ABSTRACT:
A fuel supply device, which serves to predetermine a fuel quantity that is proportional to the aspirated air quantity, and also serves to spread the air-fuel mixture. The fuel supply device includes an air metering device, which is arranged in the air intake manifold of the internal combustion engine and activates a fuel metering device, which has a control slit that opens a control groove by a varying amount. The control slit and the control groove are rotatable relative to each other, and the control groove has at least one control edge, which overlaps the control slit and is formed at an angle relative to the axis of rotation. The control slit is arranged in a guide sleeve and the control groove is arranged in a rotatable sleeve mounted in the guide sleeve with the rotatable sleeve being arbitrarily shifted relative to the guide sleeve. A connecting tube is arranged between the rotatable sleeve and the mounting axis of the air metering device, by means of which the metered fuel can be fed to a nozzle arranged on the air flow rate meter. For a better mixture spreading effect, air can be fed to the metered fuel through a filter composed of a fine-meshed web.
