[origin: EP0033819A2] 1. Centrifugal wheel for jet equipment with a guiding disc wheel and with scoops (1), fixed on to the guiding disc wheel with the help of stretching elements as stops, each of which is constructed on its front and rear side uniformly, symmetrically to its longitudinal axis (B-B) and to a transverse axis (A-A) running vertically to the longitudinal axis (B-B) in the plane of the scoop, and which has recesses (4), for the reception of the stretching elements, which are provided in rib-shaped side edges (3) of the scoops (1) in pairs in the manner of a mirror image at a distance from the transverse axis (A-A), characterized in that in each rib-shaped side edge (3) there are provided, not only on the front side but also on the rear side, two recesses (4) in the manner of a mirror image at a distance from the transverse axis (A-A), of which recesses (4) provided on the front or the rear side, only those on the same side of the transverse axis (A-A) accommodate the stretching elements.
