Abstract

Válvula de descarga para aparatos de bombeo de combustible líquido, siendo la válvula del género dispuesto en conjunto a la bomba de inyección de combustible y que se abre durante una carrera de inyección para permitir que circule o fluya combustible hacia el correspondiente motor térmico y que entonces se cierra y permite que una cantidad predeterminada de combustible refluya hacia la bomba el final de la carrera de inyección, caracterizada porque comprende, en combinación, un órgano deslizable, entre un par de topes, dentro de un orificio, constituyendo dicho orificio parte del paso de flujo de la bomba de inyección hacia el correspondiente motor térmico, y medios obturadores contenidos dentro del órgano y dispuestos para abrirse cuando el órgano ha sido movido en un grado predeterminado por el flujo de combustible durante una carrera de inyección hacia el primero de dichos topes, abriéndose dichos medios obturadores para permitir el flujo continuado de combustible durante la carrera de inyección pero cerrándose al final de la carrera de inyección, moviéndose entonces el órgano hacia el contacto con el segundo tope por lo que permite que refluya una cantidad predeterminada de combustible hacia la bomba de inyección.
