Abstract

L'invention a trait à des surfaces (16, 20) annulaires d'obturation d'un corps de soupape (10) et de l'obturateur (12) associé, constituées par une zone de cercles produits par l'intersection de la surface réglée d'un cône (K) doté d'une base elliptique et de plans parallèles l'un par rapport à l'autre, perpendiculaires à un axe (A1) longitudinal de la vanne. Ladite invention a également trait à un procédé et à une machine-outil permettant de produire ces surfaces (16, 20) annulaires d'obturation.
