ABSTRACT:
Embodiments of the invention provide a diverter valve and a method of providing debris resistance in a diverter valve. The diverter valve can include a valve housing defining a valve chamber and at least an inlet port and an outlet port. The diverter valve can include a flow diverter extending into the valve chamber and pivotally coupled relative to the valve housing about a pivot axis defined through the valve chamber. The flow diverter can include a main portion extending into the valve chamber and a plunger portion disposed outside of the valve chamber. The main portion can have a diverting wall radially spaced apart from the pivot axis. The flow diverter can include a rib extending radially inwardly from the diverting wall toward the pivot axis. The diverter valve can also include at least one wing member positioned within the inlet port and secured relative to the valve housing.
