Hybrid accumulator
from a combination of steel and plastic to save weight. Suitable for use in vehicles, particularly with a view to energy recovery through braking.
Leakage line
returns leaked fluid to the container. Its dimensions should ensure this is possible at all times with hardly any pressure — even at low temperatures.
Output unit
Function unit within a digital computer system with which the system outputs data - e.g. calculated results - to the exterior (EDIN 44 300 Part 5).
Open-centre position
tional valves, in the centre position, all ports can be connected to one another –– and therefore with the workflow (requires negative overlap).
Bleeding
hydraulic fluid removal of the air carried and separated out. This must take place at the highest point with the aid of bleed screws or bleed valves.
Controller concepts
I-controller and a D-controller. P-T1-controller [PT1-controller]: P-controller with P-T2-controller [PT2-controller]: P-controller with 2nd order time delay. These controllers work consistently in a single loop
Barometric feedback
the position of the control spool of a continuously adjustable valve by centring the control spool with spring action (item 8 and 9 (Figure B 3) ).
Fail safe
Safety circuit for the elimination of a faulty device or part of a control system with redundant circuits. The signal is generally triggered by measures for fault detection .
Binary signal
A binary signal (two-point signal) is a single-parameter digital signal with only two value ranges for the signal parameter, e.g. O and L (DIN 19 226).
Pressure/flow rate diagram
On continuously adjustable pressure valves : dependency of the pressure on the flow rate with the input signal as a parameter (E DIN 24 311) (Figure D 81) .
