    • An air flow measuring device has a throttle portion provided in a first sub-passage, a second sub-passage branched from the first sub-passage at an upstream side of the throttle portion, and a flow amount sensor located in the second sub-passage. The second sub-passage is configured to introduce therein a part of air flowing in the first sub-passage, and an inlet of the second sub-passage is open into the first sub-passage at one side in a first radial direction perpendicular to a flow direction of air flowing in the first sub-passage. Furthermore, the throttle portion is provided to gradually reduce a passage dimension of the first sub-passage in a second radial direction, as toward an outlet of the first sub-passage. Here, the second radial direction is perpendicular to a surface defined by the first radial direction and the flow direction of air in the first sub-passage.
    • 气流测量装置具有设置在第一子通道中的节流部分,在节流部分的上游侧从第一子通道分支的第二子通道和位于第二子通道中的流量传感器 。 第二子通道构造成在其中引入在第一子通道中流动的一部分空气,并且第二子通道的入口在垂直于第一子通道的第一径向方向的一侧向第一子通道开放 在第一子通道中流动的空气的流动方向。 此外,节流部设置成朝向第一子通道的出口逐渐减小第一子通道的沿第二径向的通道尺寸。 这里,第二径向垂直于由第一子通道中的第一径向方向和空气的流动方向限定的表面。

    • The centrifugal impeller includes a plurality of blades (3), a plurality of fluid paths (P) for delivering a fluid from an impeller inlet (1) to an impeller outlet (2), and a shroud (4) and a hub (5) for forming the fluid paths (P). Each of the fluid paths (P) is formed between adjacent two of the blades (3). A curved line (L3) of the shroud (4) curves so as to project toward the hub (5) in a region from a blade inlet (A) to a predetermined position (C) of the blade (3), and the curved line (L3) curves so as to project toward the opposite side of the hub (5) in a region from the predetermined position (C) to a blade outlet (B).
    • 离心式叶轮包括多个叶片(3),用于将流体从叶轮入口(1)输送到叶轮出口(2)的多个流体路径(P)以及护罩(4)和轮毂(5) )用于形成流体路径(P)。 每个流体路径(P)形成在相邻的两个叶片(3)之间。 护罩(4)的曲线(L 3)在从叶片入口(A)到叶片(3)的预定位置(C)的区域中弯曲成朝向轮毂(5)突出,并且 曲线(L 3)在从预定位置(C)到叶片出口(B)的区域中弯曲以朝向轮毂(5)的相对侧突出。
