Title
(DE) GEBERZYLINDER MIT DICHTELEMENT
(EN) MASTER CYLINDER HAVING A SEALING ELEMENT
(FR) MAÎTRE-CYLINDRE AVEC ÉLÉMENT D'ÉTANCHÉITÉ
Abstract
(DE)
In einem Geberzylinder (1) für ein Kupplungs- oder Bremssystem ist ein Dichtelement (6) zur Abdichtung eines Druckraums (3) vorgesehen. Das Dichtelement (6) verfügt über eine Dichtlippe (61) zur Abdichtung einer Zuführung (21) von Hydraulikfluid aus einem an einem Gehäuse (2) des Geberzylinders (1) angebrachten Reservoir (24) in den Druckraum (3) und über eine Dichtstruktur (63, 64) zur Abdichtung des Druckraums (3) gegen eine Umgebung des Druckraums (3).
(EN)
The invention relates to a master cylinder (1) for a clutch system or brake system, in which master cylinder a sealing element (6) for sealing a pressure chamber (3) is provided. The sealing element (6) is provided with a sealing lip (61) for sealing a feed (21) of hydraulic fluid from a reservoir (24) arranged on a housing (2) of the master cylinder (1) into the pressure chamber (3) and is provided with a sealing structure (63, 64) for sealing the pressure chamber (3) against a surroundings of the pressure chamber (3).
(FR)
L'invention concerne un maître-cylindre (1) pour un système d'embrayage ou de freinage, un élément d'étanchéité (6) destiné à réaliser l’étanchéité d’une chambre de pression (3) étant disposé dans le maître-cylindre (1). L'élément d'étanchéité (6) dispose d'une lèvre d'étanchéité (61) destinée à réaliser l'étanchéité d'une alimentation (21) en fluide hydraulique depuis un réservoir (24) monté sur un boîtier (2) du maître-cylindre (1) dans la chambre de pression (3) et d'une structure d'étanchéité (63, 64) destinée à réaliser l'étanchéité de la chambre de pression (3) par rapport à un environnement de la chambre de pression (3).
