Transducer for conversion of sea water-energy

A transducer apparatus for converting the energy of sea waves to an energy of a high pressure fluid, comprising,in combination, a rectangular casing having an interior communicating with the air, a plurality of impeller chambers disposed in spaced relationship within said casing, each of said impeller chambers including a plenum space located on the upper portion thereof, a sea-water channel located in the lower portion thereof to communicate with said plenum space, said sea-water channel having both ends opened into the exterior of said casing, an impeller disposed therein such that an upper portion thereof is located in said plenum space and the substantial portion of its lower half is located in said sea-water channel, and a rotary shaft for said impeller running slightly above and in parallel to an interface between the plenum space and the sea-water channel, said rotary shaft having both end portions extending externally of said impeller chamber, fluid compression means disposed on either side of said impeller chamber externally thereof to be operatively coupled to each end of said rotary shaft, and a U-shaped bank means having a pair of legs of the U bridged by said casing, the arrangement being such that, with said casing and said U-shaped bank means partly submerged in the sea to project the upper portions thereof above the surface of the sea, a sea water pool is formed between said casing and said U-shaped bank means to communicate with the outer sea water only through said sea-water channels and that sea waves overflowing said upper projecting portion of said bank means flow through said sea water channels to drive the associated impellers to cause said fluid compressor means to produce a high pressure fluid from the air.
