    Abstract: System for converting mechanical energy such as ocean power into fluid power which is directed to energy conversion systems or other purposes. Included are fluid inflatable containers arranged to receive mechanical energy from a plunger mounted on a shaft, such that the flexible wall of the container forms a rolling lobe in response to changes in volume, enclosed within a drum, said shaft running axially through the drum and coupled to the drum by bearings so that the drum and shaft may move in relation to one another, a vane runs longitudinally on the drum and extending radially from an attachment point at the inner surface of the drum to the surface of the shaft. The mechanical energy is connected directly or indirectly to either the shaft or to the drum. Mechanical forces cause the plunger to press into the fluid inflatable container expelling fluid and creating fluid flow.
