Abstract

Una valvula de rotor (10) que tiene un sello de rotor (34) conteniendo una abertura (52) centralmente dispuesta para dirigir una presion externa (Pe) hacia una superficie trasera (35) del sello para aplicar una fuerza selladora contra una superficie selladora (36). Una proyeccion (38) del sello, que rodea la abertura, esta dispuesta dentro de un agujero (40) formado en un rotor (14) de la valvula. Un sello de anillo con forma de O (44) define la porcion de la superficie trasera expuesta a la presion externa. El rotor puede ser soportado sobre un extremo a traves de un ensamble de cojinete (80) y puede ser abierto en el extremo opuesto para recibir el agua de entrada. Los obturadores de superficie deslizante circunferencialmente distribuidos se extienden radialmente mas alla del diametro del rotor para soportar al rotor a lo largo de una superficie interior (39) del cuerpo de valvula (12).
