Characteristic with averaged hysteresis
Line connecting the signal averages in the (static) characteristic curve for a device where hysteresis is averaged out, i.e. with hysteresis at zero ( Figure M 27 ) (DIN 24 311).
Control unit
the programmed cycle of all control functions in cyclical sequence and can be connected via a bus line with all inputs, outputs, functional units and the program memory.
High speed exhaust valve
Shuttle valve, which is opened by the feed line pressure in the direction of the consumer and releases the exhaust connection when switching due to the consumer pressure ( Figure S 31 ).
Flow rate amplification
input signal and the hydraulic (here flow rate ) at zero load pressure in the range of the primarily linear characteristic (cf. transfer factor ).
High pressure filter
Filter to be installed in the pressure line within a circuit. The housing, therefore, must withstand the nominal pressure associated with the system, although this is not the case for the filter element
Load stiffness
of a hydraulic drive) to yield as little as possible under an external load. Load stiffness for linear drives is mostly stated in N / μm. It can be compared with spring stiffness.
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
Settling time T g
variable defined by the intersections between the first inflection tangent and the abscissa, and the line parallel to the abscissa through the value in the steady state (EDIN 19 226 Part 5).
Controller types
loop controllers, cascade controllers , state controllers , by the degree of complexity: linear controllers, non-linear controllers , status monitors , adaptive controllers . ( Figure R 21 ).
Load pressure difference
at a management or . It is referred to as positive if the inlet pressure is higher than the return line pressure. With synchronizing cylinders , the load pressure difference is equivalent to the load pressure
