Abstract

An improvement on the subject of main patent number 408,936 which rests with an oil pressure tank, comprising an oil pressure receiving container containing a stack of gas-filled cells, each cell comprising two generally parallel plates each formed with a plurality of concentric annular corrugations, the cells being arranged with respect to said adjacent cell plates in face-to-face contact, each of said plates of each cell having the tops of their corrugations aligned with the tops of the plate corrugations of the adjacent cell with which it is in contact, and at least one plate of each pair of plates in contact having at least the tops of certain corrugations varying in height around the circumference thereof, such being the arrangement that, in the case of evacuation of the container, the movement in direction of each other of each pair of plates in contact is limited by the contact of the pair of plates in the portions of the highest tops of said certain corrugations, while at least there is a generally radial passage that extends between each pair of plates in contact, from the periphery of the cells to the axes of the pile, above the lower portions of said certain corrugations.
