Abstract
EN CONEXION CON UNA BOMBA DE RUEDA DENTADA INTERIOR CON RUEDA (6) HUECA DENTADA INTERIORMENTE Y CON UN PIÑON (5) QUE ENGRANA EN LA RUEDA (6) HUECA, LA RUEDA (6) HUECA MUESTRA ROTURAS (17) RADIALES PARA EL MEDIO A SER BOMBEADO. EN LOS CABEZALES (14) DENTADOS DE LA RUEDA (6) HUECA O EN LOS CABEZALES (13) DENTADOS DEL PIÑON (5) RESPECTIVAMENTE SE UTILIZA UN ELEMENTO (30) DE ESTANQUEIDAD MOVIL RADIALMENTE DE FORMA CORRESPONDIENTE A LA RANURA (4) DE PERFIL CONFIGURADA, QUE PUEDE DESLIZARSE EN EL CABEZAL DENTADO OPUESTO DEL PIÑON (5) O DE LA RUEDA (6) HUECA. SE PROPONE QUE LA FORMA DE CABEZAL DEL ELEMENTO (30) DE ESTANQUEIDAD Y LA FORMA DEL PIE DEL HUECO DE DIENTE DE LA RUEDA (6) HUECA O DEL PIÑON (5) ESTEN DISPUESTOS EN UNA COINCIDENCIA DE UNO SOBRE OTRO DE TAL MODO, QUE EN LA ZONA DEL PUNTO MUERTO SE VERIFIQUE LA ESTANQUEIDAD ENTRE EL ESPACIO DE PRESION Y EL ESPACIO DE ASPIRACION DEL ELEMENTO (30) DE ESTANQUEIDAD.
