US Patent 12013048 Rotary disc valve

A rotary disc valve is used in a fluid delivery system to control flow of fluid between multiple ports. The valve may include a valve body having multiple ports that are connected to the system. In addition, the valve may include a diverter and seal assembly that are disposed in the valve body. The diverter is configured to rotate about a rotational axis and to control fluid flow through the valve body. The valve is free of an axial compression spring, and the valve body, the lid and the diverter are shaped and dimensioned so that an interference fit exists between the lid and the diverter that results in compression of the seal assembly between the diverter and the base.
