ABSTRACT INTAKE MANIFOLD VARIABLE ATOMIZING VALVE An air-fuel mixture in the proper ratio is delivered by a carburetor to a variable atomizing valve which is positioned inside of the intake manifold by protecting through the main inlet opening on the customary carburetor base mounting face of the intake manifold, The atomizing valve is normally biased by an eccentric spring means to a nearly closed position but opens automatically to any required position in response to engine demand. The valve embodies an interior relatively stationary imperforate barrier sleeve and an exterior relatively movable screen assembly mounted telescopically on the barrier sleeve. The screen assembly consists of an interior comparatively coarse mesh screen surrounded by a fine mesh screen and an exterior rigid cage for the screens, The two concentric screens are in firm contact around their entire circumferences. A bearing intervened with the barrier sleeve and the rigid cage estab- lishes a necessary jump space between the interior screen and the bore of the barrier sleeve so that the incoming fuel charge after turning will impinge with some force on the interior screen, Complete atomization of the engine fuel charge is obtained with many attendant advantages and wetting of the intake manifold with raw fuel droplets is completely avoided. The incoming fuel charge is aimed at the intake ports of the engine, is a cool charge, and travels with velocity.
