Title
(DE) FAHRZEUGBREMSSYSTEM-DRUCKDÄMPFVORRICHTUNG
(EN) PRESSURE DAMPING DEVICE OF A VEHICLE BRAKE SYSTEM
(FR) DISPOSITIF D'AMORTISSEMENT DE PRESSION D'UN SYSTÈME DE FREINAGE DE VÉHICULE
Abstract
(DE) Die Erfindung betrifft eine Fahrzeugbremssystem-Druckdämpfvorrichtung (10) mit einem ersten Raum (20), an den hydraulischer Druck anzulegen ist, und einem zweiten Raum (24), der von einem Dämpfergehäuse (14) umgeben und in dem sich ein kompressibles Medium befindet, und einem Trennelement (22) zum Abtrennen des ersten Raumes (20) vom zweiten Raum (24). Dabei ist ein bezogen auf eine Längsachse (48) ringförmiges Stützelement (44) vorgesehen, mittels dem das Trennelement (22) bezogen auf die Längsachse (48) schräg nach radial außen und axial in Richtung zum zweiten Raum (24) gegen das Dämpfergehäuse (14) gedrängt ist.
(EN) The invention relates to a pressure damping device (10) of a vehicle brake system, comprising a first chamber (20), to which hydraulic pressure is to be applied, and a second chamber (24) which is surrounded by a damper housing (14) and in which a compressible medium is located, and a separating element (22) for separating the first chamber (20) from the second chamber (24). An annular support element (44) is provided with respect to a longitudinal axis (48), by means of which the separating element (22), with respect to the longitudinal axis (48), is forced obliquely and radially outwards as well as axially in the direction towards the second chamber (24) against the damper housing (14).
(FR) L'invention concerne un dispositif d'amortissement de pression (10) d'un système de freinage de véhicule, comprenant une première chambre (20), à laquelle une pression hydraulique doit être appliquée, et une seconde chambre (24) qui est entourée par un boîtier d'amortisseur (14) et dans laquelle se trouve un milieu compressible, et un élément de séparation (22) pour séparer la première chambre (20) de la seconde chambre (24). Un élément de support annulaire (44) est disposé par rapport à un axe longitudinal (48), au moyen duquel l'élément de séparation (22), par rapport à l'axe longitudinal (48), est forcé obliquement et radialement vers l'extérieur ainsi qu'axialement dans la direction vers la seconde chambre (24) contre le boîtier d'amortisseur (14).
