AI Technical Summary

Benefits of technology

The present invention provides a method for improving the performance (flow characteristics) of a hydraulic power system used in vehicles such as automobiles. By adjusting certain parameters like vane angles and grooves within specific areas along the blair's surface, the fluid flows smoothly through the engine valves during operation while maintaining good efficiency. Additionally, adding materials into one area reduces the amount of space needed around the rotating parts, resulting in improved fuel economy and reducing costs associated therewith. Overall, this technology helps improve vehicle drivability and reduce emissions levels.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the performance of certain type of torsional coupling used with vehicles' transmissions during start-up conditions due to imprecise or asymmetric distribution of torqued forces across different parts within these systems.
