Actuation device which operates via elements moved mechanically (e.g. actuation of cams by valves).

With multi-loop feedback control circuits, several physical variables are recorded during the process and processed in accordance with various algorithms . These include cascaded (multi loop) control

Digital computer system where a shared functional unit controls two or more central units, each of which has at least one processor. (EDIN 44 300, Part 5).

Applies to elements (step control elements) which assign to several value ranges for an input signal in the steady state the same number of different values as for the . Elements featuring two-point p

Discrete controllers which, when a certain control deviation is exceeded, change the suddenly at various stages (DIN 19 225). Example based on a two-point controller: temperature control via a device

Hydraulic drive system in which several circuits operate separated from each other, with each having a pump and associated pressure-limiting valve . These kinds of multi-circuit systems may be designe

Multiple pump whose units supply separate circuits with a pressure-limiting valve because their working cycles overlap. If a constant pump is involved, the installed power will be equal to the total f

Biologically degradable, i.e. environmentally-friendly hydraulic fluid. based on natural base oils. Besides the desired environmentally-friendly properties, rapeseed oil displays properties such as po

Factors influencing the structure and function of hydraulic systems that result, amongst other things, from the task formulation. This includes environmental conditions, such as the range of the worki

Time function which produces a general increase or decrease to a specified end value when moving and braking ( Figure R 9 ). As the ramp is equal to the integral of a step function over time, the time
