ABSTRACT:
Simple passage structure of a lock-up torque converter is disclosed. A first spacer is mounted within an annular space between an output shaft and a stationary sleeve to divide the annular space into a first annular chamber communicating with the inside of a turbine runner and into a second annular chamber communicating with a clutch chamber. The first spacer is formed with a first cutout mating with a radially extending drain passage formed within a pump cover and a second cutout mating with a radially extending passage formed within the pump cover and communicating with the control valve. The first cutout is open to the first annular chamber so that communication between the first annular chamber and the radial drain passage of the pump cover is provided. The second cutout is open to the second annular chamber so that communication between the second annular chamber and the other radial passage of the pump cover is provided.
