ABSTRACT:
A transducer for converting the energy of ocean currents to the energy of a high-pressure fluid comprises a plurality of transducer units each including a sea-water channel, a plenum room overlying the channel, an impeller rotatably disposed in the channel and plenum room and rotatable by a sea-water flow through the channel, and a converter mechanism operatively coupled with the shaft of the impeller for producing a high-pressure fluid in response to revolution of the impeller. To prevent pressurized air in the plenum room for leaking out of the transducer unit when the transducer is joggled underwater as in stormy conditions, a pair of air-trapping chambers are located one on each side of the plenum room and open toward the channel for receiving any air which has escaped from the plenum room through the channel. Each chamber may contain a part-spherical air-trapping member that is pivotally movable into the channel upon inclination of the transducer so as to prevent the trapped air from leaking out of the air-trapping chamber.
