Digital/analogue converter
Converts digital input signals into analogue output signals, i.e. into a proportional DC voltage. In conjunction with digitised signal processing provided by microelectronics, D/A converters are requi
Operating modes of drives
Drives have not only a driving function, they also provide braking (e.g. deceleration or lowering braking). In addition, the direction of rotation can also be reversed. The combination of these possib
Control diagram
Illustration of the states of the signal element (as signal inputs) and the (as signal outputs) of a system. In doing so, the changes or specifications which are used to trigger or end a process cycle
Bounce-free
When the input signal changes, the output signal switches in a single, unambiguous move from one signal state to the other (DIN 19 237).
Geared pump/motor
Hydraulic pump/motor with two or more gears working together in one housing. They may take the form of an external geared pump/motor , an internal geared pump/motor or an annular gear pump/motor .
Control edge geometry of valves
Design of the necessary form of control edges in hydraulic valves necessary for the respectively desired manner of influencing the flow rate ( fine control ).
Retention rate
Filter cumulative efficiency
Following control valve
Hydraulic valve which creates the difference between the setpoint and actual value and also releases a flow rate proportional to the difference. To this end, the control unit for the valve is connecte
Indirect actuation
If the operating conditions during direct actuation become too unfavourable (e.g. due to excessive pressure , excessive flow rate ), indirect actuation will be chosen, which generally uses a smaller d
Spring accumulator
Hydraulic accumulator on which a spring is used for the pressure load. This solution is only suitable for very small accumulators, as otherwise the spring and therefore the overall dimensions will be
