ABSTRACT:
A liquid discharge nozzle for container filling valves includes an inner member and an outer member which together define an upstream section of a passage for the flow of the liquid to be filled into a container therethrough in the downward direction. The outer member has a valve seat cooperating with a valve member to open or close the passage. The outer member forms a groove which accommodates the lower part of the inner member to form a siphon-type trap therewith, the groove being separated from a downstream section of the passage, which is situated in the discharge nozzle portion of the outer member, by a ridge. A plurality of openings, such as notches or bores, is provided through the ridge in substantially radial directions, each of the openings extending from the groove to slightly upwardly of the valve seat. The openings have such dimensions that surface tension of the liquid present therein prevents gases from penetrating through such openings into the upstream section of the passage.
