Fluid Pump and Expandable Energy Storage Device
Abstract
A fluid pump and expandable energy storage device includes a substantially rigid circular band, a substantially rigid central hub, a membrane fixed to the band and to the hub, the membrane being enlargeable by a fluid introduced into the device, and a plurality of rods interconnecting the band and the hub. The enlargeable membrane is adjacent the rods, such that enlargement of the membrane causes movement of the hub and portions of the rods away from a plane of the band. The movement causes twisting and bending of the rods, biasing the rods to return to their original positions upon release of the fluid. Upon such release, the membrane and the rods immediately return to their non-enlarged states, forcing the fluid out of the device at a high velocity.
