Integrated electronics
The expression is used for hydraulic components where the electronic control is integrated within the housing for the device. It mainly applies to proportional valves and servo valves (Figure I 15) .
Binary data processors
Systems in which only binary signals are transferred. They can contain, along with discontinuous two-point elements, also continuous elements provided the binary character of the overall system is ret
Flow rate/signal characteristic curve
In the case of continuously adjustable directional valves and flow control valves: Dependence of the flow rate on the input signal given an constant valve pressure difference (DIN 24 311) ( Figure V 3
Differential cylinder
Double-acting cylinder with one-sided piston rod in which the ratio of the piston area AK to the annular area on the piston rod side is essential for the function of the fluid-related circuit (CETOP R
Flow resistance
Resistance, which a fluid subject to friction must overcome when flowing through and valves . It is noticeable in the form of a pressure drop ( pressure loss ). The flow resistance comprises frictiona
Displacement V 2
The displacement volume taken on by a hydraulic motor during a revolution ( set geometric displacement ). It may be constant or variable, depending on the motor construction type.
Oil cooler
In order to keep the operating temperature of oil-hydraulic systems as constant as possible, it is necessary to use an oil cooler to dissipate any heat losses that cannot escape through thermal radiat
Piston
The part of a hydraulic cylinder upon which the pressure of the medium acts and thereby generates a compressive force. F K = p 1 · A K — p 2 · A R Since friction occurs during the piston movement (par
