ABSTRACT:
A fuel supply system comprising a transverse partition wall upstream of a throttle valve and having at least one air intake opening therethrough, a spring-loaded metering rotor thereabove which has at least one rotary blade for controlling the opening area of the air intake opening and at least one movable wall upon which is exerted the intake air pressure, the partition wall having at least one stationary radial wall, whereby the stationary and movable walls define a pressure chamber which is variable in volume and into which is introduced the pressure downstream of the transverse partition wall, the pressures upstream and downstream of the transverse wall acting on the opposite surfaces of the movable partition wall so that the rotor is caused to rotate in the direction in which the opening area of the air intake opening is increased and the rotation of the metering rotor is stopped at an angular position at which the force of the bias spring is in equilibrium with the force rotating the metering rotor. Thus the angle of rotation of the metering rotor is in proportion to the flow rate of the intake air. A fuel metering valve has a spool formed integral with a shaft of the metering rotor and meters the fuel in proportion to the angle of rotation of the spool so that the air-fuel ratio can be maintained constant.
