Abstract:
(EN) The invention relates to an electropneumatic parking brake control device (1) for controlling a parking brake including at least one spring brake actuator, said control device including a relay valve (18) with a control chamber (42) and a deaeration means (56). According to the invention the control chamber (42) can be connected to the deaeration means (56) via at least one second throttle element (65) and/or at least one third throttle element (66) depending on the position of the relay piston (46).
(FR) La présente invention concerne un dispositif de commande de frein de stationnement (1) électropneumatique destiné à assurer la commande d'un frein de stationnement contenant au moins un cylindre de frein à ressort accumulateur, ledit dispositif contenant une valve-relais (18) dotée d'une chambre de commande (42) et d'une purge d'air (56). Selon l'invention, la chambre de commande (42) peut être reliée à la purge d'air (56), en fonction de la position du piston-relais (46), par l'intermédiaire d'au moins un deuxième élément d'étranglement (65) et/ou d'au moins un troisième élément d'étranglement (66).
(DE) Die Erfindung betrifft eine elektropneumatische Parkbremssteuereinrichtung (1) zur Steuerung einer wenigstens einen Federspeicherbremszylinder beinhaltenden Feststellbremse, beinhaltend ein Relaisventil (18) mit einer Steuerkammer (42) und einer Entlüftung (56). Die Erfindung sieht vor, dass abhängig von der Stellung des Relaiskolbens (46) die Steuerkammer (42) über wenigstens ein zweites Drosselelement (65) und/oder wenigstens ein drittes Drosselelement (66) mit der Entlüftung (56) verbindbar ist.
