Hydrostatic machines driven by hydrostatic pumps - has regulator jacks feed via metering valve in return feed of main circuit

摘要

The hydrostatic control circuit uses a group of hydrostatic pumps to drive a hydrostatic machine of which the input and output flows are adjustable. The machine is coupled to a signal-generator of which the signal is transmitted to a regulator in the form of an hydraulic jack, the signal amplitude being a function of operating speed. The signal-generator comprises an hydrostatic pump-motor and is connected to the respective chambers of the relevant regulator by separate hydraulic lines. The regulator is fed by a meter valve located in the return feed of the hydraulic circuit. The output of the meter valve determines the nominal value of the radial velocity of the relevant machine.
