Definitions

  • the invention relates to an automatic inflator for a diving life jacket.
  • the scuba reducing valve connected up b la ssysteme for a life jacket are widely known and in practice. It is operated manually.
  • the vest is used either for taring the diver and can be used in an emergency situation for full inflation and quick exhaustion.
  • the life jacket is inflated by manually actuating a valve connected to the medium pressure outlet.
  • the life jacket is emptied by actuating the valve connected to the vest corrugated hose.
  • the invention has for its object a valve for an automatic to create the life jacket that comes into play when the diver's breathing is greatly reduced or stopped.
  • the inflation valve is also intended to enable the life jacket to be inflated and emptied manually.
  • this is achieved in that a time delay element which is operatively connected to a breathing sensor, the movable part (5, 6) of which, when there is no breathing, shifts against the braking effect of the time delay element and thereby moves on Inflation valve (15) opens.
  • the time delay element can work according to the hydraulic or mechanical principle, or take advantage of the laminar friction of a very viscous liquid. Manual or automatic locking can ensure that the blow-off valve is blocked in the air.
  • the automatic inflation valve shown in the drawing comprises a housing 1, a cylinder 2 and a connecting pipe 7 between the housing 1 and the cylinder 2.
  • the housing 1 is closed by a cover to which the breathing air pressure hose is connected by means of the union nut 21 and leads to the low pressure outlet of the first stage of the regulator.
  • An annular, elastic membrane 9 is clamped between the cover 8 and the housing 1, which together with the stop plate 5 which can be pushed back and forth in the housing 1 and the rod 6 connected to it forms the breath sensor.
  • the cylinder 2 is closed by the two cover plates 10 and 11.
  • the piston 3 with the non-return valve plate 42 and the spring washer 43 is located in the cylinder.
  • the piston 3 is connected to the rod 6 of the breath sensor, which is sealed and passed through the two cover disks 10, 11.
  • the cylinder 2 is filled with a liquid and forms a hydraulic time delay element with the piston.
  • the cellular rubber washer 12 serves as an external pressure-dependent locking device.
  • valve head The valve head
  • a valve head 4 is located on the housing 1. It is fastened by means of the valve body 14, which is screwed into the housing. In the valve body there is a tiltable inflation valve 15 which is pressed by the conical spiral compression spring 37. In a bore penetrating the wall of the valve head 14 there is a needle 23 which is provided on the outside with an actuating button 13. A return spring 16 and a sealing ring 27 are attached inside. On the left end of the valve head 4, the tube 41 for the tarring vest is pulled up and secured by means of a clamp 32. On the right on the valve head 4 there is a mouthpiece 30, which is also secured with a clip 31. In the right part of the valve head 14, in front of the exit to the emergency breathing mouthpiece 30, a valve disk 17 with a rod 18, a return spring 19 and an actuating button 20 attached to the outside is provided.
  • the stop plate 5 is on the left at the stop of the lid 8.
  • the lung regulator (not shown) is switched on and compressed air flows through the pressure hose 22 and through the gap between the membrane 9 and the stop plate 5 into the space 33 of the automatic inflator . Due to the pressure difference between the space 33 and the outside, the rod 6 of the breathing sensor slowly moves to the right, braked by the liquid 34, which has to flow around the piston 3. If there is no breathing from the regulator, the rod 6 continues to the right until the collar of the stop plate 5 opens the inflation valve 15. Compressed air now flows through the valve body 14 into the valve housing 4 and from there through the corrugated hose 41 into the life jacket.
  • the reduction in pressure will then cause the movement of the stop plate 5 and rod 6 by elastic expansion of the air volume 33 now sealed in the connecting tube 7. This movement will move the rod 6 with the stop plate 5 to the left with each inhalation and make it impossible to open the inflation valve 15 during the normal dive.
  • the membrane 9 leaves when the pressure rises, for example when Submerge or when the inflation valve 15 is open, air into the room 33.
  • the diver can also inflate the life jacket at his own discretion by pressing button 13,
  • the automatic inflator for the diving life jacket gives the diver additional security against diving accidents.
  • the equipment is simple, does not require any special operation and is integrated in the currently used diving life jacket so that the diver can maintain his previous habits when handling it.
