APERFEICOAMENTOS NOS DISPOSITIVOS DE CARBURACAO

摘要

A carburettor for an internal combustion engine comprises an air valve and a driver-actuatable throttle in an induction pipe. The air valve controls proportioning means metering the flow rate of fuel drawn into the induction pipe downstream of the main throttle means via a discharge orifice. A fuel pressure regulator is disposed between the fuel proportioning means and the discharge orifice for controlling the pressure of the fuel discharged into the induction pipe and comprises a valve actuated by a diaphragm one face of which limits a control chamber communicated with that portion of the induction pipe located between the throttle and the air valve. The other surface is subjected to the fuel pressure prevailing upstream of the valve.
