Setting device for adjusting lu00c2minas of helical sideward reciprocating pump and helical sideward reciprocating helical sideward reciprocating pump including such a device.The present invention relates to a device for adjustment to adjust the angle of pitch of propeller blades (4) of a pump propeller (1) and a pump propeller incorporating such a device, the device comprises means for adjusting adjustment (5; 25; 35) mounted inside the cube (2) disp Ostos for being axially movable in a direction along the drive shaft (7),The adjustment means (5; 25; 35) being provided with a plurality of grooves of guide (6; 26a, 26b; 36) arranged ring out around the surface; a plurality of fixing means (20) mounted rotationally on the hub (2), each being Kingdom at the blade on a The propeller (4) and is supported at least by a slot guide (6; 26a, 26b; 36),Where each of the fastening means (20) and at least one notch to guide (6; 26a, 26b; 36) which are arranged to interact in such a way that a force applied in the means of attachment (20) is distributed symmetrically around an axis perpendicular to the drive shaft (7) and paral Link to a rotary axis of the fastening means (20); and where the grooves of guide (6; 26a.26b; 36) are arranged to cause, in an axial movement of the means of adjustment (5; 25; 35), the means for fixing (5; 25; 35) rotate about their own axis turntable, by means of which the blade of the propeller (4) is rotated by turn.
