Signal processing with electronic modules that may be analogue or digital . It is therefore possible to utilise for the signal processing all the features of modern microelectronics related to the sco

High pass filter assembly that measures the pressure oscillations in the drive and controls the downstream damping devices . This assembly can operate mechano-hydraulically (e.g. hydraulic accumulator

Characterises the chemical composition as well as the physical state of a new hydraulic fluid . Here is must be noted that even new oil is never absolutely clean, instead on average it corresponds to

Mixed circuit diagram of the wiring diagram and function chart circuit diagram used as a summary view of the circuit and programmed function of controls and with memory-programmable equipment (DIN 40

Check valve with two blockable inflows and one outflow. The inflow with higher pressure is blocked, the other inflow is connected to the outflow. If both connections have the same pressure, both are c

Devices with a defined form and dimensions as per DIN 1952 and which are used to measure air flows. They may take the form of an orifice ( a ), nozzle ( b ) or Venturi nozzle ( c ) ( Figure N 5) .

Circuit that routes the outlet flow on the piston rod side on a differential cylinder to the inlet on the piston side to increase the flow velocity ( rapid traverse circuit ) (Figure 22) . As a conseq

Volume of fluid which flows through a cross-section in one time unit. In hydraulics the flow rate is generally stated in litres per minute (lpm). For example, filling a 10 litre water bucket at the ta

Feedback of the load pressure in hydrostatic transmissions . Negative load pressure feedback increases damping for the drive, but without any influence on natural frequency or velocity amplification .

The state diagram shows the function sequence of one or more work units and the control technology links of the accompanying structural elements at two coordinates. At one coordinate, the state, e.g.
