PUMPING UNIT FOR FLUID POWER CONVERSION Russian patent published in 2011 - IPC F03B13/10 

FIELD: engines and pumps.

SUBSTANCE: proposed pumping unit comprises float 13, housing 1 with hydraulic turbine, pump fitted in said housing 1 on common shaft with hydraulic turbine vane wheel rotor 2. Said pump is rigidly coupled with said rotor. It comprises also intake pipeline arranged in housing 1 on flow side and having cross section decreasing along flow direction. Pipeline outlet section is connected to pump intake branch pipe. Aforesaid pump represents a displacement pump. Pipeline outlet section allows directing the flow along tangential line to pump suction chamber inner surface in plane perpendicular to pump axis. Float 13 represents a hollow plate coupled with housing 1 by bracket 12 and arranged at the distance from lengthwise axis of housing 1 equal to radius of hydraulic turbine rotor 2 to displace relative to axis 14.

EFFECT: higher efficiency of operation.
