Pipe capacity
increased by the elasticity of the walls and any undissolved air in the oil. The equivalent bulk modulus K’ ( bulk modulus ) concerns these characteristics in respect of a pipe filled with oil. If the enclosed

Compression volume ΔVK
under pressure, Δ p = pressure increase in the space. In the typical pressure ranges up to 400 bar, V K becomes approximately 0.7 % of V o for each 100 bar. This means, for example, that if V o = 300 dm3

Inductive position measurement
to how far the plunger has been moved. In most cases, coils are operated at a carrier frequency of 5 kHz or higher. Following demodulation and filtering, a DC voltage signal will then be present. Thanks [...] output signal, a DC voltage signal will then be present. At high oscillator frequencies (50 to 500 kHz), it is possible to achieve highly dynamic measuring systems. Figure I 7: Inductive position measurement;
Hydraulic cylinder
this approach, a single cylinder is able to apply forces ranging from just a few N to up to 300,000 kN during strokes ranging from just a few cm to over 20 m. There are 3 basic designs available: single

Stiffness of actuators
additional factor – the influence of the ratio of the piston surface area to the annular area: with A K = piston surface area. Cylinders with a large active area and small stroke can be very stiff. In the
