Abstract
Perfeccionamientos en bombas giratorias para fluidos, del tipo que comprenden medios de alojamiento que forman una cámara de bombeo en la que está dispuesto giratorio un elemento de bombeo que comporta un eje de giro, cavidades de fluido de expansión y cavidades de fluido de contracción, cuyos medios de alojamiento presenta, además, una lumbrera de admisión de fluido en comunicación con las cavidades de contracción, y una lumbrera de descarga para conexión a un aparato accionado por fluido, una trayectoria de fluido de descarga que establece comunicación entre la lumbrera de salida y la lumbrera de descarga medios que definen un depósito de fluido en comunicación abierta con la lumbrera de entrada y medios valvulares accionables para desviar el fluido en exceso desde la trayectoria de fluido de descarga el fluido en exceso desdela trayectoria de fluido de descarga a través de una lumbrera de derivación , caracterizados por comprender medios que definen una trayectoria de flujo de derivacióncon zona de flujo de sección transversal en general constante que comunica con el fluido en exceso procedente de dicha lumbrera de derivación, incluyendo dicha trayectoria de flujo de derivación una porción terminal dispuesta adyacente a dicha lumbrera de entrada y orientada en general axialmente para permitir que por lo menos una porción de dicho fluido en exceso fluya por dicha lumbrera de admisión.
