Abstract

Die Erfindung betrifft einen Hydrotransformator mit einer Vielzahl von Verdrängerräumen (12) und mit einer Steuerscheibe (20), die um eine Drehachse verdrehbar ist, um eine Pumpwirkung/Motorwirkung des Hydrotransformators (1) zu verstellen, und die Steuerausnehmungen (21-23) aufweist, denen jeweils mehrere Verdrängerräume (12) zugeordnet sind. Die Erfindung zeichnet sich dadurch aus, dass sich die Größe der Verdrängerräume (12) im Betrieb des Hydrotransformators (1), bezogen auf die Drehachse der Steuerscheibe (20), radial, tangential und/oder in Umfangsrichtung, verändert, um die Pumpwirkung/Motorwirkung des Hydrotransformators (1) zu erzielen.
