Abstract

Un dispositivo mejorado para generar y hacer utilizable el vacío en los sistemas de energía auxiliar de los vehículos, particularmente en los reforzadores de la presión de frenado en los que es utilizada la diferencia depresión entre el vacío y la presión atmosférica, teniendo al menos un estrangulador accionado por un elemento de control final en el sistema de admisión de un motor de combustión interna, con un conducto de vacío que tiene un extremo conectado al sistema de energía auxiliar y el otro extremo al sistema de admisión, entre el estrangulador y el motor, y teniendo un primer medio para medir el vacío y emitir y una señal cuando se haya tenido al menos un valor límite, caracterizado porque se provee un segundo medio para detectar por lo menos otro estado de funcionamiento del motor o del vehículo, o de ambos, y para mandar una señal en respuesta a dicho estado de funcionamiento, y porque el estrangulador (2) es controlado en dependencia de las señales de dichos primero y segundosmedios.
