Variable pump on which the geometric displacement can be set (limited) to a specific flow rate . This setting is made, e.g., by means of a stop screw that fixes the pivoting of the cylinder drum to a

Vessel for collecting and to some extent conditioning hydraulic fluid (removal of contamination and air, quietening). Is used at the same time to remove dissipated heat , however it is only suitable f

Losses in hydrostatic displacement machines are comprised of the leakage losses in the displacement elements and the control surfaces (summarised in the volumetric efficiency η Vol) and moment losses,

Hydraulic cylinders which have been designed for defined applications, where neither standard cylinders nor series-production cylinders can be used. This includes, for example, press cylinders or cyli

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
