Abstract

BOMBA DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA CON UN PISTON DE AJUSTE (11) PARA AJUSTAR EL MOMENTO DE LA INYECCION, QUE DELIMITA UNA CAMARA DE TRABAJO (14) EN UN CILINDRO (12). EN UN TALADRO CIEGO (17) EN EL PISTON DE AJUSTE (11) ESTA DISPUESTA DESPLAZABLE UNA CORREDERA DE CONTROL (18) IMPULSABLE POR UNA PRESION DE ALIMENTACION, QUE DELIMITA UNA CAMARA DE PRESION (21) EN EL TALADRO CIEGO (17). SEGUN LA POSICION DE LA CORREDERA DE CONTROL (18), LA CAMARA DE TRABAJO (14) SE CONECTA CON LA CAMARA DE PRESION (21) O CON UNA CAMARA DE DESCARGA (15). LA PRESION DE ABASTECIMIENTO SE GENERA POR MEDIO DE UNA BOMBA DE TRANSPORTE (33) Y SE MODIFICA POR MEDIO DE UNA VALVULA MAGNETICA (46) DISPUESTA EN LA LINEA DE SALIDA (44) EN FUNCION DE PARAMETROS DE FUNCIONAMIENTO DEL MOTOR DE COMBUSTION INTERNA, DE MANERA QUE SE REALIZA UN AJUSTE DEL MOMENTO DE LA INYECCION EN FUNCION DE LOS PARAMETROS DE FUNCIONAMIENTO.FUEL INJECTION PUMP FOR INTERNAL COMBUSTION ENGINES WITH AN ADJUSTMENT PISTON (11) TO ADJUST THE TIMING OF THE INJECTION, WHICH LIMITS A WORKING CHAMBER (14) IN A CYLINDER (12). IN A BLIND DRILL (17) IN THE ADJUSTMENT PISTON (11) A CONTROL SLIDE (18) PROPELLABLE BY A FEED PRESSURE, THAT DELIMINATES A PRESSURE CHAMBER (21) IN THE BLIND DRILL (17), IS DISPLACABLE. ACCORDING TO THE POSITION OF THE CONTROL SLIDE (18), THE WORKING CHAMBER (14) IS CONNECTED WITH THE PRESSURE CHAMBER (21) OR WITH A DISCHARGE CHAMBER (15). THE SUPPLY PRESSURE IS GENERATED THROUGH A TRANSPORT PUMP (33) AND IS MODIFIED THROUGH A MAGNETIC VALVE (46) ARRANGED AT THE OUTLET LINE (44) IN FUNCTION OF PARAMETERS OF OPERATION OF THE INTERNAL COMBUSTION ENGINE, HOW TO ADJUST THE TIMING OF THE INJECTION AS A FUNCTION OF THE OPERATION PARAMETERS.
