Abstract

1. Axial flow fan with a fan wheel (2) having holes through which adjustable-pitch blades (4) are passed and which are sealed by sealing rings (15, 16, 17, 27, 28), the root (11) of each blade (4) being connected by screws (12) to a shaft (5) arranged inside the fan wheel, characterized in that the screws (12) are passed from the fan wheel inside through a flange (14) of shaft (5) into the root (11) of blade (4), that the sealing rings (15, 16, 17, 27, 28) are prestressed radially to the fan wheel (2) by resilient elements and pressed against a sliding face (21) at the root (11) of blade (4) located perpendicular to the line of force of the resilient elements and that the prestress deflection of the resilient elements is greater than the displacement caused by centrifugal forces in the area of the sealing rings (15, 16, 17, 27, 28).
