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

FIELD: engines and pumps.

SUBSTANCE: invention relates to pump engineering, in particular to hydraulic ram engineering. Hydraulic ram comprises closed housing 11 in form of chamber, in which there is drain pipe 2. Working sections of pipes 3 and 4 are connected to outlet vertical pipes 9 and 10 built in housing 11. Impact valves 12 and 13 are installed on pipes 9 and 10. Valves 12 and 13 are rigidly connected with rods 16 and 17 and made in form of cones with circular baffles 14 and 15. Control drive includes rods 16 and 17, levers, load-balancer arranged on a lever and handle. Load-balancer is installed with possibility of its movement on lever and change of torque of handle. Rods 16 and 17 are arranged in guide sleeves 32, 33, 34, 35 and are passed through holes 19 and 20 in cover of housing 11 with control bushings 21 and 22, said suspension valves 12 and 13. Levers are fixed to horizontal axis of rotation for turning handle for simultaneous closing of outlet holes of nozzles 9 and 10 valves 12 and 13.

EFFECT: higher efficiency, wider field of use, lower metal consumption, higher reliability and faster operation.
