Abstract
Empaquetadura de estanqueidad hidráulica perfeccionada de un solo efecto, principalmente de estanqueidad dinámica o estática entre una guía do vástago y un vástago de émbolo montado de manera deslizante en dicha guita, que separa dos recintos, uno de los cuales esta bajo presión y el otro comunica con la atmósfera, del tipo de las que conjugan, en una realización anular monobloque, un elemento en forma de sombrerete o de copa y un núcleo blando que reparte la presión, caracterizada porque el elemento en forma de sombrero o de copa posee una sección asimétrica y presenta, donde contacta el vástago, un labio alargado protegido por el núcleo blando, el cual descompone la fuerza debida a la presión existente en uno de los dos recintos en un primer conjunto de fuerzas distribuidos sobre el contorno del labio de tal manera, que la longitud do contacto del labio aumenta automáticamente al incrementar la presión, y un segundo conjunto de fuerzas repartidas sobre la superficie cilíndrica de la garganta anular en la que se halla alojada la empaquetadura, mientras que detrás del citado labio, el elemento en forma de sombrerete o do copa posee una garganta que recibe un anillo guía y/o de antiextrusión.
