Abstract
1487964 Spray carburetters ALFA ROMEO SpA 10 Oct 1974 [10 Oct 1973] 44021/74 Heading F1H [Also in Division F2] A fuel metering orifice 37 in a carburetter is defined by an aperture 38 in a thin wall 36 relative to and against which a further thin wall 35 is slidable to vary the effective flow cross-section of the aperture dependent upon the position of the induction passage air valve 12. The valve 12 is operated in response to operation of the throttle valve 14 by a diaphragm 21 subject to the pressure between the valves or by a mechanical linkage between the valves, Figs. 2 and 3 (not shown), or the air valve (164), Fig. 5 (not shown) may be an eccentrically mounted spring-biased valve. The aperture (127), Fig. 4 (not shown), may be formed in the end-wall (126) of an angularly adjustable hollow plug (121) to provide varying registry with an aperture (129) in a wall (128) mounted for calibration adjustment. Slot apertures (195, 196, 204), Figs. 6 and 7 (not shown), defining variable orifices each supplying a respective induction passage of a carburetter have their effective flow cross-sections controlled by respective angularly movable walls (183, 184, Fig. 6), or by the wall of a hollow cylinder (202, Fig. 7), axially movable within a cylinder (203) defining the apertures. To control the air-fuel ratio of the mixture supplied by the carburetter the emulsion well (142, Figs. 4 and 5), may be vented to the constant level fuel chamber (137) which has vents (154, 155) controlled by respective needle valves (156, 157) operated by a bi-metal strip (158) responsive to engine temperature and a bellows (159) responsive to ambient temperature and pressure, respectively.
