Filler means for charging containers

A filler valve assembly for filling containers within liquid products, said filler valve assembly comprising an upper body portion and a main body portion, a pressure-responsive assembly reciprocally mounted between said upper body and main body portions, spring means mounted between said pressure-responsive assembly and the upper end of said upper body, an inlet connection and opening in a side of said main body, a valve seat formed in said main body, an orifice formed just above said valve seat, said orifice consisting of a cylindrical surface formed for a predetermined height and a frusto-conical surface formed just above said cylindrical surface for a second predetermined height to accommodate the flow therepast of measured volumes of fluid products, a first valve member connected by rod means to said pressure-responsive assembly and mounted for reciprocal cooperation within said orifice, a sleeve nozzle connected to the lower end of said main body, an internally tapered flange formed at the lower end of said sleeve nozzle, a second valve member connected by said rod means to said pressure-responsive assembly for cooperation with said internally tapered flange, only one of said first and second valve members being urged by said spring means into engagement with one of said respective valve seat and internally tapered flange until such time as a measured volume of fluid product is communicated from a source of fluid product through said inlet opening to said main body, to thereby urge said pressure-responsive assembly upwardly against the force of said spring means and the first and second valve members away from said respective valve seat and internally tapered flange with said first valve member being moveable within said orifice a distance corresponding to the measured volume per unit time while forcing an equivalent measured volume of fluid product through the space between said second valve member and said internally tapered flange into the containers.
