涡流鼓风机
摘要：
本发明提供一种不提高噪音而压力高的涡流鼓风机。本发明使朝旋转方向间隔在设置于静止流路(3)上的喷出口(9)和吸入口(8)之间的隔离壁(10)的喷出侧形状与叶片(4a)形状相同，为隔离壁(10)不与喷出口(9)重叠的位置关系。这是吸入侧的压力变动比喷出侧高，噪音由吸入侧决定。
摘要（英）：

The invention provides a high-pressure turbo fan without improving noise. In the invention, the shape of the spray side of dividing walls (10) arranged between a spray orifice (9) and a suction port (8) on a static fluid passage (13) at intervals towards the revolving direction is the same as the shape of a vane (4a), and the shape has the position relation that the dividing walls (10) are not lapped with the spray orifice (9). The pressure change of the suction side is higher than that of the spray side, and the noise is decided by the suction side.
