Abstract

Perfeccionamientos en las bombas de inyección de combustible, del tipo de distribuidor para motores de cilindros múltiples, combustión interna e ignición por comprensión, del tipo que comprende un cuerpo de bomba con una cavidad cilíndrica interna y una cámara de compresión; -medios para la introducción de combustible en dicha camara de compresión; -medios de pistón deslizables en el interior del cuerpo para comprimir combustible en dicha camara de compresión;- una serie de aberturas de suministro en la pared de la cavidad cilíndrica del cuerpo para comunicación con cada uno de los cilindros del motor; -un miembro distribuidor giratorio dispuesto en dicha cavidad cilíndrica, girando dicho miembro distribuidor con el empleo de la bomba para efectuar una revolución completa en dicha cavidad en cada ciclo del motor; -dos medios de paso de combustible distintos, formados en dicho miembro de distribuidor giratorio y presentando cada uno un extremo de entrada permanentemente en comunicación con la cámara de compresión y un extremo de salida en la superficie externa del miembro distribuidor, situandose los extractos de salida de dichos pasos en dos áreas angularmente separadas entre sí de modo que entran intermitente en comunicación, al girar el miembro distribuidor, con sucesivas aberturas de suministro citadas para efectuar, en correspondencia con cada carrera de subministro de combustible de dichos medios de pistón, dos inyecciones de combustible en dos cilindros distintos del motor, con lo que la bomba suministran principal de combustible sustancialmente al final de la carrera de compresión, precedida de una pre-inyección de combustible, y -medios sensibles a la velocidad de giro del motor para controlar el tiempo de la inyección y aptos para adelantar el inicio de la carrera de suministro de los medios de pistón al aumentar la velocidad de giro del motor: caracterizada porque el ángulo (alfa) entre los extremos de salida de dichos dos medios dos medios de paso de combustible (11, 12) se determina de modo que cuando varia la velocidad de giro del motor los citados medios que contralar el tiempo de inyección producen una variación, según una regla predeterminada que depende de las característica del motor que se ha de alimentar con la bomba, en la realización de la cantidad de combustible pre-inyectado en cada cilindro en cada ciclo del motor frente a la cantidad de combustible inyectado en la inyección principal.
