ABSTRACT:
The present invention provides a unitary diverter/bypass valve. The valve has a housing which includes a chamber which is rotationally symmetric about one axis. A damper is mounted within the housing so that the damper is rotatable about the axis of the chamber. A pair of actuatable stops stop the damper from rotating in a preferred direction in either of two positions, one such position being a diversion position, and the other a bypass position. A primary inlet is located in the housing so that the axis of the inlet is offset from the axis of the chamber. As a result, fluid entering the chamber through the primary inlet tends to rotate the damper in the preferred direction. The position of the damper controls the flow of fluid to a diversion outlet, in which the fluid reenters the valve and exits through a primary outlet, or directly to the primary outlet, bypassing the diversion flow path.
