Cylindrical air pump (Cylinder and piston)
Cylindrical air pump (Cylinder and piston)
(OP)
Hi everybody,
Firstly, a bit about what I’m trying to do.
I need to upgrade a simple pump mechanism to something more industrial and durable.
The mechanism is basically a servo, rack & pinion driven (2.5mL) syringe. The purpose of this mechanism is to periodically push a small amount of air through a system of air lines.
I want to keep this general concept, and was wondering if there are air cylinders that work like an air pump (same as bicycle pumps), where they draw in external air and push it forward.
I did try to search google for something like that, but with no luck as I found only pneumatic cylinders and I’m not sure if they meant to work as air pumps, and I prefer a product that is meant to works as a pump rather than repurposing something.
I’m pretty sure that there are components that will answer my need, as at my lab we have a couple of ventilators that work on the same principle, what I’m not so sure about, if those cylinders (in the ventilators) are designed specifically for those machines (in term of operation and not design).

Is this air at very low pressure? You state a volume, but not a pressure.
Also how often?
Could you use a controlled lightly pressurised supply and simply pulse a solenoid valve? you might need to do a bit of trial and error to fix a pulse duration but if you use a really small tube then 2.5ml should be easy to set up.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
