Abstract
The fuel flow control device is screwed in the tapped hole (3) of the carburettor (4) for the idling nozzle. A fuel line (20) connects the carburettor float housing to the tapped hole (3). In addition a vacuum line (21) is arranged between the carburation chamber and the fuel-air mixture inlet of the engine. The device has a closing body (17) movable in a chamber between two valve seats (8, 12), the actuating means (25) of which body are designed in such a way that when the engine is idling none of the valve seats (8, 12) is closed and that the first of the valve seats is closed at increased engine speed when the carburettor valve flap (23) is opened, whilst the closing body (17) rests on the second valve seat (12) when the engine speed is reduced due to sudden closure of the carburettor valve flap (23). Due to the fact that the full quantity of fuel can flow to the engine by way of an orifice (9) only when idling and the flow is interrupted or reduced in the case of a high or suddenly reduced speed, the fuel consumption can be reduced and combustion conditions improved.
