Abstract
A rotary disc valve includes a valve housing. The housing includes a valve body having multiple ports and a lid that closes one end of the valve body. In addition, the valve may include a diverter and seal assembly disposed in the housing, the seal assembly providing a seal between the diverter and the valve body. In at least one rotational orientation of the diverter, the diverter is configured to divert fluid flow circumferentially along a first circumferential fluid path portion between a first subchamber and a second subchamber disposed between the rotational axis and the sidewall and divert fluid flow circumferentially along a second circumferential fluid path portion between a third subchamber and a fourth subchamber disposed between the rotational axis and the sidewall. The second circumferential fluid path portion is disposed radially outward with respect to the first circumferential fluid path portion.
