Definitions

  • the invention relates to an extractor tube intended for use in a container that contains a pressurised beverage, which extractor tube is provided with a housing to be fitted in the container, which housing is provided near one end thereof with a valve seat that is to mate with a ring-shaped sealing element present on one end of a tube supported by the housing, which is movable against spring pressure in a direction away from the valve seat, in which tube a valve disc supported by the tube is positioned, which valve disc is movable against spring pressure in a direction away from the valve seat and which can mate with a sealing edge formed on the ring-shaped sealing element, which sealing element comprises a ring-shaped elastomeric body that is covered, at least near its upper side facing towards the valve seat, by a metal ring that is provided with a flanged portion at its outer circumference for being supported on the valve seat, whilst a part of the elastomeric body that is located near the bottom edge of the flanged portion has a larger external diameter in
  • Such an extractor tube is known from Dutch patent No. 1002143.
  • the flanged edge of the metal ring takes up most of the forces that are being exerted on the sealing element, whilst the part of the elastomeric body that is located near the bottom edge of the flanged portion of the metal ring is pressed against the valve seat so as to effect a seal .
  • the elastomeric body is retained between an upper end of the tube, the metal ring and a jacket that joins the inner circumference of the metal ring.
  • this known extractor tube has been satisfactory, but in some applications it has become apparent that the elastomeric body is not sufficiently stable to meet the requirements that are made thereof, in particular after prolonged use.
  • a jacket-like body is fixed to the metal ring, which body is at least substantially entirely embedded in the elastomeric body over its height.

  • An elongated tube 2 is supported in the housing 1, which tube comprises a part 3, which extends into the container during use of the extractor tube, and a part 4 having a slightly larger diameter, which is surrounded by the housing 1.
  • said part 4 is provided with a part 5 having a diameter slightly larger than that of the part 4.
  • the part 4 of the tube is surrounded by a spiral compression spring 6, which is supported on a supporting ring 7 fitted in the housing 1 with its bottom end and which abuts against the transition between the part 4 and the part of 5 of the tube 2 with its upper end.
  • a ring-shaped sealing element 8 is fitted in the upper apart 5 of the tube.
  • said sealing element 8 comprises a metal ring 9, whose outer edge 10 is flanged in downward direction, in such a manner that said part 10 forms part of the surface of a cone.
  • a jacket-like or tubular body 11 joins the bottom surface of the metal ring 9, being welded thereto, in which body a gap 12 extending along the height of the jacket-like body 11 is present.
  • the jacket-like body is circumferentially provided with regularly spaced holes 13, said holes being spaced from the metal ring 9 by some distance.

  • the elastomeric body 15 will also extend through the aforesaid holes 13 and the slotted holes 14, so that a solid connection between the jacket-like body and the elastomeric body 15 will be effected.
  • the parts of the elastomeric body 15 that are located on either side of the jacket-like body 11 are furthermore interconnected by regularly spaced-apart connecting elements 16 extending below the bottom edge of the jacket-like body 11, seen in Fig. 5.
  • the elastomeric body 15 is furthermore provided with a circumferential nose that projects beyond said edge 10 in the unloaded condition of the elastomeric body.

  • the sealing element 8 In mounted condition, the sealing element 8 will abut against a valve seat 22 formed on the inner circumference of the housing 1 if no further forces are exerted on the various parts described above, with the flanged edge 10 of the metal ring 9 abutting against said seat 22 and taking up most of the forces exerted by the spring 6.
  • the nose 17 that projects beyond the flanged edge 10 is slightly deformed as a result of being pressed against the valve seat 22 so as to effect an adequate seal.
  • the spring 21 sealingly presses the valve disc 20 against the nose 19.
  • the valve disc 20 can be pressed downwards with respect to the projecting nose 19 by means of a tap or the like.
  • the jacketlike body 11 provides an effective support of the elastomeric body 15, without the intended effective sealing action of the parts 17 and 19 of the elastomeric body 15 being adversely affected. Since the projecting nose 19 is furthermore positioned just below the ring 9, an effective support of said nose 19 for taking up the forces exerted by the spring 21 that mates with the valve disc 20 is obtained while maintaining an adequate sealing action of said nose 19 together with the valve disc 20.
  • Figs. 8 and 9 corresponds in large measure to the extractor tube according to the above-described embodiment, and consequently like parts are indicated by the same numerals in the two figures. In this embodiment, however, use is made of a more less dome-shaped valve disc 23. Furthermore, a downwardly flanged edge 24 is likewise provided on the inner circumference of the ring 9 in this embodiment.
  • the inner circumferential wall of the elastomeric body has a curved configuration, with the elastomeric body being provided with a projecting nose 25 near the part thereof that is positioned under the flanged edge 24, which nose functions to mate sealingly with the valve disc 23.
  • the sealing nose that mates with the valve disc 23 is disposed within the jacket-like body, near the upper end thereof, being effectively supported by the flanged edge 24 of the ring 9.

Abstract

La présente invention se rapporte à un tube extracteur utilisable dans un récipient renfermant une boisson sous pression, ce tube extracteur étant équipé d'un boîtier devant être installé dans le récipient, à proximité de l'une de ses extrémités où se trouve un siège de soupape coopérant avec un élément formant joint annulaire présent sur l'une des extrémités d'un tube porté par le boîtier, lequel peut se déplacer à l'encontre d'un effort élastique en s'éloignant du siège de soupape. Un disque de soupape placé à l'intérieur du tube et porté par ce dernier peut se déplacer à l'encontre d'un effort élastique en s'éloignant du siège de soupape, et venir coopérer avec un rebord d'étanchéité formé sur l'élément formant joint annulaire. L'élément formant joint comporte un corps élastomère annulaire surmonté, au moins à proximité de sa face supérieure tournée vers le siège de soupape, d'un anneau métallique pourvu d'un rebord saillant au niveau de sa périphérie externe en vue de prendre appui sur le siège de soupape. Un corps formant chemise est fixé à l'anneau métallique et au moins sensiblement entièrement noyé dans le corps élastomère sur toute sa hauteur.
