Scupper valve snorkel
A conjoined tube within a tube located inside a lower section of a snorkel designed to steer water droplets away from the snorkel diver's breathing path. The lower section of the snorkel has two valves. One is the scupper valve positioned at the lowest point of the inside tube. The scupper valve is a light duty valve or a low resistance one-way watertight passage intended to allow droplets of water to drain into the main reservoir. The outer tube lower section contains a reservoir for holding residual water that travels down to the bottom of the snorkel and is contained therein. During the normal clearing operation, the reservoir can be emptied and water will exit out of the lower section and into the surrounding water.
1. In a snorkel used for breathing through a mouthpiece beneath the surface of a body of water and having a conduit with an opened top extending above the mouthpiece, a mouthpiece section for reducing accumulation of water in the mouthpiece from droplets falling along the interior surface of the conduit toward the mouthpiece, the mouthpiece section comprising:
an outer tube and an inner tube extending co-axially within said outer tube; and
a mouthpiece tube connecting said mouthpiece to said inner tube through a radial portion of said outer tube;
a radial gap between said inner tube and said outer tube, said gap being configured to provide capillary action to promote the transfer of water droplets between said inner and outer tubes and away from said mouthpiece;
said inner tube terminating below said mouthpiece tube in a one-way valve for permitting accumulated water in said inner tube to exit into said outer tube;
said outer tube extending below said inner tube to form a water reservoir below said inner tube; and
said outer tube water reservoir having a one-way valve for purging water from said reservoir out of said outer tube.
2. The mouthpiece section recited in claim 1 , said inner tube terminating in a one-way valve for permitting accumulated water in said inner tube to exit into said water reservoir.
3. The mouthpiece section recited in claim 2 , the one-way valve of said outer tube and the one-way valve of said inner tube, being in spaced co-axial relation.
4. A snorkel comprising:
a conduit terminating at one end in an open top for extending above the surface of a body of water and having a second end terminating at a mouthpiece section permitting breathing through said conduit even while said mouthpiece section is beneath said surface;
said mouthpiece section being configured for reducing the accumulation of water from droplets falling along the interior surface of said conduit, said mouthpiece section having an outer tube and an inner tube, the inner tube residing co-axially within said outer tube and spaced therefrom to form a radial gap therebetween; and
a mouthpiece extending radially from said outer tube and being connected by a mouthpiece tube to said inner tube;
said radial gap being configured to provide capillary action to promote the transfer of said droplets between said inner and outer tubes and away from said mouthpiece;
said inner tube terminating below said mouthpiece tube in a one-way valve for permitting accumulated water in said inner tube to exit into said outer tube;
said outer tube extending below said inner tube to form a water reservoir below said inner tube; and
said outer tube water reservoir having a one-way valve for purging water from said reservoir out of said outer tube.
5. The mouthpiece section recited in claim 4 , said inner tube terminating in a one-way valve for permitting accumulated water in said inner tube to exit into said water reservoir.
6. The mouthpiece section recited in claim 5 , the one-way valve of said outer tube and the one-way valve of said inner tube, being in spaced co-axial relation.
