There is disclosed a filling valve for incorporation in a bottle filling machine such as the Crown bottle filling machine or other functionally similar bottle filling machine, which The filling valve has a housing adapted so that the liquid beverage will flow through the valve orifice from a reservoir and further through a bottle sealing rubber into the bottle or other container. A valve stem centrally located in the valve has a passageway extending through it which permits gas displaced from the container as it is filled to pass upward through the stem into the reservoir. A distinctive valve stem guide is provided in the housing which has a non-circular opening, preferably a generally triangular opening, which serves to restrain rotational movement of the stem by virtue of a hexagonal shape, or other polygonal shape, of the cross-section of a portion of the stem. A drip stopper in the valve includes a slidably mounted, generally conically shaped element which in its upward position obstructs the opening for liquid flow and in its lower position provides a large annular area for rapid flow of liquid. The drip stopper is urged with a modest force to an upward position by a spring that is overcome by the unbalanced pressure existing during the filling mode before the liquid in the container has reached the desired fill level.

[ What is claimed is:] [1.]1. A filling valve for filling containers with liquid from a pressurized bowl, said valve comprising:an elongated vertical housing;a filling orifice through said housing;a liquid valve seal element arranged within said housing and shiftable on and off a valve seat for selectively preventing and permitting flow through said filling orifice;a stem extending longitudinally through said housing having a gas flow conduit therethrough;an upper stem guide and a lower stem guide retaining said stem centrally in said housing with at least limited freedom to shift longitudinally in said housing;said stem having a polygonal cross-section for a portion of its length and said lower stem guide having a hole with a different larger area polygonal cross-section causing said stem to be restrained from rotation relative to said lower guide and said housing while leaving a passage for liquid through said lower guide;a drip stop element having a generally circular cross-section and an opening therethrough mounted on a lower portion of said stem for slideable movement thereon;a spring arranged to urge said drip stop element upward relative to said stem; anda seat in said housing against which the periphery of said drip stop element is urged to close off low pressure liquid flow through said housing.
