Abstract
A method is provided for fitting a butterfly valve on the slotted shaft of a carburetor body. The slot is first of all oriented parallel to the axis of the duct. Then one edge of the butterfly valve is gripped by a gripping member and is inserted as far as its final position by moving the member along the axis of the duct. The unit formed by the butterfly valve and the shaft is rotated as far as the position in which the butterfly valve closes the duct by exerting a force with the gripping member and a retaining torque with a motor.
