ABSTRACT:
A snorkel for swimmers, having a basic concept of hydraulic bladders connected by tubes which block or open a blow hole of the snorkel tube; the bladder being under constant pressure from its own elastic walls collapsing when pressure from a jaw or tongue on the bladder is released by the separation of the teeth or drawing back of the tongue, thus opening the air tube, allowing inflow of air normal inhalation of the lungs.
