Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE DESPLAZAMIENTO, POR EJEMPLO BOMBA DE CELDAS DE ALETAS, CON UNA VALVULA (13) DE REGULACION DE FLUJO SOBRE EL PISTON (22) DE REGULACION, DONDE POR UN LADO ACTUA LA PRESION DE LA BOMBA Y POR OTRO LADO LA PRESION DEL CONSUMIDOR TOMADA A TRAVES DE UN DISPOSITIVO DE ESTRANGULACION. EL EMBOLO (22) DE REGULACION ACTUA COMO UNA ESCALA A PRESION DONDE LA DIFERENCIA DE PRESION CUANDO AUMENTA LA VELOCIDAD DE LA BOMBA ACTUA COMO UNA MEDIDA PARA LA CANTIDAD REGULADA TRANSPORTADA. EL DISPOSITIVO DE ESTRANGULACION PARA APLICACION DE LA DIFERENCIA DE PRESION CONTIENE UN EMBOLO (17) DE ESTRANGULACION MOVIL CONTRA LA FUERZA DE UN RESORTE (16) EN UNA PERFORACION (15) DE EMBOLO, QUE CIERRA UNA ABERTURA (14) SOBRE EL LADO DE PRESION EN UN DISCO (7) DE CONTROL EN LA POSICION BASICA. DE ACUERDO CON LA INVENCION LA PERFORACION (15) DE EMBOLO DISPONE DE UN CANAL (18) BY-PASS QUE CONECTA DE FORMA CONTINUA LA BOMBA CON CAMARA (15A) DE RESORTE EN EL EMBOLO (17) DE ESTRANGULACION.ADICIONALMENTE DEPENDIENDO DE LA CUOTA DE FLUJO, EL PISTON DE ESTRANGULACION REGULA LA SECCION TRANSVERSAL DE UN CANAL (20) DE ESTRANGULACION PROVISTO CON UNA CONEXION ENTRE LA CAMARA (15A) DE RESORTE Y EL CANAL (21) DE SALIDA. LA DISPOSICION TIENE LA VENTAJA DE QUE LA PRESION DIFERENCIAL DEL EMBOLO (22) DE REGULACION NO AFECTA EL EMBOLO (17) DE ESTRANGULACION DEL DISPOSITIVO ESTRANGULADOR. DADO QUE LA FUERZA DE RESORTE QUE ACTUA SOBRE EL EMBOLO (17) DE ESTRANGULACION PUEDE SER REDUCIDA, SE AHORRA POTENCIA.
