I have a project that include having something like a syringe that will be filled with ink, I need a mechanism, part(equipment, or an idea to apply a pressure on the syringe automatically (electrical) not manually.
To make it Simple: the syringe need pressure and I need that pressure to be without human interference.
How about a simple servo?

I thought about it, but I the pressure movement is linear and the servo is rotational, unless you mean linear servo.
Stepper Motor Syringe pump.
Can be made easily with some aluminium bar + bearings + threaded rod and bits and bats.
Johnny010 thats a good idea, thanks
CrossRoads the image show pulling out which seems write but pushing in will I am not sure what is the thing that connect the servo with the syringe ?
What connects? That's up you. Flat piece of plastic, hole thru both ends, screw/nut to servo control horn, same to plunger handle somehow?

Do the math rotation - > linear. Code it and Suddenly, your thing is linear.
Probably need some trig things in there to do it. Sin, Cos..

Stepper motor and worm gear for precision
Well a 1/8th " threaded rod will move a nut 1/8th of an inch on a full turn...so yeah...not exactly the worlds most crazy maths.
No need for trig here.
