Abstract
(DE)
Die Erfindung betrifft eine Luftzuführvorrichtung (5) für eine Brennstoffzelle (3), mit mindestens einem Laufrad (30), das mit Hilfe einer axialen Spanneinrichtung (50) auf einer Welle (40) befestigt ist. Um die Luftzuführvorrichtung (5) funktionell zu verbessern, umfasst die axiale Spanneinrichtung (50) mindestens ein Spannelement (51) mit einer Spannfläche (53), die mit einer Gegenfläche (54) am Laufrad (30) zusammenwirkt, um das Laufrad (30) radial zu verspannen.
(EN)
The invention relates to an air supply apparatus (5) for a fuel cell (3), having at least one impeller (30) that is secured to a shaft (40) using an axial bracing device (50). In order to functionally improve the air supply apparatus (5), the axial bracing device (50) comprises at least one bracing element (51) with a bracing face (53) that interacts with a counterface (54) on the impeller (30) in order to radially brace the impeller (30).
(FR)
L'invention concerne un appareil d'alimentation en air (5) pour une pile à combustible (3), comprenant au moins une roue (30) qui est fixée à un arbre (40) à l'aide d'un dispositif de calage axial (50). Afin d'améliorer fonctionnellement l'appareil d'alimentation en air (5), le dispositif de calage axial (50) comprend au moins un élément de calage (51) présentant une face de calage (53) qui coopère avec une face opposée (54) sur la roue (30) pour caler radialement la roue (30).
