    • A vane wheel (1) driven by a shaft (4s) for transferring a gas, comprising vortex flow chambers (9) opening in a direction substantially parallel to the shaft (4s) to receive the gas, to urge the gas in a substantially circumferential direction of the vane wheel (1), and to generate and accelerate a vortex flow of the gas, a vane member has a hub (8) through which the vane member is connected to the shaft (4s), a plurality of vanes (12) each of which extends integrally from the hub (8) in a substantially radial direction of the vane wheel (1) and includes a front surface for urging the gas in the substantially circumferential direction of the vane wheel (1), and a vortex flow chamber wall (10) extending integrally from both of the hub (8) and each of the vanes (12), and a cover (11) contacting with the vortex flow chamber wall (10) to form the vortex flow chambers (9) together with the vortex flow chamber wall (10) and the vanes (12).
    • 由用于传送气体的轴(4s)驱动的叶轮(1),包括在基本上平行于轴(4s)的方向上开口的涡流流动室(9),以便将气体推向基本圆周 叶轮(1)的方向,并且产生并加速气体的涡流,叶片构件具有轮毂(8),叶片构件通过该轮毂(8)连接到轴(4s),多个叶片(12 ),其各自在所述叶轮(1)的大致径向方向上从所述轮毂(8)一体地延伸,并且包括用于沿所述叶轮(1)的大致圆周方向推压所述气体的前表面,以及涡流 一体地从轮毂(8)和每个叶片(12)延伸的室壁(10)和与涡流流动室壁(10)接触以形成涡流室(9)的盖(11)在一起 与涡流流动室壁(10)和叶片(12)。
