What is the difference between hydraulic and pneumatic components
Driver medium is different, one for the hydraulic oil (liquid), is a compressed air (gas), the pressure is different also, this is how simple the precise control displacement, affirmation is hydraulic pressure, liquid incompressibility, can very good control of displacement
This very different hydraulic element is some hydraulic valve or hydraulic pump, hydraulic pressure is mainly the equipment is more!
It must be hydraulic pressure, you go to see hydraulic efficiency of the net hydraulic control of the inside of the clip of the egg that the inside of the egg is the video understand, very cow x, be in hydraulic efficiency net BBS
