Abstract

Aparato de bombeo de combustible que comprende un alojamiento provisto de un taladro cilíndrico, un miembro distribuidor dispuesto en el taladro cilíndrico y rotatorio respecto al alojamiento, presentando este miembro distribuidor un taladro extendido transversalmente respecto al eje de rotación de tal miembro, un émbolo situado en el taladro transversal y accionable hacia el interior mediante lóbulos de leva formados en la periferia interna de una anilla de leva situada dentro del alojamiento, un estribo desplazable con el émbolo, por lo menos una anilla de tope a la que es acoplable el estribo para limitar el movimiento del respectivo émbolo hacia fuera, incluyendo la anilla de tope o cada una de ellas una serie de porciones, cada una de las cuales presenta una superficie arqueada a la que es acoplable el estribo o cada uno de ellos para limitar el movimiento del respectivo émbolo hacia fuera, estando centrada cada superficie arqueada generalmente sobre el eje de rotación del miembro distribuidor y siendo desplazables dichas porciones en sentido sustancialmente radial hacia el interior y exterior.
