Definitions

  • the stream of air from inlet 64 is directed to diaphragm 18, increasing the pressure on the air inlet side of the diaphragm, or counteracting the suction due to inhalation, and thereby requiring a greater inhalation effort or demand by the user to open air inlet valve 32.
  • the most desirable position of the injector tube 62 for most users is the third position, in which the air stream is directed toward neither mouthpiece tube 12 nor diaphragm 18, and a normal demand or inhalation effort is required to open air inlet valve 32.
  • adjustment of the injector tube can be made by turning knob 68 to rotate the injector tube 62 with outlet 66 increasingly directed toward the diaphragm 18 to increase the pressure in the regulator to offset the increased ambient pressure on the opposite or outwardly facing side of the diaphragm.
  • the knob can be rotated in the opposite direction to approach or reach the position illustrated in FIG. 1.
