Abstract

INSTALACION OBTURADORA PARA EL ESTANCAMIENTO DE UN VASTAGO DE EMBOLO (14) ESPECIALMENTE DE UN VASTAGO DE EMBOLO DE UN RESORTE DE GAS (10), QUE MUESTRA UN RECIPIENTE (11), DONDE SE ENCUENTRA GAS, QUE ESTA BAJO PRESION. EL VASTAGO DE EMBOLO SE CONDUCE SOBRE EL FINAL, LATERAL A LA SALIDA, DEL RECIPIENTE MEDIANTE UNA DIRECCION DEL VASTAGO DE EMBOLO (18) Y ES ESTANQUEIZADO PARA FUERA A TRAVES DE UNA JUNTA DEL VASTADO DE EMBOLO (17). ENTRE LA JUNTA DEL VASTAFO DE EMBOLO Y EL ESPACIO DE TRABAJO (12), QUE CONTIENE EL GAS A PRESION SE ENCUENTRA UNA CAMARA DE LIQUIDOS (13) LLENADA CON UN COLECTOR DE LIQUIDOS, QUE ESTA SEPARADO DEL ESPACIO DE TRABAJO LLENADO CON UN ANILLO OBTURADOR. EL ANILLO OBTURADOR (15) ESTA EQUIPADO SOBRE SU CONTORNO EXTERIOR (19) CON REBORDES OBTURADORES (20) Y ESTA SITUADO SOBRE LA PARED INTERIOR (30) DEL TUBO DEL RECIPIENTE (11). POR DENTRO ESTA FORMADO RADIALMENTE COMO UNA FALDA DE OBTURACION (22) ESTRECHA, QUE SE SITUA SOBRE LA SUPERFICIE SUPERIOR (14A) DEL VASTAGO DE EMBOLO (14).
