An impeller include a substantially cylindrical impeller body with an internal flow path connecting between an inlet opening through a first end surface and an outlet opening through a circumferential surface; and a balance weight embedded in the impeller body. The balance weight has a vertically-elongated shape in which its height in a cylindrical axis direction is larger than its thickness in a radial direction. The vertically- elongated balance weight is embedded in a circumferential section of the cylindrical impeller body.

L'invention concerne une roue à aubes comportant un corps généralement cylindrique de roue à aubes doté dun passage intérieur découlement servant à relier une entrée ménagée dans une surface dextrémité et une sortie ménagée dans la surface périphérique et une masselotte déquilibrage noyée dans le corps de roue à aubes. La masselotte déquilibrage est configurée avec une forme verticale dont la hauteur dans la direction axiale du corps cylindrique de roue à aubes est supérieure à son épaisseur dans la direction radiale. La masselotte verticale déquilibrage est noyée dans le corps cylindrique de roue à aubes au niveau de son bord périphérique.
