Abstract

Dispositivo obturador tubular autobloqueable para cuerpo hueco de extremo libre cilíndrico, y destinado a ser sometido a una prueba de presión, caracterizado porque está consttuido por un fondo de grosor suficiente para soportar la presión bajo la cual el cuerpo debe ser probado, disminuido en la holgura necesaria para su ajuste en el citado cuerpo, prolongándose dicho fondo con un faldón cilíndrico del mismo diámetro, abierto en su otro extremo y susceptible de ensancharse bajo el efecto de la presión de prueba.
