Abstract: A vehicle carburetor includes a mixing chamber for finely atomizing fuel charges and a pressure responsive pneumatic relay valve for automatically terminating the flow of fuel to the air and fuel-mixing chamber in response to vehicle deceleration. The relay valve is physically separated from the mixing chamber and operates to quickly cut off the supply of fuel when there is a temporary lack of demand for the fuel in order to minimize air pollution and smog effects. Fuel droplets trapped in corrugations on the mixing chamber wall are blasted by an inducted air stream to atomize the fuel.
