Abstract

The multiple device automatically controls the volume of air passing through it in one direction. Regulation is effected by turning a rotor in a passage (2) equipped with ribs (3a, 3b), the position of the vanes being used to give the desired regulation. There may be a counterweight, acting in only one direction of rotation of the rotor and one air flow direction. Vane position can be determined by the equilibrium between the action of the counterweight and the dynamic component generated by the passage of air at a certain speed.
