HYDRAULIC JET DEVICE Russian patent published in 2011 - IPC F03B13/14 F03G7/08 

FIELD: power industry.

SUBSTANCE: hydraulic jet device includes water conduit made in the form of system of channels with inlet water intake holes, which are located symmetrically relative to its longitudinal axis, vertical side walls common for all channels and with curved walls which are horizontal in cross section of channels, which form nozzles converging in the flow direction and having the outlet holes for conversion of mechanical energy of the ship's rolling to hydraulic jet energy. System contains three stages of energy conversion, which are located one after the other. Each of the stages is made in the form of system of channels located one above the other in vertical longitudinal plane of the water conduit section and symmetrically relative to its longitudinal axis. At that, water conduit of hydraulic jet device is fixed by means of torsion bars with possibility of being turned in horizontal plane relative to longitudinal axis of water conduit through an angle of 10° to 15°.

EFFECT: increasing use efficiency of hydraulic jet device at conversion of wave energy to hydraulic jet energy.
