Abstract:
1. A controllable hydrodynamic torque converter for use within a vehicle having a detectable throttle level, the torque converter comprising: a first stator having a first outlet angle; a second stator having a second outlet angle; a one-way clutch adapted for allowing the first stator and the second stator to freewheel when a redirection of fluid through the first stator and the second stator is not required; and a selectively actuatable clutch adapted for locking the first stator and the second stator at each of an idle throttle level and a high throttle level; wherein said second stator is selectively engageable with said first stator via the selectively actuatable clutch for varying the K-factor of the torque converter only when the detected throttle level is the idle throttle level or the high throttle level, and selectively disengageable from said first stator by releasing the selectively actuatable clutch only when the detected throttle level is a low or a part throttle level.
