Controller with digital signal processing during which the continuous change in the controlled variable is sampled in steps. For the processing it is necessary to change to discrete time operation. If

Device for separating small particles of dirt from the hydraulic fluid based on other particle characteristics apart from the particle size.

If the state variables required for a state controller State variable cannot be measured or are difficult to measure, this can be replaced by monitoring the behaviour of these variables (Figure Z 9).

Interaction between a spring-loaded mass system (e.g. cylinder + oil column + load) and the pressurisation at very low sliding speeds ( Figure S 94 ). The stiction of the system –– which is primarily

The part of a valve , which ensures the desired function through its movements.

whereby the control algorithm is associated with non-linear behaviour, i.e. the input and output for the controller are linked to each other by a non-linear characteristic curve or function.

General : Graphically represented mutual dependency between two operating variables, often with a constant third being used as the parameter. Example: In Figure D79, the flow rate Q is applied to a co

The required filter size is based on the permissible flow resistance of the oil filter at the nominal flow rate. The selection of the filter size is affected by: The selected filtration grade , The fl

Valve with a proportional connection between the input signal and pressure in the working lines (consumer ports). This includes construction designs of proportional pressure-limiting valves and pressu

Pressure valve , which maintains a pressure before its inlet that is normally adjustable using a spring (e.g. to maintain a dynamic pressure).
