<p>The invention refers to carburettors for crankcase scavenged two-stroke engines utilizing additional air that is led via scavenging ducts into the combustion chamber of the engine. More particularly it refers to a valve arrangement at the inlet of the additional air duct (3; 23). The advantage of the novel valve is that it is turned around a shaft (6; 26) located outside the additional air duct, whereby it will not disturb the flow of air into this. The valve is controlled synchronically by the engine throttling by means of a link rod arrangement, or an eccentric sheave push rod construction, in both cases with mechanical connection to the turning shaft of the throttle valve.</p> |
