The Oléohydraulique is a field of the Mécanique fluids bearing on the management of the Huile S moving.

Why oil is used as fluid transfer? With this question, the two principal answers are the following ones:

1. oil is an almost incompressible fluid and thus allows contrary to the pneumatic to transmit an effort in little time.

2. oil is a fluid viscous and thus makes it possible to lubricate the components (metal) such as the Pompe S, distributers, Vérin S and others.

There exist also the terms: Material hydraulic, transmissions hydrostatic, oleohydraulic, oleolic, hydraulic, hydrodynamic, hydraulic industrial, hydrodynamic, oleohydraulic, oleolic, hydraulic, transmissions hydrostatic, open circuits and closed

Hydraulic material it is the big family of industrial hydraulics (hydraulic presses for example), or machine rolling of public works (excavator for example

The topic hydrodynamic, oleohydraulic, oleolic, hydraulic are also one can used to treat topic of the hydraulic material which is the great credits in the directories professional

The hydraulic word is most common it comes owing to the fact that at the beginning one used water, then an emulsion oils and water which is used still a little, in particular because it is less enflammable which oil

The hydro prefix is often used for the name of the companies which deals with hydraulics www.HYDRO-TG.fr example

The hydrostatic transmissions is another term mainly used for the open circuits and closed, example pumps driven by the diesel engine, energy is transmitted by drain to the hydraulic engine which can be with several ten meters, to the end the hydraulic engine transmits a rotary energy, contrary to the jack which transmits an energy while pushing or drawing alternatively, then oil turns over to the pump and so on
