PETROL CARBURETTORS. 2<> taper pin is raisecl. Obviously, the lift of the piston n can be modified by opposing more or less resistance to its movement by the hand-controlled lever r, and in this manner make any necessary correction, as whatever the means employed, it is difficult to obtain a perf eet regula- tion by a single adjustment for all running conditions. It is possible to obtain a constant mixture over a considerable range of speeds by utilizing the varying velocity of the mixture flow to cause a piston, as in the Figs. 25 and 26.—Typical Constant Mixture Single-jet Carburettors with Automatic Variable Pin-regulated Feed. Brotherhood-Crocker carburettor introduced at about this time, to carry with it a taper choke-tube, thus automatically regulating the air supply and simultane- ously by means of a taper pin in the spray nozzle the fuel supply as well, provided the air and fuel ways are accur- ately proportioned in area. In the Westinghouse variable jet carburettor introduced in 1908, the air and spray
