Error that arises if continuously changing variables are measured by digital means because the measured values can only be measured at specific times due to the finite time required for the A/D conver

Semiconductor memory

Term used occasionally for 2-way plug-in valves.

Construction type of displacement pumps with multiple pistons, which, as in the radial piston pump, are arranged in a star shape around and perpendicular to the drive axis. They can be subjected to pr

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

Fire-resistant fluids based on "water in oil", i.e. an emulsion of around 40% water in mineral oil. Not used in Germany (although they are in the UK, for example).

Part with internal and external thread to connect two with different diameters.

When using flow dividers the division error of the smaller oil flow is multiplied by the indexing ratio, therefore in practical use, an indexing ratio of up to 4:1 is still reasonable.

The direction of rotation of a variable motor shaft can be changed, without changing the direction of the absorbed volume flow by moving the lifting element away from zero. Reversing motors are rarely

Interaction between mechanical actuations and hydraulic amplification (e.g. pump adjustment , copying system ).
