Abstract
A carburetor for an internal combustion engine having an intake manifold includes a hollow air control valve, preferably conical, formed by outer and inner hollow valve members having mating surfaces of revolution about an axis. The inner valve member confines a coaxial internal mixing chamber having a cross section increasing in the direction away from the mating surfaces and terminating in an open end extending toward the intake manifold. The valve members are mounted to intercept air inflow into the intake manifold with the valve members being turnable relative to each other about the axis to change the overlap of respective openings and thereby vary the constriction of air flow at the overlaps to control the rate of air flow into the intake manifold. The respective openings are relatively disposed to direct air flow through each overlap with a transverse component of air flow offset from the direction toward the axis, thereby causing a swirling of air within the mixing chamber. Liquid fuel is introduced into air swirling within said mixing chamber.
