Abstract

SE TRATA DE UNA BOMBA DE INYECCION DE COMBUSTIBLE PARA MAQUINAS MOTRICES DE COMBUSTION INTERNA SOBRECARGADAS CUYO ELEMENTO DE AJUSTE DE CANTIDAD (11) DISPONE DE UNA PALANCA DE CAMBIO (42) COMO LIMITADOR DE RECORRIDO, EN LA CUAL SE ALOJA UNA PALANCA GIRATORIA (51) QUE, POR SU PARTE, APOYA UN DISCO DE LEVA CON DOS LEVAS (17). EN EL SECTOR CURVADO (67) DE ESTE DISCO SE APOYA EL ELEMENTO DE AJUSTE DE CANTIDAD (11), SIEMPRE QUE HAY PLENA CARGA. LA DEFORMACION DE UNA MEMBRANA (23), QUE VARIA SEGUN LA PRESION DEL AIRE DE CARGA, SE TRANSMITE A TRAVES DE UNA VARA ELEVADORA (34) QUE MANEJA LA PALANCA (38) DE UN ELEMENTO INTERMEDIO GIRATORIO (37), A ESTE ELEMENTO (37) DONDE QUEDA TRANSFORMADO EN UN MOVIMIENTO DE GIRO. DEL ELEMENTO INTERMEDIO (37) SALE EN DIRECCION EXCENTRICA A SU EJE DE GIRO (54) Y HACIA LA PALANCA GIRATORIA (51), UN PERNO (56) EN EL QUE LA PALANCA GIRATORIA (51) SE APOYA EN REGIMEN DE PLENA CARGA. LA POSICION DE GIRO DEL DISCO DE LEVAS (17) SE MANEJA MEDIANTE UNA ESPIGA (68) DIRIGIDAPOR UN EMBOLO DE AJUSTE (73) DESPLAZABLE CONTRA LA FUERZA DE UN CONTRARRESORTE (82), QUE ES ACCIONADO POR LA PRESION QUE SEGUN EL REGIMEN DE REVOLUCIONES SE PRODUCE EN EL INTERIOR (10) DE LA BOMBA DE INYECCION Y SE ENCUENTRA ALOJADO EN UN CILINDRO (72) SITUADO DENTRO DE UNA VAINA (71) COAXIAL A LA ESPIGA (68). UN CAMBIO DE POSICION DE LA PALANCA MEDIANTE UN MOVIMIENTO GIRATORIO (51) PROVOCADO POR LA PRESION DEL AIRE DE CARGA Y UN CAMBIO DE POSICION DEL DISCO DE LEVAS (17) DENTRO DE LA PALANCA GIRATORIA (51), PROVOCADO POR UN CAMBIO EN EL REGIMEN DE REVOLUCIONES, PUEDEN SUCEDER SUCESIVA O SIMULTANEAMENTE.THIS IS A FUEL INJECTION PUMP FOR OVERLOADED INTERNAL COMBUSTION ENGINE MACHINES WHOSE QUANTITY ADJUSTMENT ELEMENT (11) HAS A CHANGE LEVER (42), WHICH IS A ROTATING LEVER (51) THAT, FOR ITS PART, SUPPORTS A CAM DISC WITH TWO CAMS (17). IN THE CURVED SECTOR (67) OF THIS DISC, THE QUANTITY ADJUSTMENT ELEMENT (11) IS SUPPORTED, WHETHER THERE IS A FULL LOAD. THE DEFORMATION OF A MEMBRANE (23), WHICH VARY ACCORDING TO THE PRESSURE OF THE CARGO AIR, IS TRANSMITTED THROUGH A LIFTING ROD (34) THAT HANDLES THE LEVER (38) OF A ROTATING INTERMEDIATE ELEMENT (37), TO THIS ELEMENT ( 37) WHERE IT IS TRANSFORMED INTO A TURN MOVEMENT. FROM THE INTERMEDIATE ELEMENT (37) IT EXITS IN AN ECCENTRIC DIRECTION TO ITS ROTATING AXIS (54) AND TOWARDS THE ROTATING LEVER (51), A BOLT (56) ON WHICH THE ROTATING LEVER (51) IS SUPPORTED IN A FULL LOAD REGIME. THE TURN POSITION OF THE CAM DISC (17) IS HANDLED THROUGH A TONGUE (68) DIRECTED BY AN ADJUSTMENT PIT (73) MOVABLE AGAINST THE FORCE OF A COUNTER-SPRING (82), WHICH IS ACTUATED BY THE PRESSURE ACCORDING TO THE REVOLUTION REGIME IT IS PRODUCED INSIDE (10) OF THE INJECTION PUMP AND IT IS FOUND IN A CYLINDER (72) LOCATED WITHIN A SHEATH (71) COAXIAL TO THE TONGUE (68). A CHANGE OF POSITION OF THE LEVER THROUGH A ROTATING MOVEMENT (51) CAUSED BY THE PRESSURE OF THE LOADING AIR AND A CHANGE OF POSITION OF THE CAM DISC (17), CAUSED BY A CHANGE IN THE REGIME OF REVOLUTIONS, THEY MAY HAPPEN SUCCESSIVE OR SIMULTANEOUSLY.
