Abstract

Un ensamble de bomba de chorro de conformidad con una modalidad ejemplificativa de la presente invención incluye un cuerpo de entrada arreglado en proximidad con una estructura de garganta para así, proporcionar una entrada entre el extremo de descarga del cuerpo de entrada y una estructura de garganta. Un flujo impulsor de un fluido motriz se suministra a una primera velocidad al cuerpo de entrada y se descarga a través de por lo menos una boquilla a una segunda velocidad más alta, lo cual crea una caída de presión en la estructura de garganta. La caída de presión facilita el primer flujo de succión introducido dentro de la entrada y un segundo flujo de succión introducido a través del por lo menos un canal que pasa a través del cuerpo de entrada. El por lo menos un canal está configurado de modo que el segundo flujo introducido queda aislado del flujo impulsor mientras pasa a través del cuerpo de entrada.
