Abstract

Perfeccionamientos en neumodistribuidores automáticos para suspensiones neumáticasespecialmente para vehículos de tres ejescaracterizados por montarse en el conducto que une las suspensiones posteriores con las del tercer eje y por contener una válvula de interceptación controlada por la presión del fluido de las suspensiones del eje posterior y que funciona para poner en comunicación estas últimas con las del eje auxiliar en cuanto la presión alcanza un valor previamente fijadoen las suspensiones posteriores.
