A system for enabling fluid flow is provided which includes a plurality o f frusto-conical elements, central and outer spherical shells which enclose the frusto-conical elements, constraining means which constrain the elements between the central and outer spherical shells, and input and output means for allowing fluid flow into and out of the system. The geometry of the frus to- conical elements and their alignment within the system allows the format ion of chambers between adjacent elements and their central and outer shells . The elements are free to roll about one another within the system in a syn chronized manner. This synchronized rolling is results in a cyclical change in volume of those chambers.
