Abstract

Una bomba para la inyección de combustible en motores, que comprende un elemento estacionario y un elemento rotativo dispuesto en forma de distribuidos, llevando uno de estos elementos una leva y el otro pistones opuestos que son arrastrados por dicha leva, comprendiendo además esta bomba un canal de impulsión que comunica, durante los periodos de impulsión de los pistones opuestos, con los cilindros en que éstos se desplazan y con una de las salidas del distribuidor, caracterizada por un conducto de descarga susceptible de comunicar con el canal de impulsión durante dichos periodos, que es mandado por un pistón auxiliar o lanzadera que, durante la carrera de impulsión de los pistones opuestos, es arrastrado, para realizar su carrera de ida, por líquido impulsado por estos pistones, o incluso mejr por pistones auxiliares que funcionan en sincronismo con los pistones de la bomba y que, al final de su carrera de ida, abre el conducto de descarga, lo que provoca la parada de inyección de combustible en el motor, mientras que su carrera de retorno es asegurada por un resorte en el intervalo entre dos carreras de impulsión consecutivas de los pistones de la bomba, siendo frenada esta carrera de retorno porque la lanzadera, durante esta última carrera, debe hacer pasar, a través de una estrangulación de preferencia regulable, por lo menos una parte del líquido que anteriormente ha asegurado su carrera de ida.
