Abstract

BOMBA GERROTOR MOSTRADA EN LA FIGURA 4 QUE TIENE PASOS 32 EXTENDIENDOSE PARALELAMENTE AL EJE DE ROTACION A TRAVES DEL ANILLO LOBULAR HEMBRA, Y PASOS SIMILARES (NO MOSTRADOS EN EL DIBUJO) A TRAVES DEL ROTOR LOBULAR MACHO. ESTOS, O CUALQUIERA DE ELLOS, COMO LOS 42A , PERMITEN PASAR EL FLUJO DESDE LA ENTRADA 38 A UNA CAMARA DE TRABAJO YA DIRECTAMENTE EN EL EXTREMO DE ENTRADA, O DESPUES DEL FLUJO A TRAVES DE ESOS PASOS Y A TRAVES DEL PASO DE TRASLADO 43 EN EL EXTREMO AXIAL OPUESTO A LA ENTRADA, SIN REQUERIR UN PASO DE TRASLADO EXTERNAMENTE AL ANILLO. EL RESULTADO ES UN LLENADO AXIAL MEJOR DE LAS CAMARAS DE TRABAJO, EN UN DISEÑO PARTICULARMENTE COMPACTO.
