Abstract
A throttle body for traction control includes a secondary throttle shaft, a secondary throttle valve rotatable with the secondary throttle shaft to open and close a throttle bore, and a motor adapted to rotate the secondary throttle shaft for opening and closing the secondary throttle valve. The motor for opening and closing the secondary throttle valve has an output shaft coaxially disposed with the secondary throttle shaft. The output shaft and the secondary throttle shaft are connected by means of a coupling. The secondary throttle shaft is offset from the axis of symmetry of the throttle bore. The secondary throttle valve is divided by the secondary throttle shaft and defines a section which is longer in dimension from the secondary throttle shaft to the end of the secondary throttle valve and another section which is shorter. The longer section is disposed downstream in air flow, so that air flowing through the throttle bore exerts on the secondary throttle valve a force acting to open the same.
