Surface roughness (roughness depth) refers to the unevenness of actual surfaces based on the material involved and how is has been processed. Surface roughness is largely responsible for the wear experienced

mechanical (fluid) variable using appropriate measuring devices . However, it can also be determined based on algorithms from mathematical models. Another characteristic used to distinguish between feedbacks

with 1 or 2 piston rods. There are also numerous special forms. The load for a hydraulic cylinder is based on the respective load model . In terms of the design, a distinction is made between: standard cylinder

of pressure and fluid flow. The following are generally used as hydraulic fluids: Hydraulic fluids based on mineral oil Flame-resistant hydraulic fluids Readily biodegradable hydraulic fluids Hydraulics

shows the interaction of the functions better visually. The task formulation on which the diagram is based is the same as for the flow diagram and function diagram.

the various possibilities, four have become more widespread (Figure E 25) : Moving coil : Operates based on the electrodynamic principle. It combines low hysteresis and good linearity with very good dynamic

lines (ports) and with 2, 3, sometimes 4 switching positions . The directional valves are identified based on the number of usable connections and switching positions. Thus in hydraulics : 2/2-way directional

the mass flow and/or energy flow of the device to be controlled constantly within the design range based on an analogue input signal. A quasi-continuous final controlling device is present if not all, but

fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, " hydropneumatic accumulator ") and, more rarely, springs or weights

until the 1970s hydraulic components and systems were primarily developed by innovative engineers based on customer requirements and practical experience. Countless devices, parts for devices and technical
