parameters. Performance maps may be represented as Dürer's shell curves (Figure K 8 a) or in three dimensions (b) . Figure K 8: Performance map as a Dürer's shell diagram (a) and in three dimensions (b)
Piston type accumulator
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 for diaphragm [...] points are the seal inside the piston and the weight of the piston in terms of fast removals.

Copying attachment
controls whereby the tool follows the instructions taken from a template (or a sample workpiece) ( Figure K 31 ). The core element of a copying attachment during mechanical sampling is the copying valve and during [...] spindle. With double-axis copying, both axis directions are actuated hydraulically (cross slides). Figure K 31: Copying attachment
Ball valve
Is available up to the largest nominal widths ( Figure K 39 ). Ball check valve : Check valve which uses a ball as the blocking element. Figure K 39: 2/2-way ball valve
Cavitation erosion
(Figure K 3) . The risk of cavitation erosion is much higher when water rather than mineral oils is used as the pressure fluid. Cavitation erosion is a form of particle jet erosion . Figure K 3: Cavitation
Cylinder
force F K is created by the influence of the pressure p of the transfer medium on the piston area A K (the most common form of a cylinder): With this approach, forces from just a few N up to 300,000 kN can
Energy content of hydraulic fluid
this process can be significant. Example: ΔV k = 1.0 L; p = 300 bar; compression energy: 15 · 103 Nm. If this 1 L flows away in 0.5 s, a power of approx. 30 kW is released. [...] compression energy . To generate the pressure p in a space V o a specific portion of the volume ΔV K must be added: (in a pump this process takes place continuously or at very short intervals in the individual
