Abstract

La presente invención se refiere a mejoras en un dispositivo anular para evitar explosiones, que tiene una unidad obturadora que tiene un eje longitudinal, la unidad obturadora está adaptada para ser comprimida durante el avance axial de un pistón en un alojamiento, la unidad obturadora incluye insertos metálicos separados por lo general en forma circular alrededor del eje; los insertos tienen almas que se extienden generalmente en forma longitudinal y un conducto anular de material elastomérico que se extiende alrededor del eje y que incrusta las almas de manera que las almas anclen el material durante su desplazamiento; el conducto anular tiene un agujero, caracterizadas porque el conducto anular tiene una primera sección de cuerpo que es desplazada radialmente hacia adentro por el pistón durante su movimiento axial y una segunda sección de cuerpo que va a comprimirse axialmente mediante el pistón durante su avance de manera que la segunda sección de cuerpo acopla compresivamente la extensión de la superficie interna del alojamiento; la primera y la segunda secciones de cuerpo son integrales y están en alineamiento longitudinal antes de la compresión de la unidad obturadora por el pistón, y el pistón tiene una primera porción frustocónica de menor angularidad en relación con el eje y una segunda porción frustocónica de mayor angularidad con relación al eje; la segunda porción tiene una mayor separación radial del eje que la primera porción; las porciones están colocadas radialmente hacia afuera de las almas.
