Claims (4)

Patentansprüche:Patent claims: 1. Axial-Turbopumpe, vorzugsweise zur Verwendung als schnell laufende Hochvakuumpumpe, dadurch gekennzeichnet, daß die Läuferscheiben (2) bzw. Leitkränze aus mehreren aufeinandergeschichteten dünnen, am Umfang gezahnten und einander gleichen Blechringen (1) aufgebaut sind, die derartig gegeneinander verdreht zusammengespannt sind, daß die Zahnflanken aufeinander-. folgender Ringe zur Pumpenachse schrägliegende Einhüllenden ergeben.1. Axial turbo pump, preferably for use as a high-speed high vacuum pump, characterized in that the carrier disks (2) or guide rings are made up of several stacked one on top of the other thin sheet metal rings (1) that are toothed on the circumference and are identical to one another are constructed, which are so twisted against each other clamped together that the tooth flanks on each other. The following rings result in envelopes at an angle to the pump axis. 2. Axial-Turbopumpe nach Anspruch 1, dadurch gekennzeichnet, daß die Einhüllenden gerade sind (Abb. 3 a, 3 b).2. Axial turbo pump according to claim 1, characterized in that the envelopes are straight (Fig. 3 a, 3 b). 3. Axial-Turbopumpe nach Anspruch 1, dadurch gekennzeichnet, daß die Einhüllenden gekrümmt sind (Abb. 3 c).3. Axial turbo pump according to claim 1, characterized in that the envelope is curved are (Fig. 3 c). 4. Axial-Turbopumpe nach den Ansprüchen 1 bis 3, dadurch gekennzeichnet, daß die Form der Blechringe (1) durch Stanzen hergestellt wird.4. Axial turbo pump according to claims 1 to 3, characterized in that the shape of the Sheet metal rings (1) is made by stamping. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
