Abstract (en)
[origin: WO2006137765A1] The present invention relates to an adjustment device for adjusting the pitch angle of the propeller blades (4) of a propeller pump (1) and a propeller pump incorporating such a device. The adjustment device comprises adjustment means (5; 25; 35) mounted within the hub (2) arranged to be axially movable in a direction along the drive shaft (7), the adjustment means (5; 25; 35) being provided with a plurality of guide slots (6; 26a, 26b; 36) arranged at circumferential spacings around the surface; a plurality of attachment means (20) rotationally mounted in the hub (2), each being fixedly attached to a propeller blade (4) and supported by at least one guide slot (6; 26a, 26b; 36), wherein each attachment means (20) and the corresponding at least one guide slot (6; 26a, 26b; 36) are arranged to interact such that a force applied on the attachment means (20) is distributed symmetrically about an axis perpendicular to the drive shaft (7) and parallel with a rotational axis of the attachment means (20); and wherein the guide slots (6; 26a, 26b; 36) are arranged to, at an axial movement of the adjustment means (5; 25; 35), cause the attachment means (5; 25; 35) to rotate about its own rotational axis, whereby the propeller blade (4) in turn is rotated.
