Abstract

Aparato de bombeo de combustible para suministrar combustible a un motor de combustión interna, y de la clase que comprende una carcasa, un miembro distribuidor rotativo dentro de la carcasa, una bomba de inyección que incluye una parte rotativa que puede girar con el miembro distribuidor, un agujero formado en dicha parte rotativa, un émbolo de bombeo situado en dicho agujero, un anillo de leva situado en la carcasa, teniendo dicho anillo de leva lóbulos de leva espaciados que pueden impartir movimiento hacia el interior al émbolo cuando giran la parte rotativa y el miembro distribuidor, una pluralidad de orificios de salida formados en la carcasa y que, durante el uso, son conectados a las boquillas de inyección de combustible respectivamente de un motor asociado, un paso de entrega en el miembro distribuidor, comunicando dicho paso de entrega con dicho agujero y estando colocado para coincidir con los orificios de salida por turno durante periodos sucesivos de movimiento hacia el interior del émbolo, un medio suministrador de combustible en la carcasa y un miembro distribuidor a través del cual puede fluir el combustible a dicho agujero al menos durante parte del tiempo en que el paso de entrega no está en coincidencia con un orificio de salida, incluyendo dicho medio suministrador de combustible un paso de suministro en la carcasa, una fuente de combustible bajo presión para suministrar combustible a dicho paso de suministro, medios de mariposa para controlar el flujo del combustible a través de dicho paso de suministro y medios accionables en asociación con dicho medio de mariposa para permitir que el agujero sea ventilado a una baja presión cuando es regulado el medio de mariposa para impedir que fluya el combustible desde dicha fuente al agujero.
