Part of the description of a linear, time-invariant transfer element whereby the phase-frequency response represents the frequency-dependent element of the angle through which an is shifted in relatio

Hydraulic pump with constant geometric displacement V 1 for each revolution and therefore a constant delivery flow Q 1 at constant drive speed n 1: Q 1 = V 1 · n 1.

The reference variable in a control or is a variable not affected directly by the related control or feedback control that is provided to the open loop control system or the from the exterior and that

As new mineral oil is most definitely not pure (generally contamination class 6...7 according to NAS 1638), it should be filtered on filling the tank. Filler filters and breather filters comprise an a

An analogue-digital converter converts an analogue input signal (a DC voltage) into a digital output signal, i.e. into a proportional number. The quantisation error caused by the stepwise digitisation

Ability of a hydraulic fluid to cover the surface over which it is distributed to a greater or lesser degree. Hydraulic fluids with good wetting ability adhere better to the surface. As a consequence

Sum of losses arising in a fluid system. It is comprised of the pressure losses caused by mechanical and hydraulic friction and flow losses , leakage losses , throttle losses , which generally constit

Non-contact seals , which are characterised by a final distance between sealing surfaces, in which the working medium (against which it is to be sealed) is located. The geometry of the sealing gap (si

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

Example based on a three-point controller: temperature control for heating and ventilation based on three values associated with the actuator with mechanically controlled valve such as ventilation val
