EMI2.1
Steuerung nicht stark abgedrossett wird,'die Bewegungskraft für den Steuerkolben auch nach der wohnung des Umströmweges gross genug sein, um, die Gewichtswirkung zu überwinden und

nach Fig. 5 dargestellt-dadurch erreicht werden, dass die treibende Fläche der Steuerkolbens beim Umsteuern in dem gleichen Verhältnis grösser wird, wie die Arbeitskolbenfläche.
EMI2.3
1.
Verfahren zur selbsttätigen Steuerung von hydraulischen Arbeitsmaschinen mit zwei oder mehreren stufenartig zunehmenden Kolbenflächen, darin bestehend, dass. zur Verstellung der Steuerungsorgane die durch den grösseren oder kleineren Arbeitswiderstand eintretende Druckzunahme oder Druckzunahme der Betriebsflüssigkeit im Zylinderraum der betreffenden Druckstufe (in welchem der zugehörige Kolben oder die betreffende Kolbenfläche arbeitet) nutzbar gemacht wird.

EMI2.1
Control is not severely throttled, 'the motive force for the control piston, even after the flow around the dwelling, be large enough to overcome the weight effect and
EMI2.2
According to FIG. 5, this can be achieved in that the driving surface of the control piston when reversing becomes larger in the same ratio as the working piston surface.
EMI2.3
1.
A method for the automatic control of hydraulic machines with two or more piston surfaces increasing in stages, consisting in that. To adjust the control organs, the pressure increase or pressure increase of the operating fluid in the cylinder space of the relevant pressure stage (in which the associated piston or the relevant piston surface works) is made usable.
