Abstract
A filling machine including a manifold having a supply inlet and supply outlet and one or more nozzles connected to the manifold by individual time controlled valves. A circulation system is provided connecting a supply and the manifold for continuously circulating liquid through the manifold from the supply inlet to overflow the supply outlet such that the supply outlet determines the liquid level in the manifold and the head pressure at one or more nozzles. The manifold is structured to have a manifold section with a supply inlet on the manifold section and a stand pipe connected to the manifold section. The stand pipe includes the supply outlet and is vented to atmosphere. By varying the height of the stand pipe or the location of the outlet, the level within the manifold and the head pressure at the nozzles is adjusted. For sequential filling, bulk fill nozzles are controlled by a single timer and one or more fine fill nozzles are controlled by individual timers.
