A spindle is rotatably supported crosswise in the intake channel and the throttle body is secured to the spindle for rotation therewith between closed and open positions. The intake channel has a wall with an inside surface of elliptical cross-sectional shape, the throttle body being formed as a planar disk having a circular periphery. The throttle body in the closed position is inclined with respect to the inside surface of the wall and the opposite edges of the valve body are in peripheral contact with the inside surface.
