Continuously adjustable flow valve
Valve with a proportional connection between the input signal and the flow rate in a working line (consumer port) and in one effective direction. This includes construction designs of proportional flow
Program module
which can be delimited in terms of its allotted task or structure. A control : Consequence associated with control instructions for a self-contained application-based function (as per DIN 19 237).
Load stiffness
an external load. Load stiffness for linear drives is mostly stated in N / μm. It can be compared with spring stiffness.
Flow rate/pressure characteristic
In the case of continuously adjustable valves: Dependence of the flow rate on the load pressure with the input signal as a parameter (DIN 24 311). The graphical representation is the flow rate/pressure
Micro-hydraulics
Widely used term, although not formally standardised or defined, for hydraulic components with nominal widths of up to around 3 mm and flow rates of up to around 20 l/min. Pressures of up to around 300
Available force
derived from the piston area A and the pressure p, having subtracted the friction forces F 2R associated with the seals and guide.
Return line
Line to feed the hydraulic fluid back to the container after the energy has been transferred. As with the Return line filter it must be designed according to the largest flow rate and not according to
Telescopic cylinder
Cylinder with two or more pistons (pull-outs) which enter into one another in a telescopic manner ( Figure T 8 ). The telescopic cylinder allows high strokes in small installation spaces (slightly longer
Electronic signal processing
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 scope
Minutes
safe and uninterrupted transfer of information between functional groups of an EDVA in accordance with the required functions. Minutes contain specifications on the transfer code, error control, the message
