<p>PROBLEM TO BE SOLVED: To provide a moisture absorption respiratory which allows for observation of respiration of an oil-filled electrical apparatus, even if the rate of respiration is relatively small or large.SOLUTION: A moisture absorption respiratory includes a respiratory valve having suction part and an exhaust part, and a body to which the respiratory valve can be attached. The suction part has a spherical suction part float, and a suction part float receiving plate with a suction part respiration hole engaging with the suction part float. The suction part float and the suction part respiration hole constitute a check valve for introducing air into the body from the outside. The exhaust part constitutes a check valve, for delivering air from the body to the outside, of a spherical exhaust part float, an exhaust part float receiving plate with an exhaust part respiration hole engaging with the exhaust part float, the exhaust part float and the exhaust part respiration hole.</p> |
