Abstract

L'invention concerne les freins du type comprenant un amplificateur d'effort de freinage équipé d'une soupape de commande qui est destinée à l'application de la pression d'un accumulateur comme force auxiliaire pour l'amplificateur, lequel alimente au moins un circuit de frein. Un frein selon l'invention comprend une soupape de commutation 31, à travers laquelle une liaison directe peut être établie entre un accumulateur hydropneumatique 15 et un circuit de frein II.The invention relates to brakes of the type comprising a brake force amplifier equipped with a control valve which is intended for applying the pressure of an accumulator as an auxiliary force for the amplifier, which supplies at least one. brake circuit. A brake according to the invention comprises a switching valve 31, through which a direct connection can be established between a hydropneumatic accumulator 15 and a brake circuit II.
