Abstract
A diving mask includes a transparent visor, a frame, a gasket to guarantee the watertight seal and appropriate belts for fitting the mask, a breathing tube associated with the facial part is fitted onto the upper part of the mask and which enables the flow of air to enter into the compartment between the frame and the visor. The path of air in the inhalation phase and in the exhalation phase both in the mask and tube are different from each other. The tube is made with separate ducts for inhalation and exhalation and the inside of the mask is made with two compartments, one upper front and one lower oronasal separated by a wall. The path provides that inhalation air is introduced by the tube into the frontal compartment and then into the oronasal one and air exhaled from the oronasal compartment travels up to the tube.
