Abstract

3026. Michaux, G E. N. March 24, 1914, [Convention date]. Spray carburettors. - Constancy in mixturestrength is obtained by raising the outlet orifice of the fuel nozzle above the fuel level as the air supply is diminished. and vice versa. A piston l actuated through linkages attached to the projection t moves across the inclined indu tion passage e and imparts axial motion to a central tube m, which carries the fuel nozzle o. Both the tube m and fuel nozzle o more with slight friction in contact with the fixed fuel well n fed from the float chamber c. The tube m is actuated from the piston l through two springs s, which permit of relative motion between piston and tube. A tube q forming an extension of the tube m slides in a guide i and controls a port j, through which air is supplied by way of the tube q to the chamber pin which the fuel is sprayed. For slow running, the piston is fully raised to touch the diaphragm f, in which case a shallow conduit g forms the air passage. For full power, the piston is depressed below the lower wall of the induction passage e, and intermediate positions are taken up for " picking up" and normal running.
