Abstract

PURPOSE: To reduce the dead volume of the top part of a gas bag, by making the gas bag of a flexible hermetic material in the form of a vertical pyramid and enabling the vertical motion of the gas bag under constant pressure.
CONSTITUTION: The rear ends of hanger ropes 4 are symmetrically secured on the top of a rigid plate 1' of the ceiling part of a gas bag. The ropes 4 extend on guide pulleys 6, 6' attached to the ceiling 11 of a house. Balancing weights 5 corresponding to the total weight of the gas bag, the rigid plate 1', a peripheral plate 1", etc. are coupled to the front ends of the ropes so that a ceiling diaphragm 1 is vertically moved as it extends horizontally. The gas bag is made of a flexible hermtic material. The cross section of the peripheral wall of the gas bag is shaped into saw teeth. The horizontal cross-sectional area of the gas bag is increased from the top of the bag toward its bottom. As a result, the gas bag is vertically moved under constant pressure and the dead volume of the top part of the gas bag is reduced.
