装置。 When the lock-up switching valve 17 is opened, hydraulic pressure is applied to the back surface of the piston 1, and the piston 1 presses against the friction plate 2 provided between the flywheel 3 and the turbine shaft 4, forming a lock-up clutch mechanism. In a lock-up clutch with a built-in torque converter, which is constructed by interposing an orifice 13 and an accumulator 14 in a lock-up clutch operating hydraulic circuit 20, a lower port E of the body 15 of the accumulator 14 is provided.
A branch circuit 18 branching off the torque converter supply circuit is connected to the main body 15, and a side port D provided on the side of the body 15 is connected to the lock-up clutch operating hydraulic circuit 20 by a connecting circuit 19. Features a lock-up clutch hydraulic control device.
