Abstract:
1. A product distribution system for a farm implement, comprising: a distribution manifold having a fluid inlet and a plurality of outlets; an entrained fluid flow containing particulate matter entrained in air; and a purging fluid flow substantially free of the particulate matter to which at least one of the plurality of outlets is automatically exposed to when the at least one of the plurality of outlets is fluidly isolated from the entrained fluid flow; and a set of valves operatively associated with the plurality of outlets, each valve movable between a first position wherein the fluid inlet of the distribution manifold is in fluid communication with a corresponding outlet of the distribution manifold so as to allow product entrained in the entrained fluid flow to flow through the corresponding outlet and a second position wherein the inlet of the distribution manifold is isolated from corresponding outlet of the distribution manifold so as to prevent product entrained in the fluid flow from flowing to the corresponding outlet and wherein the purging fluid flow is in fluid communication with the corresponding outlet of the distribution manifold so as to allow air from the purging fluid flow to pass through the corresponding outlet of the valve.
