Abstract (en)
[origin: WO2020178529A1] The invention relates to a diving mask comprising a snorkel (4) with a valve (34), the valve (34) comprising: - a valve port (38) intended to allow fluid, in particular air, to circulate between the outside of the snorkel and the inside of the snorkel, and - a valve shutter element (40), for example a float, which can be moved between an open position in which the valve port (38) is open and a closed position in which the valve port (38) is closed by the valve shutter element (40), the mask also comprising a balancing means (46) for restricting a pressure difference between the inner pressure of the mask and the outer pressure, the balancing means (46) being configured to allow fluid to circulate between the outside of the mask and the inside of the mask when the mask is being worn by a user and the shutter element (40) is in the closed position.
