PCT No. PCT/EP89/01367 Sec. 371 Date May 15, 1991 Sec. 102(e) Date May 15, 1991 PCT Filed Nov. 15, 1989 PCT Pub. No. WO90/06458 PCT Pub. Date Jun. 14, 1990.In a control mechanism for a frictionally engaged lock-up clutch of a hydrodynamic torque converter, a coupling element (8) is axially displaced for engaging and disengaging the lock-up clutch (7), face end actuation spaces (10, 11) being accordingly pressurized via regulating valves (15, 16). A lubricant line (28) leads via a radiator (39) to lubrication points (40) of a change-speed gear (6) rear-mounted on the torque converter (3), the lubricant line (28) being attached to a controlled return flow of the actuation space (11). To ensure there is a sufficient supply of lubricant to the lubrication points (40) and a sufficient cooling of the pressurized fluid or lubricant in all shift conditions of the lock-up clutch (7) via the radiator (39), a leg (34) of the main pressure line (13) is attached to the lubricant line (28) before the radiator (39) which feeds a missing amount of lubricant into the lubricant line (28).
