Abstract

Un aspecto del invento crea un sistema de control para controlar el funcionamiento de al menos dos elementos, circuitos o sistemas hidráulicos separados, en que se vigilan las condiciones de presión en los elementos, circuitos o sistemas y se hacen ajustes con respecto a éstas, caracterizándose el sistema de control por incluir medios que hacen posible el establecimiento selectivo de niveles de presión de referencia característicos de condiciones de trabajo deseadas para los elementos, circuitos o sistemas, medios separados, asociados funcionalmente con cada uno de los elementos, circuitos o sistemas hidráulicos para vigilar por separado las condiciones de presión allí existentes, y medios para ajustar por separado dichas condiciones de presión de manera tal que dichas condiciones de presión sean modificadas cada una por separado para mantenerlas o devolverlas al nivel de presión de referencia asociado.
