ABSTRACT:
An idling device for a carburettor having an emulsion channel with a feed nozzle, most advantageously, a de Laval nozzle, constituting the smallest section size of the emulsion channel and a concentric port surrounding the nozzle which feeds additional air from over the throttle of the carburettor by a connection channel. The emulsion channel possesses a measurement section controlled by a needle which feeds additional air from the connection channel and at times an inlet of air from the connection channel for blocking fuel outflow. The air inlet is opened by a valve when the negative pressure under the throttle is higher than the negative pressure during idling of the engine.
