Abstract
Obturador para vástago de pistón de un cilindro hidráulico, del tipo formado de tres piezas que se fija en un saliente formado en la primera de dos estructuras cilíndricas coincidentes, en el cual ha de quedar contenido fluído a presión por delante del saliente, caracterizado porque cada obturador comprende: un anillo de cojinete indeformable continuo en el saliente con una primera superficie cilíndrica para hacer contacto con la superficie de la segunda de las estructuras cilíndricas y que tiene una segunda superficie cilíndrica de mayor profundidad de la superficie primera encarada en sentido contrario a la segunda de las estructuras cilíndricas y que tiene una superficie extrema cónica encarada hacia atrás; un anillo obturador de soporte indeformable contínuo que tiene una superficie extrema cónica encarada hacia adelante coincidente con la superficie extrema cónica encarada hacia atrás del anilllo de cojinete y un anillo resilente contínuo comprimible en el saliente en el lado del anillo de cojinete opuesto a la segunda estructura cilíndrica contrarrestando al anillo de cojinete y al anillo obturador.
