Abstract
A torque converter comprising: an axis of rotation; a first seal at a first radial distance relative to the axis of rotation; a second seal at a second radial distance relative to the axis of rotation; an impeller shell and a balancing plate defining at least a portion of a first hydraulic chamber; a piston plate sealed via the first seal to the balancing plate defining at least a portion of a second hydraulic chamber; a cover sealed to the piston plate via the second seal defining at least a portion of a third hydraulic chamber. A clutch plate is radially outward relative to the balancing plate. The sealing arrangement, effective at preventing drift-on or drift-off of the clutch due to dynamic pressure, features a first radial distance that is the same or equal to the second radial distance.
