Abstract

A hydrodynamic torque converter (1) with a lock-up clutch (6) in the form of a disk clutch in a clutch space (9) and with a piston (7) for actuating the lock-up clutch (6). The lock-up clutch (6) has an end disk (63) and a first disk carrier (61), on which the end disk (63) is radially and axially supported. The end disk (63) is arranged on the side of the lock-up clutch (6) remote from the piston (7). The lock-up clutch (6) has a second disk carrier (62). A sealing element (64) is provided, on the second disk carrier (62), a sealing gap (12) is formed between the end disk (63) and the sealing element (64).
