very expensive and only suitable for a few linking applications given that few hydraulic components can be miniaturised and the amount of assembly work involved. It is only used therefore in cases where

oil is lacking a series of characteristics for its tasks as a hydraulic fluid; these characteristics can be obtained by adding substances. These include substances for the improvement of the rust protection

Parameter for the power losses occurring in hydraulic systems, which can be noticed in the form of and leakage losses . There are also mechanical losses as a result of friction (Figure H 20) . A distinction

rate inside a pipe. It is based on the mass inertia associated with the fluid. The following equation can be written for the change in flow rate dQ/dt, based on a given pressure difference Δp: With a pipe

controlled subsystem it is straightforward to find a controller with which a stable control circuit can be assembled.
