Abstract

A blade wheel consisting of sheet metal for use in motor vehicle refrigerant pumps has blades that are cut out of a disk and pitched and base disk segments that lie adjacent to the blades and remain between the latter. The blade wheel is formed by at least two different blade wheel elements which are provided with cut out, pitched blades, are interconnected in a fixed manner and are arranged so that their respective base disk segments are offset in relation to one another, forming a gap therebetween, the elements thus forming a common bottom disk. A hub sleeve is provided in the center of one of these blade wheel elements (the hub disk), and the center of the other blade wheel element or elements (the bore disk or disks) is provided with a hub sleeve receiving bore, which can be pushed onto the casing of the hub sleeve.
