Definitions

  • 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.
  • the present invention relates generally to apparatus for filling bottles and similar receptacles, and more particularly to apparatus of this type utilizing so-called counterpressure filling heads.
  • Apparatus utilizing such filling heads operates automatically, and the filling heads are provided with valves which close when the filling of a bottle is completed and remain closed until the next bottle is in place for filling with liquid from the filling head.
  • the filling heads are provided with valves which close when the filling of a bottle is completed and remain closed until the next bottle is in place for filling with liquid from the filling head.
  • the'valve is still in open position so that further inflow of liquid into the bottle is prevented only by the presence of the compressed air in the latter.
  • Still a further object of the invention is to provide an apparatus of the type in question which is capable of being utilized with existing bottling and analogous machines.
  • an apparatus for filling bottles and similar receptacles with liquid of wall means which defines a passage having an inlet for receiving liquid from a source, and an outlet arranged to be placed in communication with the interior of the receptacle.
  • An annular valve seat surrounds the passage inte'riorly thereof and a valve member is movable into and out of engagement with the valve seat between a valve-closing and a valve-opening position for respectively preventing and permitting the flow of liquid through the outlet.
  • a venting conduit having an inlet opening which extends into a receptacle with which the outlet communicates for venting of gas from the interior of the receptacle in response to admission of liquid into the latter and until such time as the level of liquid in the receptacle rises to and closes the inlet opening with attendant development of a cushion of compressed gas above the liquid level which prevents continued flow of liquid through the outlet.
  • throttling means defining in this passage at least one annular throttling gap so dimensioned as to prevent penetration of the compressed gas through the liquid in the passage and out of the inlet of the passage.
  • the annular throttling gap according to the present invention is capable of fulfilling the above-mentioned requirements.
  • the liquid in it will have adequate surface tension to prevent the pressure of the compressed gas cushion from disrupting the surface tension and from allowing the gas to escape.
  • the more even and less flow of liquid through the annular gapshaped opening makes the latter much less susceptible to clogging by solids, particularly the largely stringy pulp components, than is the case with otherwise configurated openings, for instance round bores, openings in fine-mesh grids, and the like.
  • FIG. 1 is a fragmentary sectional elevation showing the lefthand side of an embodiment according to the present invention in filling condition
  • FIG. 2 is a view similar to FIG. 1, but showing the right-hand side of the same apparatus with the valve member in closing position.
  • reference numeral 1 identifies a valve housing of a filling head for use in an apparatus for filling bottles and similar receptacles with liquid.
  • Such apparatus is already well known i.e., by US. Pat. No. 2,862,528 and is not shown or described because it does not in itself constitute a part of the present invention.
  • a source of liquid identified with reference numeral l3 and shown only diagrammatically by the chain lines.
  • the configuration or type of the receptacle containing the liquid is of no importance for purposes of the present invention, the only requirement being that there is a source from which liquid enters into the passage P.
  • the passage P is provided with an outlet opening 2 which is bounded at the exterior by a conically tapering surface la configurated so as to tightly and sealingly extend into an inlet opening of a receptacle R.
  • the receptacle is again identified only diagrammatically by the chain lines, and could be a bottle, a jar or any other receptacle which is to be filled with the apparatus in question.
  • a value member 3 movable in the direction of the double-headed arrow between a retracted position in which the valve is open and liquid passes from the source 13 through the passage P and through the outlet 2 into the interior of the receptacle R, and a valve-closing position in which a sealing element 4, for instance of elastomeric material, which is carried by the valve member 3 engages a valve seat 12 (see FIG. 2) which surrounds the passage P upstream of the outlet opening 2.
  • the closed position of the valve member 3 is illustrated in FIG. 2, and it will be understood that in this position a receptacle R associated with the device has been filled to the desired level and is being removed and is ready to be replaced by an empty receptacle.
  • throttling means which defines, in the illustrated embodiment, two annular throttling gaps 8 and 10.
  • the gap 8 is defined between a ring member 7 which is mounted in the interior of the passage P surrounding the valve member 3 with clearance, as illustrated, and an annular end face 7 of which defines the throttling gap 8 of annular configuration with an annular surface portion 9 of the internal surface of the valve housing 1.
  • the annular throttling gap 10 is defined between the inner circumferential surface 11 of the ring member 6 and a circumferentially extending surface portion 3a of the valve member 3.
  • the device is mirror-symmetrical, that is that the right-hand side of the device is similar to the left-hand side illustrated in FIG. 1.
  • FIG. 2 which differs from FIG. 1 only in that the valve member 3 is shown in its valve-closing position in which of course the inlet opening of the venting conduit 5 is located deeper in the receptacle R because the conduit 5 is carried by and moves with the valve member 3.
  • FIGS. I and 2 The operation of the device illustrated in FIGS. I and 2 will be evident.
  • the valve member 3 When the valve member 3 is in the position illustrated in FIG. 1, liquid passes from the source 13 through the passage P past the valve seat 12 and through the outlet opening 2 into the interior of the receptacle R. It continues to do so until the level of liquid, identified with reference character L in FIG. 1, rises to or just above the inlet opening of the venting conduit 5. Until this time air displaced from the interior of the receptacle R was able to escape through the conduit 5 to be vented from the same in suitable manner, for instance to the ambient atmosphere. Now, however, the level L provides a liquid seal at the inlet opening of the conduit 5, preventing the further escape of residual air from the receptacle R.
  • the compressed gas is reliably prevented from escaping until such time as the valve member 3 moves to valve-closing position as shown in FIG. 2 and the filled bottle is removed.
  • the slightly higher liquid level shown in FIG. 2 versus that shown in FIG. 1 is the result of continued inflow of liquid after the level has reached the outlet opening of the conduit 5, because some additional liquid can then still enter until the pressure of the residual gas above the level L is sufficient to prevent further inflow.
  • a combination comprising wall means defining a passage having an inlet for receiving liquid from a source, and an outlet arranged to be placed in communication with the interior of a receptacle; an annular valve seat surrounding said passage interiorly thereof; a valve member movable into and out of engagement with said valve seat between a valve-closing and a valve-opening position for respectively preventing and permitting the flow of liquid through said outlet; a venting conduit having an inlet opening extending into a receptacle with which said outlet communicates for venting of gas from the interior of the receptacle in response to admission of liquid into the latter and until such time as the level of liquid in the receptacle rises to and closes said inlet opening with attendant development of a cushion of compressed gas above the liquid level which prevents continued flow of liquid through said outlet; and stationary throttling means defining in said passage throttling means comprises an annular member stationarily mounted in said passage and surrounding
