Abstract

Agencement de soupape, comprenant une soupape dont la tête présente une surface d'obturation munie d'un blindage et une cloche de soupape en acier coulé munie d'un guide de soupape, d'une chambre annulaire supérieure à fluide refroidisseur et d'une chambre annulaire inférieure à fluide refroidisseur communiquant avec la précédente par des canaux de liaison et formée par soudage d'une bague de siège à la cloche de soupape. La bague de siège 9 est formée d'une pièce en acier coulé, la bague de siège 9 aussi bien que la surface d'obturation de la tête de soupape 4 présentent un blindage 10, il et la dureté du blindage 10 de la bague de siège 9 est choisie inférieure à celle du blindage 11 de la tête de soupape 4. Application aux moteurs Diesel de grande puissance.A valve arrangement, comprising a valve with a head having a shielded sealing surface and a cast steel valve bell with a valve guide, an upper annular coolant chamber, and a valve housing. lower annular coolant chamber communicating with the previous one by connecting channels and formed by welding a seat ring to the valve bell. The seat ring 9 is formed from a piece of cast steel, the seat ring 9 as well as the sealing surface of the valve head 4 have a shield 10, it and the hardness of the shield 10 of the pressure ring. seat 9 is chosen lower than that of the shield 11 of the valve head 4. Application to high power diesel engines.
