Abstract
A liquid expulsion apparatus 12 having a rolling diaphragm 20 conforming to the non-circular shape of the storage tank shelf 30, thereby increasing liquid storage capacity within the tank. A gas-driven piston 24, also conforming to the non-circular shape, expels the liquid in rapid fashion and provides the force for rolling the attached non-circular diaphragm 20. Stability in diaphragm 20 during actuation of piston 24 is maintained by varying the local thicknesses t of diaphragm 20 in relationship with the local, cross-sectional radii of curvature R.sub.c.
