IC engine intake manifold variable atomising valve - comprises barrier sleeve on which mesh screen assembly is telescopically mounted, with jump space between interior screen and sleeve bore

摘要

The variable atomising valve is positioned inside the intake manifold and is normally biased by an eccentric spring to a nearly closed position. The valve comprises an interior relatively stationary imperforate barrier sleeve on which an exterior screen assembly is telescopically mounted. 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 circumference. A bearing intervened with the barrier sleeve and the rigid cage establishes a necessary jump space between the interior screen and the sleeve bore.
