Abstract

Perfeccionamientos en dobles juntas tóricas, sensibles para obturadores, destinadas a contactar con un asiento de estanquidad con autocentrado sobre éste y que se monta en un alojamiento cuyo fondo está conformado de modo a podar cooperar con una junta de estructura clásica con vistas a obtener una estanquidad estática, caracterizados porque cada doble junta presenta, para la estanquidad con el fondo del alojamiento, una primera estructura de junta tórica que coopera con el fondo para obtener una estanquidad estática, para la estanquidad con el asiento de estanquidad que le está asociado, una segunda estructura de junta tórica retenida del lado opuesto al asiento de estanquidad, por un anillo de reacción, para la flexibilidad de este auto centrado, medios elásticos que actúan sobre la segunda estructura de junta, y para asegurar la continuidad de la estanquidad entre las estructuras de junta, una unión estanca y deformable.
