摘要： A bottle-filling apparatus includes a filling head whose outlet is to be placed in communication with the interior of a bottle or similar receptacle. Annular valve seat surrounds the internal liquid-conveying passage of the filling head, and a valve member is movable into and out of engagement with the valve seat between a valve-opening and a valve-closing position. A venting conduit is carried by the valve member coaxially therewith and extending therethrough and has an inlet opening which communicates with the interior of the bottle when the outlet of the filling head similarly communicates with the bottle. The venting conduit serves to vent gas from the interior of the receptacle in response to admission of liquid into the latter until such time as the level of liquid rises to and closes the inlet opening whereupon a cushion of compressed gas develops above the liquid level and prevents continued flow of liquid into the bottle. Throttling means is provided which defines two narrow annular gaps, spaced axially from one another, in the interior of the liquid passage of the filling head, serving to prevent the compressed gas of the cushion from penetrating and escaping through the liquid contained in the passage.
