Definitions

  • Striker ABSTRACT A vent device for venting a gaseous and/or vaporous medium into the atmosphere, in particular for venting such a medium from a generally enclosed liquid container when liquid is entering the container, said vent device providing a vent orifice arranged for flow therethrough of the medium being vented, and comprising means for varying the crosssectional area of the orifice in response to the volumetric rate of flow of the medium being vented, said cross-sectional area increasing with increasing flow, rate of the medium and decreasing with decreasing flow rate of the medium.
  • a vent device providing an orifice of variable cross section is arranged to control the pressure within the container so that the linear velocity of venting gaseous and/or vaporous medium leaving the container through the vent device does not fall below a predetermined minimum.
  • FIG. 3 is a front view corresponding to FIG. 2,
  • FIG. 8 is a partially sectioned side elevation of the vent device of FIG. 7, and
  • the vent device 20 is arranged to prevent the linear velocity of venting air or other gaseous medium leaving the tank 12 from falling below a predetermined minimum value when liquid is entering the tank 12 through an inlet (not shown).
  • the vent device 20 comprises a framework 22 which comprises a lower rectangular portion 24 arranged to fit in the trunk 14 and two upwardly extending triangular portions 26.
  • the device 20 also comprises two flaps 28 which extend upwardly from hinges 30 which are mounted in the portion 24 of the framework 22. In a rest condition of the device 20 the flaps 28 rest on the triangular portions 26 and are in contact with each other along upper edges 37 thereof; the upper edges of the flaps meet at an angle of not more than in this condition.
  • the device also comprises springs 32 which urge the flaps 28 about their hinges 30 into the rest condition.
  • the vent device 20 also comprises a handle 34 to facilitate its removal from the trunk 14.
  • FIGS. 7 to 9 show a preferred embodiment of a vent device in accordance with the invention.
  • This vent device which is generally designated by the numeral 80, is generally similar to the vent device 60 of FIGS. 5 and 6, the main difference between the two devices being that the device of FIGS. 7 to 9 is provided with counterweights in place of the springs of the device 60.
  • the same reference numerals have been used in FIGS. 7 to 9 to designate those items which are similar to items of the vent device 60.
  • the vent device 80 comprises a hollow framework 80a having two opposed sidewalls 81 which at their upper ends are of triangular configuration.
  • the two flaps 68a and 68b are secured to spindles 82, 83, respectively, these spindles being joumaled in the sidewalls 81.
  • counterweights 84, 85 are secured to the spindles 82, 83 respectively in order to urge the flaps 68a and 68b to their rest condition shown in FIG. 8.
  • the vent device 80 may replace the vent device 60 in the container assembly shown in FIGS. 5 and 6.
  • the flaps 68a, 68b assume the positions shown in chain lines in FIG. 8, against the action of the counterweights 84, 85, when liquid is entering the tank 52.
  • the hinged member 72b pivots into the position shown in chain lines in FIG. 8, against the action of the counterweight 88, to allow air to enter the tank 52.
  • the hinged member 72a provides an overpressure relief when the flaps 68a, 68b are in their rest condition. If an overpressure arises in the tank 52, the hinged member 720 can pivot into the position shown in chain lines, against the action of the counterweight 87, to allow relief of the overpressure.
  • a removable flame screen (not shown), similar to the flame screen 70 of FIGS. 5 and 6, may be provided in the framework 800 of the vent device 80.
