Regulator for Underwater Breathing Apparatus

Abstract

Regulator for underwater breathing apparatus, comprising a box-like body in which is formed a chamber having a first tubular element for connection to a mouthpiece, a second tubular element provided with a regulating valve for supplying air to the inside of the regulator chamber, a conduit for discharging expired air and any residual water, and an aperture on which is positioned a flexible diaphragm surmounted by a cover provided with a set of holes or apertures adapted to allow water to come into contact with the outer surface of the flexible diaphragm; the flexible diaphragm interacts by suitable means with the regulating valve; the diaphragm and the cover lie on, or are parallel to, a plane (M′) facing upwards and inclined forwards relative to a generally upright position of the diver; a plurality of water inlet apertures is formed behind the cover.

1 . Regulator for underwater breathing apparatus, comprising a box-like body in which is formed a chamber having a first tubular element for connection to a mouthpiece, a second tubular element provided with a regulating valve for supplying air to the inside of the regulator chamber, a conduit for discharging expired air and any residual water, and an aperture on which is positioned a flexible diaphragm surmounted by a cover provided with a set of holes or apertures adapted to allow water to come into contact with the outer surface of the flexible diaphragm, the flexible diaphragm interacting by suitable means with the regulating valve, characterized in that the diaphragm and the cover lie on, or are parallel to, a plane (M′) facing upwards and inclined forwards relative to a generally upright position of the diver, a plurality of water inlet apertures being formed behind the cover. 
     
     
         2 . Regulator according to  claim 1 , in which the discharge conduit is formed in the box-like body of the regulator in a lateral position relative to the tubular mouthpiece connection element. 
     
     
         3 . Regulator according to  claim 1 , in which the discharge conduit is inclined downwards relative to a generally upright position of the diver. 
     
     
         4 . Regulator according to  claim 1 , in which the discharge conduit is positioned on the side opposite the side of the box-like body in which is formed the tubular element for connection to the air supply hose. 
     
     
         5 . Regulator for underwater breathing apparatus, comprising a box-like body in which is formed a chamber having a first tubular element for connection to a mouthpiece, a second tubular element provided with a regulating valve and adapted to be connected to a hose for supplying air to the inside of the regulator chamber, a conduit for discharging expired air and any residual water, and an aperture in which is positioned a flexible diaphragm surmounted by a cover provided with a set of holes or apertures adapted to allow water to come into contact with the outer surface of the flexible diaphragm, the flexible diaphragm interacting by suitable means with the regulating valve, characterized in that the tubular element for connection to the air supply hose is inclined to the rear, in other words towards the tubular mouthpiece connection element. 
     
     
         6 . Regulator according to  claim 5 , in which the angle (C) of inclination of the tubular hose connection element is variable between 30° and 60°. 
     
     
         7 . Regulator according to  claim 5 , in which the tubular connecting element is additionally inclined upwards relative to a generally upright position of the diver. 
     
     
         8 . Regulator according to  claim 5 , in which said means comprise at least one lever interacting with the regulating valve and with the flexible membrane is made with a degree of single or double curvature so as to follow the shape of the box-like body. 
     
     
         9 . Regulator for underwater breathing apparatus, comprising a box-like body in which is formed a chamber having a first tubular element for connection to a mouthpiece, a second tubular element provided with a regulating valve for supplying air to the inside of the regulator chamber, a conduit for discharging expired air and any residual water, and an aperture on which is positioned a flexible diaphragm surmounted by a cover provided with a set of holes or apertures adapted to allow water to come into contact with the outer surface of the flexible diaphragm, the flexible diaphragm interacting by suitable means with the regulating valve, characterized in that the chamber inside the box-like body has a truncated conical shape with an increasing cross section inclined towards the conduit for discharging expired air and any residual water. 
     
     
         10 . Regulator according to  claim 9 , in which the chamber comprises two truncated conical surfaces having different inclinations, the surface with the greater inclination being positioned directly upstream of the discharge conduit.
