Definitions

  • the present invention relates, in general terms, to a method and apparatus for use in the sealing, or more correctly re-sealing after damage, and/or deflation of an inflatable article. More particularly, but not exclusively, the invention relates to a method and apparatus for use in the sealing of an inflatable tyre, of the type utilized in any form of wheeled vehicle, as for example an automobile, truck, lorry, van or the like, as well as in motor-cycles, bicycles, etc.
  • a sealant mixture or compound may be introduced into a deflated tyre, as for example via a conventional tyre valve associated therewith, such sealant compound functioning to seal any puncture (or punctures) existing in the tyre itself, whereby to allow for such tyre to be subsequently re-inflated to a pressure at which it will be possible to again move the relevant vehicle, as by the driving thereof.
  • the use of such sealant compounds has been found to allow for at least a temporary repair for a thus damaged tyre or (tyres), whereby to allow the vehicle to be transported or moved to a location where a more permanent repair, or actual replacement, if necessary can be effected.
  • a suitable sealant compound (of any known type), as housed within a suitable container therefor, may be dispensed from that container under pressure and then directed into the tyre, via a tyre valve (again of any known type) invariably associated therewith. This may be achieved either with, or more preferably without, removal of the valve insert.
  • the practice is to provide an apparatus wherein means are included to allow for connection of the container to a source of air or other gas under pressure, as for example a compressor or even a gas bottle.
  • the principle of operation is that, by increasing the air pressure within the container, for the sealing compound the contents thereof can be dispensed therefrom and injected into the tyre, itself to perform a sealing action.
  • the present invention seeks to address the problems associated with the prior art by providing an apparatus wherein there is substantially no possibility of back- flow occurring, in the instance of the dispensing of sealing compound being interrupted in any way. With such an apparatus the integrity of any means employed for pressurising the container of sealing compound, whereby to allow for egress of such compound therefrom, is maintained at all times.
