Definitions

  • the invention relates to a respirator for SCBA, with an automatic regulator, which is controlled by a control membrane, and an exhalation valve with air outlet.
  • Respiratory masks are usually operated in conjunction with a compressed air breathing apparatus with a lung machine, which is connected via a screw or plug connection with the mask body.
  • This understandably highly sensitive, thin membrane made of an elastic material is extremely sensitive to the environmental influences caused by extreme temperatures and aggressive media.
  • the functionality of the membrane can be impaired, for example, by reducing the elasticity at low temperatures and thereby the breathing resistance and the sensitivity is adversely affected or the membrane material of aggressive gases such as hydrogen sulfide or phosgene, penetrated, destroyed or at least impaired in its mechanical properties.
  • the invention is therefore based on the object, an A temschutzmnaske of the type mentioned in such a way that the function of the control diaphragm is not affected by temperature influences and aggressive media and a long life is guaranteed.
  • the basic idea of the invention consists in the arrangement of an air outlet of the exhalation valve and the control membrane together cross-cap which has at the opposite, that is, remote from the air outlet side, air outlet openings.
  • a flushing chamber or flushing channel is created above the control membrane, flows uniformly tempered, clean exhaled air of the mask wearer from the air outlet of the respirator over the surface of the control diaphragm to the air outlet opening in the cap and thereby flushes away the aggressive gases and at the same time the control diaphragm on a constant Temperature keeps or cools or heats according to the outside temperature. This ensures undisturbed functionality and a long service life of the control diaphragm.
  • the mask body 1 of a respirator has an automatic regulator 2 for supplying the air provided by a compressed air reservoir via a pressure reducer and a medium pressure line 3 to the mask wearer.
  • the control of the air supply according to the respiratory rhythm via an actuated by inhalation control membrane 4, which is connected via a lever system with a control valve (not shown) for releasing the medium-pressure line 3 during inhalation.
  • inhalation control membrane 4 which is connected via a lever system with a control valve (not shown) for releasing the medium-pressure line 3 during inhalation.
  • dashed line arrows A, B and C show the path of the inhaled air from the medium pressure line 3 via the chamber 5 and the air inlet 6 of the lung machine and along the mask discs 12 to the mask wearer, while the spent air in the direction of arrows D, E and F passes through the exhalation valve 7 to the outside.
  • the exhaled air from the mask wearer but not directly into the open air, but via an air outlet 8 in the limited by a cap 9 Spülraum 10 above the control diaphragm 4. That is, at each Ausatemzyklus uniformly tempered, clean purging air , namely the exhalation air of the mask wearer, passed over the surface of the control diaphragm 4. Regardless of the outside temperature, the control diaphragm 4 is thus always uniformly tempered and thus limited in its functionality either by too high or too low outdoor temperatures: The control diaphragm 4 is neither too stiff nor too soft, but retains its predetermined mechanical properties. The breathing conditions for the mask wearer thus remain optimal even under extreme conditions.
