Abstract

Perfeccionamientos en bombas inyectoras de combustible para motores de combustión interna, especialmente motores diesel, con un émbolo de bomba guiado móvil axialmente en rotación en un taladro de cilindro, que presenta una cara de mando delimitado por dos cantos de mando que presentan por lo menos un canto de mando inclinado, y que trabaja en cooperación con un orificio de mando de la pared del taladro de cilindro, y con una cámara de trabajo de bomba que como parte del taladro de cilindro está por una parte delimitada por una cara frontal del embolo y está por otra parte comunicada con una tubería de presión que va a la tobera de inyección gobernada por la presión del combustible y cerrable por una válvula de presión, la cual es comunicable, a través de un conducto de descarga que circunda a la válvula de presión y a la cámara de trabajo de la bomba y desemboca mediante un taladro de mando auxiliar en el taladro del cilindro, y de una ranura de mando que va unida a la cara demando del émbolo de la bomba, directamente con el orificio de mando y a través de éste con una cámara de presión más baja, preferentemente la cámara de aspiración de la bomba, caracterizados porque para la conclusión de la impulsión de combustible la cámara de trabajo de la bomba se comunica con el orificio de mando a través de un canal de comunicación que va a la ranura de mando en el émbolo de bomba, gobernándose por la cara de mando del émbolo de bomba, y porque para descargar la tubería de presión el taladro de mando auxiliar se abre aproximadamente al mismo tiempo que el orificio e mando, por la misma o una segunda cara de mando en el émbolo de bomba.
