Abstract

LA BOMBA CONSTA DE UN CUERPO FORMADO POR DOS ELEMENTOS (2,3) UNIDOS ENTRE SI HERMETICAMENTE, ENTRE LOS CUALES SE DEFINE UNA CAMARA CENTRAL (5) EN LA QUE UN EJE MOTOR (6) LLEVA UNA EXCENTRICA (7) MONTADA DE FORMA GIRATORIA. VARIOS CILINDROS (9) QUE SE ABREN EN LA CAMARA CENTRAL (5) DEL CUERPO (2,3), Y DISPUESTOS RADIALMENTE ALREDEDOR DEL EJE (6), SE ENCUENTRAN ONTADOS EN UN ELEMENTO (2) DEL CUERPO (2,3) Y UNOS PISTONES (13) QUE COOPERAN CON LA EXCENTRICA (7) ESTAN ASIMISMO MONTADOS EN AQUEL DE FORMA DESLIZANTE. ESTOS CILINDROS ESTAN EN COMUNICACION CON UNA CAMARA DE SUMINISTRO (18) DEFINIDA EN EL CUERPO (2,3) ENTRE EL PRIMER Y EL SEGUNDO ELEMENTOS (2,3). LA CAMARA DE SUMINISTRO (18) ES DE CONFORMACION ANULAR Y SE ENCUENTRA EN POSICION RADIAL FUERA DE LA CAMARA CENTRAL (5). AL MENOS UN ELEMENTO DE SELLADO (31) PARA SEPARAR LA CAMARA DE SUMINISTRO (18) DE LA CENTRAL (5) SE HALLA INTERPUESTO ENTRE EL PRIMER Y EL SEGUNDO ELEMENTOS (2,3) DEL CUERPO. EXISTE AL MENOS UN PASO (50) FORMADO EN UNO (3) DE LOS ELEMENTOS (2,3) DEL CUERPO PARA PONER EN COMUNICACION A LA CAMARA DE SUMINISTRO (18) CON LA CAMARA CENTRAL (5). EN DICHO PASO (50) ESTA SITUADO UN DISPOSITIVO (51) CONTROLADO ELECTRICAMENTE Y ADAPTADO PARA CONTROLAR EL FLUJO DE FLUIDO QUE PASA A TRAVES DEL PASO (50) DE FORMA PREDETERMINADA.
