Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE INYECCION DE COMBUSTIBLE PROVISTA DE UN PISTON DE INYECCION AJUSTABLE (10) PARA REGULAR EL INICIO DE LA INYECCION, EN LA QUE EL PISTON DE INYECCION AJUSTABLE (10) ESTA EXPUESTO, DURANTE EL FUNCIONAMIENTO, A MOMENTOS DE VAIVEN DEBIDO A SU ARTICULACION EXCENTRICA CON UNA PIEZA (3) DEL ACCIONAMIENTO POR LEVAS DE UNA BOMBA DE INYECCION DE COMBUSTIBLE DISEÑADA COMO BOMBA DE INYECCION DE DISTRIBUCION. ADEMAS, EL PISTON DE INYECCION AJUSTABLE (10) ESTA EXPUESTO A OTRAS FUERZAS QUE SE DERIVAN DE UN SUMINISTRO RADIAL DEL COMBUSTIBLE A PRESION (55) SOBRE LA CARA PRACTICAMENTE OPUESTA A LA ARTICULACION DEL PISTON DE INYECCION AJUSTABLE (10). ESTAS OTRAS FUERZAS, JUNTO CON LAS FUERZAS DE MOMENTOS DE VAIVEN, EJERCEN GRANDES FUERZAS UNILATERALES DE PRESION EN DIRECCION RADIAL SOBRE EL PISTON DE INYECCION AJUSTABLE. GRACIAS A LA CREACION DE UN SEGUNDO CAMPO DE PRESION (57), EL PISTON DE INYECCION AJUSTABLE (10) EXPERIMENTA UNA COMPENSACION DE LAS FUERZAS QUE ACTUAN SOBRE EL Y, POR TANTO, UNA DISMINUCION NOTABLE DE LA SOBRECARGA RADIAL.
