Mid-Level Dishwasher Spray Arm With Passive Flow Diverter

The diverter element is designed to rotate automatically using the kinetic energy of the fluid flow itself. The fluid passing through the spray assembly creates a reactive force that causes the diverter to pivot between different ports, eliminating the need for an external motor or power source. This self-actuating mechanism reduces both manufacturing cost and space requirements while maintaining full fluid control capability.

The invention uses hydraulic principles by utilizing the fluid flow through the spray assembly to generate the mechanical force needed for diverter rotation. The fluid pressure and flow rate create a torque on the diverter element, enabling it to switch between ports without electrical components. This hydraulic actuation system replaces the electric motor while achieving the same control function.

The spray assembly incorporates a dynamically rotating diverter element that continuously changes the distribution of fluid flow among multiple outlets. Instead of all outlets receiving fluid simultaneously, the diverter rotates to direct fluid to different outlets in sequence, creating a dynamic fluid distribution pattern that maintains cleaning effectiveness while reducing total water and energy consumption.

The diverter element performs periodic rotation between different outlet ports, creating a time-based sequence in which different outlets receive fluid flow. This periodic action ensures that all outlets are utilized for cleaning coverage while limiting the instantaneous water and energy input to compliant levels, as the system cycles through outlets rather than activating all simultaneously.
