    摘要： A carburetor, for use in association with a liquid fuel, comprising a barrel means having bore-defining wall means, defining a bore therethrough, a central carburetor axis, an upstream end and a downstream end, an annular ridge forming a constriction in the barrel means, a dissipator body member of generally elongated globular pear-like shape having a maximum cross-section transverse to the barrel means complementary to and downstream of the constriction, the body member being mounted coaxially with the carburetor axis, fuel dissipating passageways through the body member for delivering fuel to the outer surface thereof downstream of the ridge, the ridge and the dissipator body member being movable relative to each other, to establish an annular air passage between the body member, and the downstream side of the ridge, and, fuel line means connecting the fuel dissipating passageways for receiving liquid fuel.

    摘要： A variable venturi carburetor comprises an auxiliary intake air passage, an auxiliary variable venturi and a non-adjustable nozzle portion, in addition to a main intake air passage, a main variable venturi and an adjustable nozzle portion. If the amount of intake air is small as when the engine is being idled, intake air is passed mainly through the auxiliary variable venturi to generate vacuum sufficiently high to jet fuel into the auxiliary intake passage through the non-adjustable nozzle portion. If the amount of intake air is great as when the engine is running under a heavy load, intake air is passed mainly through the main variable venturi. Since two venturis are formed, it is possible to smoothly increase the amount of fuel to be jetted into the intake passage over a wide engine operating condition.

    摘要翻译： 除了主进气通道，主可变文丘里管和可调喷嘴部分之外，可变文丘里化油器包括辅助进气通道，辅助可变文丘里管和不可调喷嘴部分。 如果当发动机空转时进气量小，则进气主要通过辅助可变文丘里管，以产生足够高的真空，从而通过不可调节的喷嘴部分将燃料喷射到辅助进气通道中。 如果当发动机在重载下运行时进气量大，则进气主要通过主可变文丘里管。 由于形成了两个通风口，因此能够在较宽的发动机运转状况下平稳地增加喷射到进气通路内的燃料量。

    摘要： A carburetor for an internal combustion engine comprises a combustion air intake duct, a valve in the duct for controlling the air flow through the duct, a fuel flow regulator in the valve for controlling fuel flow through a downstream portion of the valve in dependence on the air flow, and a turbine associated with the fuel flow regulator and driven by the exhaust gases of the engine, the turbine having a rotating tubular hub extending through the valve and surrounding the fuel flow regulator, the tubular hub being connected to the fuel outlet through the valve.
