ABSTRACT:
A filling valve assembly for filling a container (11) with a fluid material and comprising a valve body (16) having an outer wall (18) defining an inner chamber (20). A vent tube (30) extends upwardly through the chamber (20) for ventilating the container (11) when the container (11) is filled with the fluid material and defining at least one fluid passageway (38) disposed between the outer wall (18) and the vent tube (30) for allowing the fluid material to discharge from the chamber (20) and into the container (11). A first screen (62) is disposed across said fluid passageway (38) and the assembly is characterized by a second screen (64) disposed across the passageway (38) in spaced relationship to and below the first screen (62) whereby the capillary action of both screens (62) and (64) accumulate to more precisely fill successive containers (11) to equal volumes.
