HYDRODYNAMIC MACHINE WITH TWO OR MORE IMPELLERS WITH CONTROLLED BLADES Russian patent published in 2016 - IPC F03B17/06 

FIELD: machine building.

SUBSTANCE: invention relates to hydrodynamic machine with two or more impellers. Machine includes housing (2), at least two impellers (3, 4), at least two blades (6) installed with possibility of rotation, uniformly located along impellers (3, 4) circumference, which axes are parallel to impeller axis. Each blade (6) axis is connected with guide (22, 23), which moves relative to impeller (4) shaft by means of parallelogram located in plane perpendicular to blade axis, which has lever rigidly coupled with blade axis. Second parallelogram lever is hinged on impeller lower part, while its other end is connected to first lever end. Lever, rotating on impeller lower part, is desmodromically connected to slider, integrated into guide. Slider-guide system participates in rotation, thus allowing to set harmonic motion to appropriate blade according to curve sinusoid, which axis coincides with impeller main circumference.

EFFECT: invention is aimed at creation of compact and simple hydrodynamic machine.
