HYDROJET DEVICE Russian patent published in 2008 - IPC F03B13/14 B63B39/08 

FIELD: motors and pumps.

SUBSTANCE: invention relates to devices for wave energy conversion including vessels swinging energy to hydrojet energy. Device includes water conduit in the shape of chambers (C), which are symmetrical with regard to longitudinal axis of device. Chambers are provided with water intake inlets (I) and curvilinear walls, which are horizontal in cross-section. Walls constrict to nozzles with outlets I. Device includes one central C, two external C and no less than two internal chambers C. All chambers C are rectangular in cross-section. Vertical walls of chambers C are formed by flat horizontal plates (P). Horizontal in cross section C walls C are formed by curvilinear in longitudinal section plates P. Inlets I of external chambers C are located along horizontal walls of rectangular plates P forming vertical walls C. They are directed opposite to each other. Inlets I of internal chambers C are situated at an angle to water conduit longitudinal axis and form obtuse angle together with inlets I of external chambers C in vertical longitudinal cross section. The inlet I of the central C is situated vertically and perpendicular to longitudinal axis and along vertical walls of plant rectangular plates P forming vertical walls of water conduit. The external wall of the external chamber C is made concave with regard to longitudinal axis of water conduit. Curvilinear walls of internal chambers C, which are common with external chamber C consist of smoothly bent plates P with convex section regarding longitudinal section from the side of inlet I and with convex section regarding outlet nozzle I. Two concave curvilinear plates are installed at the inlet part of the central chamber and are symmetrical with regard to longitudinal axis. Curvilinear plate P, which is convex regarding longitudinal axis, is installed at the inlet part of each internal chamber.

EFFECT: improvement of wave energy conversion into hydrojet thrust energy.
