A humidifer for aqualung equipment comprises a source vessel housing moistening water which is or is not contained in a fibrous material member, and a water applying passage disposed to communicate the source vessel with the gas supply passage of the respirator and normally shutting off such communication, whereby when pressure in the gas supply passage is temporarily lower than that in the source vessel upon respiration of the user, such pressure difference may cause the water in the source vessel to be applied in a sprayed form from the applying passage into the gas supply passage. A further humidifier includes a water containing fibrous material member disposed directly in the gas supply passage of the respirator and kept to be in a water containing condition by supplying water through the aforementioned water applying passage.

A combined aquatic respirator and humidifier for underwater diving use with a cylinder holding an oxygen-containing, highly pressurized gas carried on the back of a diver comprising a moistening water source vessel including a body casing and a closure casing removably attached to said body casing, said closure casing having a gas inlet passage formed therein for connection with the interior of said cylinder, said body casing having an outlet passage therein, a hose member having first and second ends, said outlet passage being connected to said first end of said hose member, a moisture applying cylindrical member disposed within said moistening water source vessel and communicating at one end thereof with said outlet passage and the other end thereof with said inlet passage and having means consisting of a plurality of apertures disposed in its peripheral wall for forming therein a water film produced by aqueous surface tension when no pressure difference exists across said peripheral wall, a water-containing hydrous member encased in a space defined between the outer peripheral wall of said moisture applying cylindrical member and the inner peripheral wall of said moistening water source vessel, and a mouth-piece communicating with the second end of said hose member and adapted to be held in the mouth of a diver for inhaling gas through said hose member.
