Title
(EN) BONDED VALVE SEAT
(FR) SIÈGE DE SOUPAPE LIÉ
Abstract
(EN) A valve seat (100') includes a first end (110a), a second end (110b) positioned opposite from the first end, and a body (150) extending from the first end to the second end, the body defining an inner surface (152) and an outer surface (154), the inner surface defining a main bore (156) extending through the body from the first end to the second end, the main bore defining a main bore axis (101), the body defining a shaft bore (160a, b) extending from the inner surface to the outer surface, the shaft bore defining a shaft bore axis (161) positioned perpendicular to the main bore axis, the shaft bore defining an inner shaft opening (162a, b) and an outer shaft opening (164a, b), the body defining a concave seat bearing surface (169a, b) extending around the inner shaft opening.
(FR) Un siège de soupape (100') comporte une première extrémité (110a), une seconde extrémité (110b) positionnée à l'opposé de la première extrémité, et un corps (150) s'étendant de la première extrémité à la seconde extrémité, le corps définissant une surface interne (152) et une surface externe (154), la surface interne définissant un alésage principal (156) s'étendant à travers le corps de la première extrémité à la seconde extrémité, l'alésage principal définissant un axe d'alésage principal (101), le corps définissant un alésage d'arbre (160a,b) s'étendant de la surface interne à la surface externe, l'alésage d'arbre définissant un axe d'alésage d'arbre (161) positionné perpendiculairement à l'axe d'alésage principal, l'alésage d'arbre définissant une ouverture d'arbre interne (162a,b) et une ouverture d'arbre externe (164a,b), le corps définissant une surface d'appui de siège concave (169a,b) s'étendant autour de l'ouverture d'arbre interne.
