The terms covers not only the hydrostatic drive associated with a load, but also more generally the chain of effects involving hydraulic pump control hydraulic motor ( cylinder ), including the associated

Directional valve with six ports: In addition to the four ports A, B, P and T, in the centre position, a continuous line is formed for the flow rate to downstream consumers ( parallel connection ( Figure

Change in the output signal over time for a rising function with a pre-defined rate of change on the input signal. To depict this situation the output signal xa can be plotted in relation to the rate of

Hydraulic drive system in which several circuits operate separated from each other, with each having a pump and associated pressure-limiting valve . These kinds of multi-circuit systems may be designed

superimposed interference. They are either part of other measuring instruments (e.g. measuring amplifier with carrier frequency ) or independent devices. Filters often required are the high pass filter or the

Conical functional element fixed in the housing in radial piston machines with the task of feeding in suction oil and feeding out the pressure oil and simultaneously reversing the rotating piston chambers

pressure actuation occurs if the hydraulic pressure acts directly on the actuating element, while with indirect actuation the pressure acts on the actuation area via the pilot valve .

and counted using automatic counting devices. The result is a profile of contamination in accordance with NAS 1698 or ISO 4406. The term residual contamination should no longer be used and is to be replaced

swelling, to complete dissolution of the elastomer. If the DVI of the intended hydraulic fluid is known, with the aid of diagrams it is possible to determine the expected volume change (Figure D 20) .

instrument which determines pressure by "weighing" it whereby the force on the piston is compared with the force exerted by calibrated weights. In order to eliminate friction, a motor is used to rotate
