  • Sequencing spray arm assembly for a dishwasher
    Patent number: 8282741
    Abstract: A sequencing spray arm assembly includes a plurality fluid spray arms rotatably mounted on respective radially spaced carrier arms. The rotating fluid spray arms are in fluid communication with a fluid distribution manifold and adapted to distribute washing fluid throughout a washing chamber of the appliance. A sequencing diverter valve system enables delivery of washing fluid from the fluid distribution manifold to one or more of the plurality of rotating fluid spray arms. A fluid responsive rotating drive arm drives the rotation of a sequencing disk in the valve system between discrete positions and enables delivery of fluid to one or more of the plurality of rotating fluid spray arms in a sequential manner such that, for each discrete position, less than the total number of spray arms are supplied with washing fluid at a time.

  • Sequencing diverter valve system for an appliance
    Patent number: 7914625
    Abstract: A sequencing diverter valve system in a washing appliance includes a fluid distribution manifold having a fluid inlet for receiving washing fluid and a plurality of fluid outlets. A fluid responsive rotating drive arm is connected to a drive reduction mechanism which, in turn, is operatively connected to a rotating sequencing valve for shifting the valve through a plurality of discrete positions at a rate of rotation less than the rate of rotation of the drive arm. As it rotates, the sequencing valve sequentially directs the washing fluid to a respective one or more of the plurality of fluid outlets.
