HYDRAULIC RAM Russian patent published in 2016 - IPC F04F7/02 

FIELD: pump engineering.

SUBSTANCE: invention relates to pump engineering, in particular to hydraulic ram engineering. Hydraulic ram comprises supplying pipeline 31, air chamber 32 with delivery pipeline 44, impact and delivery valves 16 and 43 and pressure tank 45. Ram is provided with a float chamber 22 arranged in storage chamber 4. Chamber 4 is equipped with float 14 which rod 20 is hinged at lever 13 divided into two unequal parts. One end of lever 13 is pivotally connected to edge of chamber 4, and the other end is pivotally connected via rod 7 with shutoff member 5 to L-shaped lever 6 of inlet fitting 3. Middle part of lever 13 is hinged to rod 21 connected with shutoff member 18 with L-shaped lever 19 of pipeline 31, and is connected with valve 16 of flexible drive 22. Valve 16 is made in the form of drop, located at the end of pipeline 31 with possibility of axial movement by means of guide rod 15 arranged in cylinder 30 of guides below pipeline 31 and attached to drive 22 via roller 29. End of rod 15 is installed in side wall of pipeline 31.

EFFECT: invention provides control of operation, increased efficiency and reliability, reduced specific metal consumption and faster operation.
