Abstract
UN OBTURADOR DE EJE.COMPRENDE UNA CAJA QUE CONTIENE UN ANILLO DE ESTANQUIDAD (20) CONSISTENTE EN UN MANGUITO (24) DE MATERIAL DE PLASTICO, POR EJEMPLO PTFE, Y UN ANILLO ELASTOMERO (30) RODEANDO AL MANGUITO. LAS DIMENSIONES DEL MANGUITO SON LAS NECESARIAS PARA QUE PUEDA ESCAPAR FLUIDO ENTRE EL MANGUITO Y EL EJE (10). SE APLICA PRESION DE UN FLUIDO AL ANILLO ELASTOMERO (24) PARA APLICAR UNA FUERZA RADIAL EN EL MANGUITO CON EL FIN DE REDUCIR LA FUGA DE FLUIDO A UN NIVEL ACEPTABLE, SI BIEN MANTENIENDO UNA PELICULA DE FLUIDO HIDRODINAMICAMENTE ESTABLE ENTRE EL MANGUITO Y EL EJE.
