Vehicle intake manifolds

摘要

Air intake manifolds (32) for vehicle engines (50) may include a plate-shaped short runner valve (16) that is rotatably disposed within an aperture (19) of a wall partition (42). The valve (16) may be operated to open and close the aperture. A flange (22) may extend from an inner surface of the aperture and the flange may define a sealing face (22b). An elastic sealing member (21) may be disposed along a peripheral edge of the valve. The sealing member may include first and second projections (21a, 21b) extending from the peripheral edge of the valve. The first and second projections may be arranged in a substantially V-shape. Further, the terminal ends of the first and second projections are preferably disposed so as to closely contact the sealing face when the valve is rotated to the closed position.
