Shock in the pressure fluid due to the release of kinetic energy if the flow rate suddenly stops (e.g. due to closing a valve or a piston moving against a stop). The pressure wave produced in this man

Measure for the usage of a device (e.g. a pump) during a working cycle. The basis for determining this parameter is the sequence diagram for the installation. The utilisation factor plays a role in th

(Discrete) controller , in which the controller output signal is discontinuous despite a continuous input signal (switching controller) Examples: 2-point or 3-point controller (DIN 19 225).

For use in this is a group of continuously adjustable valves, in which a constant input signal brings about a proportional. A distinction is made between mechanical-hydraulic servo valves ( copying va

Pressure at which the safety valve delivers the stroke required for the mass flow to be discharged. The opening pressure is equal to the response pressure (operating conditions) plus the opening press

Hydraulic accumulator with a free-moving piston as a separator between gas and hydraulic fluid (Figure K 19) . Since there is no separating wall made of rubber, the fatigue resistance is greater than

Vane pumps operate according to the Positive displacement principle . The moving vanes, which are guided radially in a rotor and are supported in an eccentric stroke ring (stator), create an increasin

Deals with the theoretical observation of the dynamic behaviour of technical systems in the broadest sense. For example, as a technical system with a certain dynamic performance, which is highly non-l
