Title
(DE) HYDRODYNAMISCHE BAUEINHEIT
(EN) HYDRODYNAMIC COMPONENT
(FR) COMPOSANT HYDRODYNAMIQUE
Abstract
(DE)
Die Erfindung betrifft ein hydrodynamisches Bauelement mit mindestens zwei rotierenden Schaufelrädern, welche einen Arbeitsraum für einen Arbeitskreislauf bilden; mit einem, mit dem Zulauf zum Arbeitsraum und einem Ablauf vom Arbeitsraum gekoppelten geschlossenen Kreislauf. Die Erfindung ist gekennzeichnet durch das folgende Merkmal: der geschlossene Kreislauf ist druckdicht.

(EN)
The invention relates to a hydrodynamic component with at least two rotating impellers, forming a working chamber, for a working circuit, comprising a closed circuit coupled to the inlet to the working chamber and the outlet from the working chamber. The invention is characterised in that the closed circuit is pressure-tight.

(FR)
L'invention concerne un composant hydrodynamique comprenant au moins deux pompes, qui forment un espace de travail pour un circuit de travail, et un circuit fermé couplé à l'entrée de l'espace de travail et à une sortie de cet espace. Cette invention est caractérisée en ce que ledit circuit fermé est étanche à pression.
