    • An air flow meter comprises a main passage for an axial main air flow; an axial subpassage for air flow, disposed in the main passage and formed so that part of the air in the main passage is taken in at an upstream side thereof and flows in the same direction as the axial main air flow; a radial subpassage for air flow, intersecting the axial subpassage at a downstream side of the axial subpassage so that air from the axial subpassage flows into the radial subpassage and is divided into two radial air flows running in different radial directions; the air having passed through the radial subpassage joining the axial main air flow. An air flow sensing means is disposed in the radial subpassage for sensing a flow rate of air therein, and a projection is disposed in the radial subpassage around the intersection of the axial and radial subpassages, for suppressing turbulence of air flow around the intersection.
    • 空气流量计包括用于轴向主空气流的主通道; 设置在主通道中并且形成为使主通道中的空气的一部分在其上游侧被吸入并沿与轴向主空气流相同的方向流动的用于空气流的轴向子通道; 用于空气流的径向子通道,在轴向子通道的下游侧与轴向子通道相交,使得来自轴向子通道的空气流入径向子通道并被分成在不同径向方向上运行的两个径向空气流; 已经通过径向子通道的空气连接轴向主空气流。 气流检测装置设置在径向子通道中,用于感测其中的空气流量,并且在轴向和径向子通道的交点处的径向子通道中设置突起,用于抑制交叉点周围的空气流的紊流。
