Description

  •
    dernden Maschinendrehzahlen geringe Schwankungen des Arbeitsmittelflusses auftreten. In der Praxis stellen diese
    nicht an der Ventilspindel 17a vorbeifließen, und in der Kammer 27a baut sich ein Druck auf, so daß das Rückschlagventil 16a nach links (gemäß Fig. 3) verschoben und da-
    beschrieben worden ist.
