Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE CONTROL PARA UNA BOMBA DE AJUSTE DE GRADO DE LLENADO CON AL MENOS UNA CAMARA DE DESPLAZAMIENTO QUE OPERA SEGUN EL PRINCIPIO DE ESTRANGULACION DE SUCCION, CON REGULACION CONTROLADA DEL VOLUMEN DE LAS CAMARAS DE DESPLAZAMIENTO Y DIRIGIDA PARA SU UTILIZACION ESPECIALMENTE EN SISTEMAS DE INYECCION DIESEL DE RAIL COMUN, ENTRE OTROS. FACILITA UN CONTROL PRECISO Y ALTAMENTE DINAMICO DE LA BOMBA DE AJUSTE DE GRADO DE LLENADO CON COSTE PEQUEÑO Y SIN LOS EFECTOS ADVERSOS SOBRE EL SISTEMA DE CAVITACION NO DESEADA. SOBRE EL LADO DE VACIO DE LA BOMBA SE DISPONE AL MENOS UNA VALVULA (21,21A,21B;134; 51,53,54;81;103) DE ESTRANGULACION DE 2/2 VIAS OPERADA MEDIANTE PRESION DIFERENCIAL. LA VALVULA DE 2/2 VIAS DE ESTE TIPO O DE BOMBA COMPLETA PUEDE SER APLICADA A UN GRUPO DE CAMARAS DE DESPLAZAMIENTO, O ALTERNATIVAMENTE, UNA VALVULA DE ESTE TIPO PUEDE SER COLOCADA ANTES DE CADA CAMARA DE DESPLAZAMIENTO INDIVIDUAL. EL CONTROL DE PRESION DIFERENCIAL DE CADA UNA DE LASVALVULAS DE 2/2 VIAS SE ACEPTA POR MEDIO DE UN DISPOSITIVO (27,150) DE AJUSTE SITUADO SOBRE EL LADO DE ALIMENTACION DE LA VALVULA DE 2/2 VIAS Y DISEÑADA COMO UNA VALVULA DE ESTRANGULACION O UNA VALVULA DE REGULACION DE FLUJO.
