Abstract
PURPOSE: To improve the follow-up performance of a carburetor with stepped fuel discharge, by compressing its accelerator pump in two steps.
CONSTITUTION: A float chamber 13 of carburetor is communicated with a main nozzle (not shown in the figure) through an accelerated fuel pipe 12 equipped with a check valve 15. Above the pipe 12 is set a piston 4 of accelerator pump communicated with a throttle valve (not shown), while below the piston 4 is formed a working chamber 5. Another piston 6 is supported on a piston rod 3 and both pistons 4, 6 have between them an auxiliary chamber 5 which is communicated with the working chamber 5 through a small hole 8 formed on the piston 4. As the piston 4 descends, part of fuel in the working chamber 5 is fed in the auxiliary chamber 7, and the other piston 6 descends due to the action of a spring 10 to force fuel in the auxiliary chamber 7 out to the fuel pipe 12.
