Abstract

Perfeccionamientos en inyectores de combustible para motores de combustión interna, destinados a mantener una relación de funcionamiento sincronizada con la cámara de combustión del motor de combustión interna en respuesta a una unidad electrónica de control, caracterizados porque se dota a cada inyector de un cuerpo que tiene un ánima central extendida axialmente, un núcleo móvil o pistón de bombeo primario y un núcleo móvil o pistón secundario, situados dentro del ánima para efectuar en la misma un movimiento axial, una tobera situada en el extremo del ánima central contrario al núcleo móvil o pistón de bombeo primario, una cámara de temporización o reglaje definida en el cuerpo entre el núcleo móvil o pistón de bombeo primario del núcleo móvil o pistón de bombeo secundario, una cámara de dosificación definida en el ánima entre el núcleo móvil secundario y. la tobera, pasos o conductos en el cuerpo del inyector para recibir combustible a presión y transmitir el combustible a la cámara detemporización o reglaje y la cámara de dosificación, y un dispositivo de válvula de regulación de funcionamiento electrónico situado intermedio a los pasos y conductos y la cámara de reglaje o temporización y destino a activarse de una forma selectiva por la unidad electrónica de control para regular el reglaje de. la descarga de combustible desde la cámara de dosificación a través de la tobera y para regular la cantidad de combustible descargada a través de la tobera y, para regular la cantidad de combustible almacenada en la cámara de dosificación después de la descarga de combustible.
