    • A throttle valve for adjusting an amount of intake air to an internal combustion engine includes throttle shafts disposed in an intake air passage perpendicularly across the longitudinal axis of the air passage, and first and second valve members mounted on the throttle shafts for opening/closing about the throttle shafts independently of each other. By these first and second valve members, there are formed main air passages for causing air to flow in the intake air passage along the longitudinal axis of the intake air passage toward the internal combustion engine and auxiliary intake air passages for causing air to flow in the intake air passage substantially perpendicularly across the longitudinal axis of the air passage.
    • 用于调节内燃机的进气量的节流阀包括设置在进气通道中的节流轴,垂直于空气通道的纵向轴线,以及安装在节流轴上的第一和第二阀构件,用于打开/关闭约 油门轴彼此独立。 通过这些第一和第二阀构件,形成有主空气通道,用于使空气沿着进气通道的纵向轴线朝向内燃机在进气通道中流动,并且辅助进气通道用于使空气在 进气通道基本上垂直于空气通道的纵向轴线。
