US Patent 11958336 Multi-port rotary valve

A multi-port rotary disc valve includes a valve housing having chamber walls that segregate an internal space of the housing into subchambers that each provide a portion of one or more fluid paths through the valve housing. The valve housing includes valve ports, where each valve port communicates with a subchamber and is an axially-extending through hole that resides in a plane that is common to all valve ports. The valve also includes a diverter assembly that is disposed in one of the subchambers and is configured to control fluid flow through the valve housing. The valve also includes seal assemblies disposed in the chamber so as to be aligned with the diverter assembly along a rotational axis of the diverter assembly.
