摘要： A carburetor has a carburetor housing in which an air passage and a mixture passage are disposed. A barrel valve controls the air passage and the mixture passage. The barrel valve has a mixture passage section and an air passage section formed therein. The air passage in at least one position of the barrel valve is closed off at least partially by the barrel valve. The air passage in the at least one position of the barrel valve in which the air passage is at least partially closed off by the barrel valve is connected by a connection within the barrel valve with the mixture passage. An internal combustion engine equipped with such a carburetor exhibits excellent running behavior.

摘要： A valve is used with a carburetor, and the carburetor therefor. The valve has a throttle valve and an air valve. The air valve defines an air bore and has a baffle disposed within the air bore. The baffle separates one section of the air bore from another section, and impedes airflow through the air bore during at least some positions of the air valve.

摘要： A carburettor for a two stroke engine includes a flow duct including rich and lean flow passages (160, 150) in parallel, through which, in use, air flows in a flow direction and which are separated by substantially planar partition (130). At least one fuel jet (5) communicates with the rich passage (160) and the partition includes an aperture (140) towards which the fuel jet is directed. A substantially planar butterfly valve (120) is received in the aperture so as to be pivotable between a first position, in which the flow duct is substantially closed and the aperture is substantially open, and a second position, in which the flow duct is substantially open and the aperture is substantially closed. The upstream half of the aperture (140) is defined by upstream semi-annular seating ledge (148) affording an upstream seating surface (151), which is engaged by one of the surfaces of the butterfly valve (120), when it is in the second position, and a first end surface (153), which extends between the upstream seating surface and that surface of the partition which is directed towards the lean passage. The downstream half of the aperture (140) is defined by a downstream semi annular seating ledge (149) affording a downstream seating surface (151), which is engaged by the upper surface of the butterfly valve, when it is in the second position, and a second end surface (161), which extends between the downstream seating surface and that surface of the partition which is directed towards the rich passage. At least one of the upstream semi annular seating ledge, the downstream semi-annular seating and the valve are so shaped that, in use, a pressure differential is created between the rich and lean passages at the upstream and/or downstream edges of the valve, the pressure in the lean passage being higher than that in the rich passage.

摘要： A carburetor for a stratified scavenging two-cycle engine, in which a throttle valve and a air valve are formed in a vale element that is a single cylindrical member in which a throttle through-hole and an air through-hole are diametrically formed and which is rotatably fitted in a body, the mixture passage and the air passage being formed piercing through a body, wherein the height of the body is decreased so as to miniaturize the carburetor as a whole, and the mixture passage 6 and the air passage 9 are formed in a single cylindrical common hole 69 in which the mixture passage 6 and the air passage 9 are partitioned by a partition wall 68.

摘要： A carburetor 9 for feeding separate lean and rich channels 12, 13 of an engine intake duct 14 comprises a body 20 having a mixing passage 22 with an air intake side 24 and an engine outlet side 26. A throttle shutter 16 is rotatable about an axis transverse the mixing passage, and a partition 10 is located within the mixing passage upstream of the throttle shutter. The downstream edge of the partition 10 is adjacent the throttle shutter axis 16A whereby in use of the carburetor the partition defines an extension of the lean and rich channels upstream of the throttle shutter, the partition thus providing substantial isolation between the lean and rich channels for all rotational positions of the throttle shutter. In a preferred embodiment a choke shutter 17 is located upstream of the throttle shutter and is rotatable about a further axis 17 A transverse the mixing passage, the upstream edge of the partition being adjacent to the axis of the choke shutter.
摘要翻译：用于输送发动机进气管道14的分离的贫和富通道12,13的化油器9包括主体20，其具有带有进气侧24和发动机出口侧26的混合通道22。节流阀16可以绕着混合通道横向的轴线旋转，并且隔板10位于在节流闸门上游的混合通道内。分隔件10的下游边缘邻近节流阀16A，由此在使用化油器的情况下，隔板限定了节流闸门上游的稀薄和富裕通道的延伸部分，因此，隔板在精益和富有通道之间提供了实质的隔离对于油门挡板的所有旋转位置。在优选实施例中，扼流闸17位于节流闸门的上游，并且能够绕横向于混合通道的另一轴线17A旋转，隔板的上游边缘与阻风门的轴线相邻。
