Abstract

Aparato de bombeo para la inyección de combustible que comprende una bomba de inyección accionable para suministrar combustible en relación cíclica con un motor al que es suministrado el combustible por el aparato, una bomba de alimentación para suministrar combustible bajo presión a la bomba de inyección, medios de válvula para controlar la presión de salida de la bomba de alimentación de tal modo que la misma varíe de acuerdo con la velocidad a la que es accionado el aparato, un medio de mariposa regulable por el operador para variar la cantidad de combustible suministrada a la bomba de inyección, una válvula dispuesta en el trayecto de flujo de combustible entre la bomba de alimentación y la bomba de inyección, incluyendo dicha válvula un elemento de válvula que es sometido a la presión de salida de la bomba de alimentación para empujar el miembro de válvula en una dirección apropiada para reducir el efecto de estrangulamiento de la válvula, medios sensibles durante su uso a la presión de aire suministrada al motor, un tope con el que coopera una parte conectada a dicho miembro de válvula, estando conformado dicho tope de manera que al producir se un incremento en la presión de aire suministrada al motor, el miembro de válvula se desplace para reducir el efecto de estrangulamiento de la válvula.
