The tip of the air supply hose for breathing extended from an air cylinder etc. is attached to hose Take 1.104 of Pulmonic valve. Lamina tecti 17 which has closed operation pressure adjustment hole 115 of protection plate 13 oppresses random vibration of the pressure-taking diaphragm at the time of a valve action, and prevents generating of an unpleasant noise, and it has the operation which prevents operating pilot valve element 113 indiscriminately. Valve box board 7 and valve room plastic surgery board 9 may be fabricated to one depending on the shape of a valve room. Hereinafter, the operation is explained. If the pressure in a face piece declines by a wearing person's air intake operation during use of a mask, It falls in the pressure of pressure-taking room 133 which is open for free passage by small vent 127, and pilot valve element 113 of pressure-taking diaphragm 12 separates from the mouth of pilot nozzle 99, and flows into the pressure air or the exhaust room in operation room 83, and the pressure in operation room 83 declines. Diaphragm valve board 10 separates from a valve seat, and the air for breathing flows in a face piece through valve room 49 and three air supply passages 131 due to the decreased pressure from a valve port/16. By expiration operation of the wearing person who follows an air intake, if it Rising 1 11 in the pressure in a face piece, the pressure of pressure-taking room 133 will also rise and carry out, and pressure-taking diaphragm 12 will close pilot nozzle 99 of an operation room. Then, Luke of operation interior of a room 83 who has received supply of a fixed quantity of pressurization air continuously through needle valve 102 Soil brother, diaphragm valve board 10 closes tPO, and the inflow of Air supply into valve room 49 and supply of the air for breathing into a Sad straw face piece are stopped. During the use, Intrapulmonary valve repeats the above-mentioned operation and supplies the mask wearing person l\ necessary gas for breathing. As mentioned above, although the example which applied this design to Intrapulmonary valve was described, this design is a pressure corresponding movement diaphragm valve board rum valve of various uses. To -- it is natural. moreover -- looking this design like [ the range of the utility model registration dh Request ] variously by written within the limits, and carrying out change Shogo -- operation Be able to.

[Effect of the Device] this design -- getting twisted -- pressure-taking diaphragm 12 -- the pilot nozzle of an operation room -- direct -- opening-and-closing 4' To -- it can write like, can compare with a publicly known thing (JP,58-133363,U) conventionally, and can shorten considerably the direction length of an axis of a pressure corresponding movement Di A * Fulham valve. According to this design, it can do [ reducing sharply a cost of production to assemble a valve subject and to be made or ] by making all the parts by die forming, and only carrying out the lamination Sushi bundle of them without cutting. Since the hose for Air supply is automatically stuck to the valve seat in Removed and diaphragm valve board 10 from the hose attachment mouth and a valve port is closed when this design is applied to Intrapulmonary valve, by publicly known Intrapulmonary valve, needed nonreturn A r can be conventionally made unnecessary.
