Abstract

Circuito hidráulico para un sistema de suspension activo de asiento. Un sistema de suspension activa para soportar una masa, tal como un asiento en una base de un vehículo, incluye un accionador hidráulico acoplado entre el asiento y la base, un dispositivo de descarga neumático entre el asiento y la base, y un sistema de control que controla activamente al accionador hidráulico y que controla al elemento de descarga. El sistema de control controla activamente al accionador hidráulico en funcion de una senal de error de posicion de asiento. Una válvula de control de flujo controla la extension y retraccion del accionador. Una válvula de control de presion proporcional está conectada entre una válvula reductora de presion primaria y una entrada de la válvula de control de flujo. Durante el arranque, la válvula reductora de presion primaria y una entrada de la válvula de control de flujo. Durante el arranque, la válvula de control de presion impide el suministro de fluido presurizado a la válvula de control de flujo hasta que la válvula de control de flujo sea impulsada a su posicion central o nula. Durante una falla de energía eléctrica, la válvula de control de presion operada a solenoide es impulsada a resorte a una posicion de cierre que impide la comunicacion de presion a la válvula de control de flujo.
