Abstract

A diaphragm assembly for the diaphragm pump of an inhaling apparatus compressor contains a flexible diaphragm 1,21 with a first opening 2, 22, a lower diaphragm disc 6, 26, with a second opening 8, 28, and an upper diaphragm disc 14, 38 with a third opening 16, 40, said diaphragm discs 6, 14, 26, 38 having a smaller diameter than the flexible diaphragm 1, 21, and a securement member 18, 44, for clamping the diaphragms 1, 21, between the lower diaphragm discs 6, 26 and the upper diaphragm discs 14, 38, said securement member 18, 44 being guided through the first, second and third opening 2, 12, 16, 22, 28, 40 and being in engagement with a diaphragm drive device. For the improvement of the operational behavior and production ability, it is proposed that on the outer periphery of the flexible diaphragms 1, 21, a strip-shaped portion 4, 24 be bent towards the axis of the securement member 18, 44 and along the upper rim of the second opening 8, 28 a stop member 10, 30, be formed, against which the inside rim of the first opening of the flexible diaphragm 1, 21 can abut.
