Abstract
Un equipo hidraulico capaz de realizar una misma funcion como una bomba de desplazamiento variable al controlar dispositivos hidraulicos tales como valvulas de control en tal estado que una bomba hidraulicas accionada por una fuente de propulsion tal como una maquina termica o un motor se opera siempre con una alta eficiencia y a una velocidad generalmente constante sin importar el tipo de bomba, caracterizado en que se forma una fuente hidraulica de presion constante al accionar la bomba hidraulica mediante la fuente de propulsion que tiene, internamente o por adicion, una cantidad especifica de inercia, estando dispuestos los elementos perifericos de acuerdo con un requerimiento de carga, y las valvulas de control se abren y cierran de acuerdo con los estados de las cargas que incluyen un dispositivo de almacenamiento de energia o un motor hidraulico de manera que puede alimentarse a la carga el aceite a un flujo grande a baja presion.
