Fire-resistant hydraulic fluid based on esters of phosphates. It belongs to the group known as HFD fluids ; its fire resistance is can be explained by its molecular structure.

Some elastic materials, particularly thermoplastics , become deformed in their cold (normal) state when under a load. This means elastic deformation and therefore elastic tension start to decline.

Total area of the filter element that is subjected to the flow rate. To make this area as large as possible with given filter dimensions, the majority of are folded.

Piston with piston rod on both sides, mostly of the same size. The term synchronizing cylinder is used.

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

With a digital measured signal the unlimited number of values of the measured variable faces the limited number of values of the measured signal . A value range for the measured variable is therefore

Term from circuit technology. If a valve in the bypass (secondary flow) is switched, then it opens a flow path for the flow rate bypassing the rest of the control arrangement.

Collective term for all measures, rules and laws required to construct a control . This applies both to controls in signalling and to controls in terms of power.

Collection of programs for constantly repeated operations (e.g. individual mathematical operations). The program library also contains all user-specific programs or those made available by the manufac

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).
