<p>A power transmission mechanism includes a hydrokinetic torque converter driven by a hydraulically actuated modulating friction clutch having a piston disposed in and sealingly engaged with the converter housing to form opposed fluid chambers. Fluid in the torque converter housing flows through an orifice between the chambers and exits the converter housing by way of a flow control valve. A pressure differential is imposed on the piston by controlling the outflow of fluid from one of the chambers to modulate clutch engagement for varying the power output of the torque converter.</p> |
