cylinder head; a first vane rotatably coupled to the plate and located within the first intake passage, the first vane displaceable from an open position where the first vane extends along a first wall defining the first intake passage to a closed position where the first vane extends inwardly from the first wall to obstruct an air flow to the first intake port; a second vane rotatably coupled to the plate and located within the second intake passage, the second vane displaceable from an open position where the second vane extends along a second wall defining the second intake passage to a closed position where the second vane extends inwardly from the second wall to obstruct an air flow to the second intake port; a first pivot member rotatably coupled to the plate adjacent the first wall, the first vane fixed for rotation with the first pivot member; a second pivot member rotatably coupled to the plate adjacent the second wall, the second vane fixed for rotation with the second pivot member; a first arm having a first end fixed for rotation with the first pivot member; a second arm having a first end fixed for rotation with the second pivot member; and a third arm coupled to a second end of the first arm and coupled to a second end of the second arm, the second end of the first arm and the second end of the second arm being fixed for displacement with the third arm.
