Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE ENGRANAJES INTERIORES SIN HOCES, CON UNA RUEDA HUECA INTERIOR DENTADA (6) Y UN PIÑON (5) ENGRANADO CON LA RUEDA HUECA (6), QUE ESTAN APOYADOS CONJUNTAMENTE DE FORMA GIRATORIA EN UNA CARCASA (1), CUYA EXTENSION AXIAL CORRESPONDE AL ANCHO DEL DENTADO (12) DE LA RUEDA HUECA (6) Y DEL PIÑON (5), Y LA CUAL PRESENTA UN EMPALME DE SUCCION (7) Y UN EMPALME DE PRESION (10), EN EL QUE LA RUEDA HUECA (6) PRESENTA RUPTURAS RADIALES (17) PARA EL MEDIO A BOMBEAR, Y POR LO QUE EN LAS CABEZAS DE LOS DIENTES (14) DE LA RUEDA HUECA (6) O EN LAS CABEZAS DE LOS DIENTES (13) DEL PIÑON (5) SE HA INCORPORADO EN CADA UNO DE ELLOS, UN ELEMENTO DE ESTANQUEIDAD (30) MOVIL RADIALMENTE EN LA CORRESPONDIENTE RANURA PERFILADA (34), QUE PUEDE DESLIZARSE EN LA CABEZA DEL DIENTE OPUESTA DEL ENGRANAJE (5) O DE LA RUEDA HUECA (6). LA INVENCION SE CARACTERIZA, PORQUE EL ELEMENTO DE ESTANQUEIDAD (30) ESTA DIMENSIONADO EN LA ZONA DE DESLIZAMIENTO DE TAL FORMA, QUE ACAPARA LA SUPERFICIE TOTAL DE LA CABEZA DE LA RUEDA HUECA O DE LA CABEZA DEL PIÑON.
