дренажен отвор

Explanation:
В хидравликата "дренажни" се наричат линиите (контурите, тръбопроводите), по които излишъкът от хидравлична течност изтича обратно към резервоара при налягане, близко до атмосферното.

Тук не става дума за обезвъздушаване (което е по-често срещаното значение на bleed), а за това:

bleed off or bleed down: reduce pressure by letting oil or gas escape at a low rate.
