What is a check valve?
A check valve only allows fluid (gas or liquid) to flow freely in one direction (marked by arrow), whilst blocking it in the opposite direction. This valve does not seal perfectly, this is due to the tolerances achievable with 3d printing.
How does it work?
Inside the valve body there is a moveable plug (red) which is puschend by the fluid flow. Depending on the position the plug either blocks the flow path or opens ist.
