A positive expulsion tank incorporates an expanding bladder in the form of a metal bellows, which is adapted to undergo elastic deformation during a product storage condition to provide for thermal cycling of a stored product, and plastic deformation, during a product expulsion operation to achieve high efficiency expulsion of product from the tank. Convolution crests of the bellows are internally reinforced by rings, whereby plastic deformation of the bellows is caused to occur primarily in the root areas during the expulsion operation. As a result, the...
In a positive expulsion tank having a tank shell defined by first and second end walls and a side wall connecting said end walls; a bellows arranged within said tank shell and cooperating therewith to define product storage and expulsion fluid chambers, said bellows having one end fixed to said tank shell and an opposite end closed by a piston head extending transversely of said side wall, said bellows having convolutions consisting of crest portions, joining side wall portions, and root portions for connecting side wall portions of adjacent convolutions...
