Abstract
Un sistema hidráulico perfeccionado con una bomba de transporte, una bomba de carga, cuya salida está unida con la entrada de la bomba de transporte a través de una tubería de impulsión, un motor hidráulico con una tubería de retorno que es cargado por la bomba de transporte, y una válvula que está conectada entre la tubería de retorno y un depósito colector y que está unida con la tubería de impulsión de tal manera que, para una presión predeterminada, la tubería de retorno está unida con la tubería de impulsión, caracterizado porque la válvula está unida con la salida de la bomba de carga y con el depósito colector de tal manera que la unión se lleva a cabo en función de la consecución de una presión predeterminada en la bomba de transporte.
