Abstract

Un dispositivo asimétrico para incrementar el volumen incluye un accionador desplazable en una primera direccion y en una segunda direccion, un primer incrementador de la comunicacion fluida con el accionador, y un segundo incrementador de la comunicacion fluida con el accionador. El primer incrementador incluye un primer pasaje de alimentacion y un primer pasaje de evacuacion, donde el primer pasaje de alimentacion suministra fluido al accionador y el primer pasaje de evacuacion descarga el fluido del accionador. El primer pasaje de evacuacion está configurado para producir una primer resistencia al flujo de fluidos. El segundo incrementador incluye un segundo pasaje de alimentacion y un segundo pasaje de evacuacion, donde el segundo pasaje de alimentacion suministra fluido al accionador y el segundo pasaje de evacuacion descarga el fluido del accionador. El segundo pasaje de evacuacion está configurado para producir una segunda resistencia al flujo de fluidos. La primera resistencia al flujo de fluidos es mayor que la segunda resistencia al flujo de fluidos, de modo tal que el accionador se traslada en forma sustancialmente simétrica en la primera direccion y en la segunda direccion.
