A check valve is a no return valve. That means a fluid flowing through it in one direction flows well, but it doesn’t flow in the other direction. Check valves are parts of several household items. They are also used widely in many many places in the industry. Cranes, pumps, and even your heart couldn’t work without a check valve.
All check valves have a moving part called the obturator which closes the valve when there’s a flowing in the reverse direction. Or that is what most people think. But there’s a check valve that Tesla patented which had no moving parts.
Agreed, it is not the best of check valves and has also has turbulence issues which is not good for any hydraulic system. But it sure is an awesome idea.
