ABSTRACT:
A fitting is installed on the vent system of a carburetor to shield the last opening of the vent system from dynamic pressures caused by wind currents around this opening. This fitting in its simplest form is a plastic tubing "T", which is installed in the end of the vent tubing of the carburetor. It has been found that this fitting is effective in reducing the dynamic pressure effects on the carburetor internal reference pressure. It has also been found that a "T" having a larger diameter cross hole than perpendicular hole is more effective in reducing the dynamic pressure effects on carburetor reference pressure.
