摘要： 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.

摘要： Flange assembly (56) for supporting a structure that provides scavenging air supply to an internal combustion engine (40) at the carburetor (42) to the engine. The assembly includes a thin-body flange (58) that is configured to be abuttingly installed upon an end surface (48) of the carburetor. The carburetor has its combustion air intake (50) or port exposed at an outer surface for intaking air for the combustion process. The thin construction of the flange enables advantageous positioning of the adaptive flange. The relative dimensioning of the thin-body flange (58) also contributes to its low-impact as a modification to air inlet arrangement. A combustion air aperture (60) is provided that extends through the thin-body flange. The combustion air aperture (60) is located in the flange for alignment with the combustion air intake. By this alignment, fluid communication is established across the flange and into the carburetor when the flange is abuttingly installed upon the carburetor. A scavenging air aperture (64) also extends through the thin-body flange and is spaced apart from the combustion air aperture. A valve assembly (76) is operatively coupled to the thin-body flange and has a valve element (78) positioned at the scavenging air aperture (64) for opening and closing the scavenging air aperture.
