Abstract: A variable position diverter that provides wash fluid to selected combinations of outlet ports and spray assemblies. The diverter includes a housing having a first fluid outlet, a second fluid outlet, and a valve disk having four apertures. The valve disk is rotated relative to the housing to align one or more of the four apertures with one or both of the first fluid outlet and the second fluid outlet to selectively control the flow of wash fluid through corresponding spray assemblies. Selectively diverting wash fluid in this manner can improve wash performance and reduce cycle time while meeting government regulations regarding water usage.

Abstract: A passive diverter is provided that does not require a dedicated motor to switch between multiple outlet ports. The diverter uses the forces provided by a flow of fluid from a pump to switch between different outlet ports and supply one or more spray assemblies or other fluid-using elements. A separate motor to power the diverter is not required, which allows a savings in costs and space. In addition, a secondary set of ramps may provide a manner in which to “zero” the angular position of the diverter, i.e., place the diverter in a known, home position. This can reduce the additional cost, weight, and complexity of including additional sensors to determine the angular position of the diverter.

Abstract: A passive diverter is provided that does not require a dedicated motor to switch between multiple outlet ports. The diverter uses a flow of fluid provided by a pump to switch between different outlet ports. In a dishwashing appliance, fluid from the pump that supplies one or more spray assemblies can be used to cause the diverter to switch between different fluid outlets and e.g., different spray assemblies. A separate motor to power the diverter is not required, which allows a savings in costs and space.
