    • A staged multi-barrel carburetor (C) has two air induction passages (P) and first and second throttle valves (T1,T2) one of which is positioned in each of the respective induction passages. The first throttle valve (T1) is operable to open prior to the second throttle valve (T2) opening, and a countershaft (CS) is interconnected with the first throttle valve for rotation therewith as it opens and closes. The countershaft is interconnected (1) with the second throttle valve to open it as the first throttle valve opens, but not until the first throttle valve has opened to a predetermined open position (15). Opening movement of the second throttle valve, after the first throttle valve has opened to its predetermined open position, is delayed (21) if engine vacuum exceeds a predetermined level thereby to prevent lags in engine performance which may occur during engine acceleration.

    • An air-fuel mixture intake apparatus for internal combustion engines includes a two-barrel carburetor having a primary venturi for supplying an air-fuel mixture into a combustion chamber under all loads and a secondary venturi for supplying an air-fuel mixture into the combustion chamber under medium and high loads. The primary venturi is of a fixed cross section and the secondary venturi is of a variable cross section. A vacuum-operated actuator controls operation of a secondary throttle valve in response to a vacuum developed in the primary venturi and subsequently in the secondary venturi. The secondary throttle valve is interlinked with a primary throttle valve by a linkage mechanism such that the secondary throttle valve is allowed to open when the primary throttle valve opens to a predetermined degree with the maximum opening of the secondary throttle valve being variably controlled by the opening of the primary throttle valve after the latter has opened beyond the predetermined degree. A delay valve is disposed in a primary vacuum signal passageway or a common vacuum signal passageway connected to a vacuum chamber of the vacuum-operated actuator to delay an air flow through the passageway toward a vacuum pickup probe in the primary venturi. The secondary throttle valve may be mounted on a shaft displaced downstream off the geometric center of the secondary throttle valve.
    • 一种用于内燃机的空气燃料混合物进气装置,包括一个双桶式化油器,它具有一个主文丘里管,用于将空气燃料混合物全部负载地供入燃烧室;以及一个二次文丘里管,用于将空气 - 燃料混合物供入燃烧室 在中高负荷下。 主文丘里管具有固定的横截面,而二次文丘里管具有可变截面。 真空操作的致动器响应于在主文丘里管中随后在第二文丘里管中形成的真空而控制次级节流阀的操作。 次级节流阀通过联动机构与主节气门相互连接,使得当主节流阀打开至预定程度时允许二次节气门打开,同时二次节气门的最大开度由开口可变地控制 的主节流阀在其开启超过预定程度之后。 延迟阀设置在与真空操作的致动器的真空室连接的初级真空信号通道或公共真空信号通道中,以将空气流通过通道朝向主文丘里管中的真空拾取探头。 次级节流阀可以安装在从次级节流阀的几何中心下游排出的轴上。

    • A carburetor assembly has primary and secondary venturi passages to supply a lean mixture to main combustion chambers of an engine, and has an auxiliary venturi passage to supply a rich mixture to auxiliary combustion chambers of the engine. A throttle valve in each passage is provided with a shaft, and the shaft for the primary throttle valve projects through a hollow hub on the carburetor body. Several members and springs are mounted on the hub and serve to control turning movement of all throttle shafts during various operating conditions of the engine. A link is pivotally connected at one end to an arm which turns with the primary throttle valve and is pivotally connected at the other end to an arm which turns with the auxiliary throttle valve. An angular adjustment is provided between the auxiliary throttle valve and its respective arm. The geometric relationships of the link and arms are such as to provide the desired coordinated movement between the throttle valves.
    • 化油器组件具有主要和次要文丘里通道,用于向发动机的主燃烧室提供贫混合物,并且具有辅助文丘里通道,以向发动机的辅助燃烧室提供浓混合物。 每个通道中的节流阀设有轴,主节流阀的轴通过化油器主体上的中空轮毂突出。 几个构件和弹簧安装在轮毂上,用于在发动机的各种操作条件期间控制所有节气门轴的转动。 连杆在一端枢转地连接到与主节流阀一起转动的臂,并且在另一端枢转地连接到与辅助节流阀一起转动的臂。 在辅助节流阀及其相应的臂之间提供角度调整。 连杆和臂的几何关系是提供节流阀之间所需的协调运动。
