ABSTRACT:
A distribution valve includes a housing having an upper fluid inlet, a plurality of bottom fluid outlets, and enclosing a plurality of bottom fluid outlets, and enclosing a rotary impeller disposed directly beneath the fluid inlet, 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, 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. angle, sequentially displacing each of a plurality of spherical valve balls from its seat in the bottom of the housing. The radius of the cam from its eccentric point to the point of initial contact with each valve ball is shorter than the radius to subsequent contact points to obtain higher initial mechanical advantage.
