Abstract
Le rotor (G), constitué d'un corps annulaire (C) pourvu extérieurement d'ailettes radiales flexibles (R) est caractérisé en ce qu'il comprend, en tant que parties intégrantes, des moyens pour l'accouplement rota tif d'une extrémité de l'arbre (A) de la pompe (P), lesquels moyens sont obtenus par estampage simultané du corps annulaire et des ailettes ra diales. The rotor (G), consisting of an annular body (C) provided externally flexible radial fins (R) is characterized in that it comprises, as integral parts, means for rota coupling tif of one end of the shaft (A) of the pump (P), which means are obtained by simultaneous stamping of the annular body and the fins fin diales.
Selon une forme particulièrement simple et économique de réalisation, lesdits moyens sont constitués par une cloison ou nervure (D) traversant diamétralement le perçage du rotor et s'engageant dans une gorge corres pondante que présente l'extrémité de l'arbre. According to a particularly simple and economical embodiment, said means consist of a partition or rib (D) passing through diametrically the rotor bore and engaging in a corresponding groove that the end of the tree presents.
