Abstract

Un sistema de bombas incluye un circuito de fluido de ciclo cerrado y un circuito de fluido de ciclo abierto. El circuito de fluido de ciclo cerrado incluye un motor para girar un primer componente conectado al circuito de fluido de ciclo cerrado. Una bomba de ciclo cerrado impulsa al motor a la alza a una primera velocidad de rotación máxima. El circuito de fluido de ciclo abierto incluye una bomba de ciclo abierto para impulsar un segundo componente conectado al circuito de fluido de ciclo abierto. Un circuito de control incluye una válvula de control para conmutar el flujo de salida a partir de la bomba de ciclo abierto. La válvula de control selectivamente conecta a la bomba de ciclo abierto con el circuito de fluido de ciclo cerrado y simultáneamente desconecta la bomba de ciclo abierto del circuito de fluido de ciclo abierto. Cuando la bomba de ciclo abierto se conecta al circuito de ciclo cerrado, la bomba de ciclo cerrado y la bomba de ciclo abierto impulsan al motor a una segunda velocidad de rotación mayor que la primera velocidad de rotación máxima.
