ABSTRACT:
Aneroid bellows assembly utilized in the emergency oxygen supply systems of aircraft includes a leaf spring mounted at its center to an adjustably positioned end fitting located on the axis of an evacuated bellows spring. The outer edges of the leaf spring are engaged with an adjustable ring threadedly mounted on the outer rim of a tubular housing member in which the bellows spring is mounted. The adjustable end fitting and ring permit elements having a substantial size tolerance to be assembled together and readily adjusted to achieve precise calibration.
