Abstract
A vehicle driveline component includes a torque converter including an actuator and a clutch. The actuator includes an actuator piston slidable within an actuator chamber and dividing the actuator chamber into loosening and tightening chambers. The actuator piston moves the stator blades between a plurality of pitch positions. The clutch selectively couples the turbine to the impeller. The clutch includes a spring and clutch piston. The clutch piston at least partially defines an apply chamber and a release chamber. The apply chamber is in fluid communication with the tightening chamber via a hydrodynamic chamber. The release chamber is in fluid communication with the loosening chamber. The clutch piston is movable between an engaged position which inhibits relative rotation between the housing and the turbine and a disengaged position permitting relative rotation. The clutch spring is supported by the turbine hub and biases the clutch piston toward the disengaged position.
