The patent application (Publication Number: US20240034545A1) describes a torque converter with a unique cap design. The torque converter includes an impeller with an impeller shell and hub, along with a cap that can slide onto the impeller hub.

Furthermore, the cap design also includes an outer ring portion that defines a channel with the inner ring portion, allowing for the impeller hub to fit in the installed position. The outer ring portion is positioned between the end of the inner ring portion and the base, providing stability to the cap structure. Overall, the cap design for the impeller hub of the torque converter offers a secure and efficient solution for retaining the cap in place while also allowing for fluid absorption and proper alignment within the torque converter system.
