REGULATED HYDRAULIC PULSER Russian patent published in 2015 - IPC F04F7/02 F04D13/04 F03B13/00 

FIELD: machine building.

SUBSTANCE: invention is related to hydraulic machine building in terms of renewable power sources. A hydraulic pulser comprises a feed line 1, a guide vane 2 with blades 3 forming centripetal drain channels, blades set above the said channels and forming centripetal pressure channels 6, and an impeller 8 with blades 10 forming drain and pressure centripetal channels 11 and 14 of a hydroturbine stage of the impeller, the channels 11 lead out to the draft tube 26 with the radial blades of centrifugal pressure pump impeller stage being set above the channels 14. The output diameters of the impeller blades in the centrifugal pump stage are less than the outer diameters of the impeller blades in centripetal hydroturbine stage.

EFFECT: invention is aimed at the provision of design output parameters and possibility to regulate the supply and head of fluid at the hydraulic pulser output.
