intake valve
Engine breathing port
An intake valve is a one-way valve that allows fluid or gas to enter a chamber while preventing backflow.
In internal combustion engines, the intake valve opens to let the air-fuel mixture into the cylinder during the intake stroke, then closes during compression and combustion.
The term applies similarly to pumps, compressors, and other mechanical systems where controlled entry of substances is essential.
