ABSTRACT:
An improved vacuum operated air valve for incorporation into the idle fuel port of an automotive carburetor. The valve includes a valve seat having an inner conically-shaped area and a surrounding planar area. The valve member includes an axially oriented stem and a flat radially-extending head, an outer end surface of which overlies the valve seat surfaces, whereby opening the valve to a very minute axial displacement opens a substantial venting area, increasing the sensitivity of the valve.
