Abstract

PURPOSE: To prevent the facing abrasion and burning thus to reduce the shock, by providing a lock-up speed regulating means for varying the volume of oil in accordance with the car speed in a drain path for draining the hydraulic pressure in a lock-up chamber.
CONSTITUTION: When a clutch facing 19 in a lock-up mechanism 17 contacts with the end wall of a converter cover 6, a lock-up chamber 27 and a torque converter chamber 63 are formed at the both sides of a lock-up clutch piston 20. While a plunger 32b is provided in a lock-up speed regulating valve 32, and a path 58 is conducted through two orifices 32c, 32d with a drain port 32e. Consequently the facing abrasion and the burning due to the slipping of the lock-up meachanism 17 can be eliminated while the shock at the lock-up can be reduced.
