Abstract

L'invention concerne une soupape à plaques segmentées (1) comprenant un carter de soupape (2), un disque fixe (8) agencé de manière solidaire en rotation sur le carter de soupape (2), un disque mobile (17) monté de manière à pouvoir tourner dans le carter de soupape (2) et un dispositif de déplacement (3) agencé sur le carter de soupape (2) et coopérant avec le disque mobile (17). Le disque mobile (17) repose à plat sur le disque fixe (8). Le disque mobile (17) et le disque fixe (8) comportent des orifices de passage (9, 18) adaptés les uns aux autres. Le disque mobile (17) peut être tourné dans une position ouverte et dans une position fermée. Les orifices de passage (9, 18) du disque mobile (17) et du disque fixe (8) sont adjacents les uns aux autres en position ouverte et forment des canaux de passage (19). Les orifices de passage du disque mobile (17) et du disque fixe (8) sont décalés les uns par rapport aux autres en position fermée. Le disque fixe (8) et le disque mobile (17) comportent chacun un alésage axial (10, 16). Un élément de palier est réalisé sur le disque fixe (8). Le disque mobile (17) est agencé de manière à pouvoir tourner sur l'élément de palier. L'invention concerne également un ensemble de turbines à vapeur comprenant une première turbine à vapeur et une deuxième turbine à vapeur, et un canal d'écoulement agencé entre la première turbine à vapeur et la deuxième turbine à vapeur. La première turbine à vapeur et la deuxième turbine à vapeur présentent un rotor commun. Une soupape à plaques segmentées (1) est agencée dans le canal d'écoulement. Le rotor est agencé dans l'alésage axial (10) du disque fixe (8).
