French term or phrase: Orifice en appui
Hi again,


"La haute pression s’exerce sur la face arrière 230 du piston par l’intermédiaire de la rainure 70. La rainure 66 est à l’échappement par l’intermédiaire de la gorge annulaire et des perçages. La valve est maintenue en position arrière par la haute pression dans la rainure, avec l’orifice calibré en appui sur le siège."

Calibrated orifice…..
Your help is needed
Thank you

...orifice pressing against (the seat of the valve)
Explanation:
As I understand it, the valve is held in position by the presure but will/may open at a pressure depending on the diameter of the orifice (and possibly a spring?).

Maybe completely wrong, resulting from asker leaving out "calibré" from the requested term!
