HYDROJET DEVICE Russian patent published in 2009 - IPC F03B13/14 B63B39/08 

FIELD: engines and pumps.

SUBSTANCE: invention is related to devices for transformation of waves energy, in particular, for transformation of vessel vibration energy into hydrojet energy. Hydrojet device comprises channel-tube system, lateral right 1 and left 2 walls of device. System consists of fixed straight and profiled plates. It contains the first and second stages of energy transformation. The first stage of energy transformation includes wall 3 of central pipeline 4, wall 5 of internal channel-pipeline, internal channel - pipeline 6, external wall 7 of external channel-pipeline 8. The second stage of transformation includes wall 9 of central pipeline 10, wall 11 of internal channel-pipeline 12, internal channel- pipeline 12 and external wall 13 of external channel-pipeline 14. Central channels 4 and 10 are arranged with inlets 15. Also cutoff plates 16 are installed in channels.

EFFECT: invention makes it possible to use all energy of waves, independently on angle of flow striking at device along its longitudinal axis, which results in higher efficiency of device application during transformation of waves energy into hydrojet energy and stabilisation of vessel position.
