| description | A valve seat insert (38) for a gas exchange valve (24) controlling gas exchange of a cylinder (16) includes an insert body (40) having an inner peripheral surface (52), an outer peripheral surface (56), and a valve seating surface (59) structured to contact the gas exchange valve (24) at a closed position and profiled to limit valve recession thereof. The valve seating surface (59) includes an arrangement of linear segments and curved segments forming crowns (64) to contact the gas exchange valve (24) at different wear states.
Cette invention concerne une pièce rapportée de siège de soupape (38) pour une soupape d'échange gazeux (24) commandant l'échange gazeux d'un cylindre (16), comprenant un corps de pièce rapportée (40) ayant une surface périphérique interne (52), une surface périphérique externe (56), et une surface de siège de soupape (59) structurée pour entrer en contact avec la soupape d'échange gazeux (24) dans une position fermée et profilée pour limiter le renfoncement de soupape de celle-ci. La surface de siège de soupape (59) comprend un agencement de segments linéaires et de segments incurvés formant des bombages (64) pour entrer en contact avec la soupape d'échange gazeux (24) à différents états d'usure. |
