Diaphragms are widely used as detectors of accumulators and manipulators of pneumaticautomatic control apparatus. The author measured the forces on diaphragms under a fluid pressure for each lift of valve, using diaphragms with several kinds of accumulators of lower and higher pressures, changing dimensions of discs and materials and sectional forms of diaphragms. As the results, for each diaphragm, the values of F/F_0 concentrate on a straight line, regardless of the change of pressure, and are proportional to lifts. (F is the force which acts on the disc and F_0 is a portion of the force that the diaphragm shares.) This tendency for the diaphragm is not changed by dimensions of the disc, but is changed by material and thickness of the diaphragm We explained the matter considering that inasmuch as the sectional forms of the diaphragms for each lift differ under a certain pressure, the directions of tensions of the diaphragm acting at boundary of the disc have an effect upon values of F/F_0.
