Abstract: A fluid distribution apparatus includes an impeller-driven gear reduction mechanism and a plurality of outlet valves controlled in response to the gear reduction mechanism. Each valve includes a hollow stationary cylinder with an open top and an open bottom in fluid communication with a respective outlet port. Each stationary cylinder includes a side port. Each valve also includes a hollow rotating cylinder positioned inside the stationary cylinder and having a closed top connected to a valve drive gear driven by the gear reduction mechanism. Each rotary cylinder has an open bottom that communicates with a respective outlet port of the fluid distribution apparatus. Each rotary cylinder also includes an inlet port that overlaps the inlet port of the corresponding stationary cylinder during a portion of a 360 degree rotation of the rotary cylinder.

Abstract: A distribution valve includes a housing having an upper fluid inlet, a plurality of bottom fluid outlets and enclosing a rotary impeller disposed directly beneath the fluid inlet, and a plurality of stationary baffles disposed between a bottom plate of the impeller and the fluid inlet for directing portions of the incoming fluid directly at a plurality of vertical vanes supported at the bottom plate of the impeller. A stationary planetary gear disposed about a vertical axis of the distribution valve engages a pair of symmetric gear assemblies supported on a rotary gear assembly base and each driven by a drive gear attached to the impeller. A foot-shaped cam is attached to the lower portion of the rotary gear assembly base and rotates through a 360.degree. angle, sequentially lifting each of a plurality of spherical valve balls from its seat in the bottom of the housing.

A stationary planetary gear disposed about a vertical axis of the distribution valve, a pair of symmetric gear assemblies each driven by a drive gear attached to the impeller, each of the symmetric gear assemblies being supported on a rotary gear assembly base, and each also having an outer gear engaging the teeth of the planetary gear cooperate to cause the rotary gear assembly base to rotate in response to rotation of the impeller. A foot-shaped cam is attached to the lower portion of the rotary gear assembly base and rotates through a 360.degree.
