Abstract
PURPOSE: To reduce the blocking of an air flow casued by the adjustment of an angle of a movable impeller by a method wherein an angle of air flow blown by a ventilator is adjusted by taking advantage of the sucking action of an air flow to the direction of the rear of the movable impeller in order to reduce the increase in fluid resistance.
CONSTITUTION: If an adjusting lever 7 is turned counter-clockwise and inclined upward to make smaller an opening angle of parabolic movable impellers 2, 3, the air sent from a fan 9 flows in a direction controlled by the imperllers 2, 3, or a concentrated direction. In this case, the flow in the neighborhood of the rear of the movable impellers 2, 3 is sucked to the part or whole rear surface of the impeller corresponding to its angle since negative pressure is produced on the convex portion of the impeller. As a result, the outgoing flow from the ventilator is controlled by the movable impellers 2, 3 and inclined much than the angle being controlled, so that there occurs a flow speed distribution centralized toward the axial direction resulting in a strong directional flow which is extremely centralized.
