Abstract
2052. Lewis, E. W. Jan. 27. Gas or explosive-vapour engines, carburetting in. The carburetter maintains a mixture of constant strength, or of other proportions at varying speeds. Mounted in the body of the carburetter is an adjustable piston or other valve F, having a depending sleeve F<4> extending into the air-supply chamber B. The piston valve is provided with conveniently-shaped ports F<2>, which open into the mixing-chamber when they rise above the stationary sleeve A<2>, the projecting sleeve F<4> having inclined ports which open into the interior of the piston valve when uncovered by the central partition A<3>. The sleeve F<4> is tapered internally to vary the velocity of the air current passing the hydrocarbon spraying-nozzle C. A cylindrical valve E' regulates the supply of mixture to the engine through the outlet E. The rod G passing through the head of the carburetter indicates the position of the piston valve. If preferred, the spraying- nozzle may be controlled by a valve formed by a downward extension of the rod G, the valve having helical or inclined grooves deepening towards the base. The spraying-nozzle may also be tapered, in which case the bore of the sleeve F<4> is made cylindrical.
