Abstract

Offenbart ist ein Hydrotransformator mit einem Rotor, in dem eine Vielzahl von Verdrängern geführt ist. Die die Verdränger aufnehmenden Verdrängerräume sind über eine Steuereinrichtung mit zumindest drei Steuerfenstern mit einem Arbeitsanschluß, einem Versorgungsanschluß oder einem Tankanschluß verbindbar. Die Steuereinheit hat einen Steuerkörper, in dem zumindest zwei der Steuerfenster radial versetzt zu den Verdrängerräumen ausgebildet sind.Disclosed is a hydrotransformer with a rotor, in which a large number of displacers is guided. The the Displacer-absorbing displacement spaces are above one Control device with at least three control windows a work connection, a supply connection or a Connectable tank connection. The control unit has a control body in which at least two of the control windows are radial are offset to the displacement rooms.
