Abstract

SISTEMA DE DIRECCION ASISTIDA QUE INCLUYE UNA VALVULA "BYPASS" QUE DESVIA EL FLUIDO DEL CONDUCTO PRINCIPAL CONECTADO CON LA BOMBA Y EL MOTOR DE LA DIRECCION ASISTIDA. LA VALVULA "BYPASS" ES EMPUJADA HASTA LA POSICION DE APERTURA, DESVIANDO EL FLUIDO DEL CONDUCTO PRINCIPAL, CON UNA FUERZA QUE VARIA EN FUNCION DE LA PRESION QUE ENTRA A TRAVES DE UN ORIFICIO DESDE EL CONDUCTO PRINCIPAL. LA VALVULA RECUPERA SU POSICION DE CIERRE MEDIANTE UN MUELLE. ADEMAS, UNA VALVULA PILOTO ACCIONADA POR LA PRESION, SE ABRE PARA COMUNICAR LA PRESION DEL FLUIDO DEL CONDUCTO PRINCIPAL CON LA VALVULA "BYPASS", PARA LLEVARLA HASTA SU POSICION DE CIERRE. DE ESTA FORMA SE REDUCE LA PROPORCION DE FLUIDO QUE ES DESVIADO DESDE LA BOMBA DEL SISTEMA DE DIRECCION ASISTIDA Y, POR OTRO LADO, SE INCREMENTA LA CANTIDAD DE FLUIDO DISPONIBLE PARA EL FUNCIONAMIENTO DEL MOTOR DE LA DIRECCION ASISTIDA.
