ABSTRACT:
A rotary pump capable of slow movement, for wave power applications. The pump is a helix formed of tubing whereby when the helix is rotated, the inlet end of the tubing scoops water and an outlet end of the tubing directed along the central longitudinal axis of the helix delivers liquid to a conduit means. The helix of tubing is preferably mounted on a shaft which is turned by ratchet device powered by rocking motion or rise and fall of water due to wave motion.
