Abstract

Aparato de control para uso en sistemas de control de presión de fluidos que tiene una bomba de desplazamiento variable y un motor arrastrado por la misma, comprendiendo el aparato de control: (a) una unidad de accionamiento que tiene medios para responder a una señal de control de dicho circuito de control y para ajustar el desplazamiento de la bomba de una manera dependiente del valor de dicha señal, (b) una unidad de control que tiene: (i) medios para detectar la presión de fluido en el circuito de presión de fluido entre la bomba y el motor, (ii) un regulador para controlar el valor de dicha señal en el circuito de control, y (iii) medios de transferencia previstos para responder a los medios detectores para ajustar el regulador para reducir el valor de dicha señal cuando aumenta dicha presión de fluido en el circuito de presión de fluido, por lo que la unidad de accionamiento efectúa, durante su uso, un ajuste correspondiente al desplazamiento de la bomba.
