Abstract

L'invention concerne un limiteur de cylindre de frein ayant une première partie qui détermine la pression de cylindre de frein réelle et une seconde partie qui détermine la pression de cylindre de frein voulue, en fonction de la réduction de la pression de la conduite de frein. Les deux parties sont combinées de telle sorte que la pression du cylindre de frein soit évacuée si la pression de cylindre de frein réelle est supérieure à la pression de cylindre de frein voulue selon une quantité de seuil prédéterminée, qui représente de préférence deux fois et demi la réduction de la pression de la conduite de frein. Une soupape de coupure d'échappement peut être utilisée pour empêcher l'évacuation de la pression de cylindre de frein si elle tombe au-dessous d'une valeur prédéterminée.
