A torque converter includes a front cover, a shield, a lock-up clutch, and a dam. The front cover is arranged to receive a torque and includes a radial portion having an orifice extending axially therethrough. The shield is non-rotatably connected to the front cover and includes an opening extending axially therethrough. The shield and the front cover define a chamber. The lock-up clutch includes a piston. The piston and the front cover define in part a compensation chamber. The dam is arranged in the chamber and sub-divides the chamber into an air chamber and a compensation reservoir. At least a portion of the dam is axially displaceable within the chamber. The air chamber is arranged between the dam and the shield and is in fluid communication with an ambient environment via the opening. The compensation reservoir is arranged between the dam and the radial portion and is in fluid communication with the compensation chamber via the orifice.

A side plate utilized in a torque converter, comprising a first annular surface, a second annular surface opposite the first annular surface, an outer race defining an outer peripheral of the first and second annular surface, an inner race defining an inner peripheral of the first and second annular surface, and a neck extending axially away from the second annular surface and located along the inner race.

Inner race centering with formed side plate

A housing for a torque converter comprising: an axis of rotation; a cover including: a first inner surface; a first outer surface opposite the first inner surface; a first axially extending necked portion radially outward relative to the axis of rotation and parallel to the axis of rotation, an impeller shell non-rotatably connected to the cover and having: a second inner surface; a second outer surface opposite the second inner surface; a second axially extending necked portion radially outward relative to the first axially extending necked portion; a line orthogonal to the axis of rotation passes through the first and second axially extending necked portions; and, a weld fixedly securing the first inner surface to the second inner surface at at least one point on the line. A torque converter including such a housing closure is also described.
