A groove (31b) has a width narrower than the diameter of the master pin (22).

The choice of the coupling is conditioned by the diameter of the motor axle and the diameter of the propeller shaft.

Bushings can be plastic, as long as they fit the axis diameter.

A free end edge of every wing (2.1, 2.2) is at a distance of one half of the centre shaft (1) diameter from its surface.

The shorter part of every supporting rib (4) exceeds the free end wing (2.1, 2.2) which is fastened on the opposite part of the centre shaft diameter (1).

The wrist pin is formed of a preselected diameter.

The wind-up spindle (130) includes an adjustment mechanism (150) for varying the outer diameter Do of the wind-up spindle (130) from an initial outer diameter DOI to a final outer diameter Do which is larger than the initial outer diameter DOII

The outer diameter is equal to or smaller than the minor diameter of the distal section of the shaft.

The diameter of the flight of the screw vane decreases along the length of the shaft towards a forward end of the shaft in cooperation with tapering of the diameter of the compaction compartment.

The reference axis is perpendicular to the reference plane and concentric with the reference diameter of the cap.

The reference axis is perpendicular to the reference plane and passes through the centre of the 13,10 mm cap diameter.
