Breathing equipment for providing protection against drowning, in particular for the driver of a motorized water vessel

摘要

Equipment for providing protection against drowning, in particular for use by the driver of a motorized water vessel, the equipment comprising:PPa supply (110) of air under pressure, feeding a regulating pressure expander (130, 140);P Pa face mask (210) including a breathe-in valve (211) and a breathe- out valve (212); andPPswitch means (160) for selectively connecting the breathe-in valve of the face mask either to the regulating pressure expander or else to the atmopshere, said switch means being constituted by an electrically controlled valve permanently powered via a safety inertia switch, such that the breathe-in valve of the face mask is connected to the surrounding air so long as the electrically controlled valve is fed with electricity, and that in the event of the inertia switch interrupting the supply of electricity to the electricity controlled valve, because of the vessel being subjected to a shock, the breathe-in valve of the face mask is immediately switched to the regulating pressure expander.
