Abstract
PURPOSE: To make possible to vary the relative position of a movable inducer by making use of equilibrium to a hydrdynamic torque induced in the movable inducer previously exerted with an initial torque within an impeller portion, when the operation point of the blower shifts to the flow capacity side in which a burble flow arises.
CONSTITUTION: As shown in the drawings, a guide ring 4 can only be moved in the axial directions of and relative to a shaft 1, and a movable inducer 3 is arranged such that is movable in the circumferential direction, or rotatable, relative to the shaft 1 along with an impeller 2 and a cover 9. With this arrangement, in an operating state upon, for example, a large flow copacity an increased hydrodynamic torque induced in the movable inducer 3 causes the latter to rotate rearwards as seen in the rotational direction thereof, and then to be positioned as shown in the drawings, so that a highly burble pressure fluid on the side of airfoil surface Y flows toward the side of an airfoil surface X. Thus, an increased trend of the peeling-off of a boundary later can be prevented. Accordingly, the effective area of flow is reduced and therefore operation at a large flow capacity can be expected.
