Abstract
A lock-up torque converter includes a converter cover secured to a pump impeller and a clutch piston drivingly connected to a turbine runner. The clutch piston is engageable with the end wall of the converter cover and forms therewith a clutch chamber which is adapted to be pressurized or exhausted. A feed passageway and a discharge passageway communicate with the inside of the pump impeller and with the inside of the turbine runner, respectively, and cooperate with each other to feed a pressurized fluid into the pump impeller and to discharge the pressurized fluid from the turbine runner. A third passageway communicates with the clutch chamber and a lock-up control valve. The lock-up control valve selectively pressurizes and exhausts the clutch chamber.
