Definitions

  • This invention relates to breathing apparatus for use by a scuba diver.
  • GB 2 037 587-A and EP 0 278 598-A both disclose breathing apparatus which comprises:
  • the present invention proposes that the apparatus has the features stated in the characterising part of Claim 1.
  • the drawing is a diagrammatic sectional view of scuba diving apparatus of the invention.
  • the apparatus includes a valve body 1 provided with an inlet coupling 2 for connection via a quick-release device 3 and a high pressure hose 4 to a reservoir of compressed air (not shown).
  • the coupling 2 communicates with a breathing chamber 20 via a spring-loaded demand valve 10.
  • a mouthpiece 30 opens into the chamber 20, and a diaphragm 12 is sealably mounted in the wall of the chamber 20, exposed to external water pressure.
  • the diaphragm is coupled to the demand valve 10 via a lever 14 such that when the diver breathes in through the mouthpiece 30, the diaphragm moves inwards and opens the valve 10 via the lever 14 to admit air to the diver.
  • a one-way exhaust valve 40 which is biassed closed by a spring 42, allows air to pass into a secondary chamber 50, from which it escapes via an exhaust port 60.
  • the valve body 1 is provided with a large-bore buoyancy conduit 66 for connection to a jacket or similar inflatable buoyancy device (not shown) via flexible hose 80.
  • the conduit 66 communicates with the secondary chamber 50 via a buoyancy valve 100 which is connected to a push rod 92.
  • the rod 92 extends through the port 60 to carry a manual actuator button 90, which in turn contains a bias spring 94 acting between the button and the valve body 1 to bias the buoyancy valve closed.
  • the valve 100 thus prevents air from passing to or from the buoyancy conduit 66, but the jacket can be inflated for increased buoyancy by operating an inflate button 70 to admit air from the inlet coupling 2 along a passage 72 to the buoyancy conduit 66.
  • Deflation of the jacket is achieved by partial depression of the actuator button 90, sufficient to open the valve 100 and allow air out through the chamber 50 and exhaust port 60.
  • the diver can also exhale into the jacket to inflate it manually, which is normally carried out at or above sea level when there is little or no water pressure on the jacket. This is achieved by fully depressing the actuator button 90 until the exhaust port 60 is closed by a seal 96 on the button, and the valve 100 is opened to connect the secondary chamber to the buoyancy conduit.
  • the buoyancy device can now be inflated by air exhaled through the exhaust valve 40.
