Abstract

Llave de paso de membrana, del tipo que comprende un conducto o paso de fluído que incorpora un asiento de apoyo de una membrana de material elásticamente deformable apropiada para quedar apoyada sobre el citado asiento para obturar el conducto en la condición de cierre de la llave y para ser apartada del mismo en la condición de abertura de la llave de paso, estando conformada esta membrana. de modo que presenta una deformación sin compresión cuando está aplicada sobre el asiento, caracterizada porque la citada membrana (4), presenta unos pasos de fluído (7) apropiados para ser cerrados progresivamente cuando la membrana sufre la citada deformación sin compresión.
