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.
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.
