Abstract

Aparato de bombeo de inyección de combustible para suministrar combustible a un espacio de combustión de un motor de combustión interna y que comprende una boquilla de inyección colocada durante su uso sobre un motor de tal modo que el combustible suministrado a la boquilla sea inyectado dentro del espacio de combustión y una bomba de inyección para suministrar combustible a la boquilla en relación cíclica con el motor asociado, comprendiendo el aparato un cuerpo hueco alargado que lleva una boquilla de inyección en uno de sus extremos, medios que define un agujero en el cuerpo, un embolo que forma parte de dicha bomba deslizable en dicho agujero para variar el tamaño de una cámara de bombeo, medios elásticos para empujar el embolo en una dirección con vistas a incrementar el tamaño de la camara de bombeo, medios electromagnéticos accionables para mover el embolo contra la acción de dichos medios elásticos para desplazar el combustible desde la camara de bombeo a través de dicha boquilla, yuna entrada de combustible controlada por válvula para dicha camara de bombeo y a través de la cual puede fluir el combustible dentro de dicho agujero a partir de una fuente de combustible cuando es movido el embolo por dichos medios elásticos, actuando también dicha válvula para aliviar la presión en dicho agujero por su cooperación con el embolo, una vez que el émbolo ha sido movido a una posición predeterminada por los medios electromagnéticos.
