HYDRAULIC RAM Russian patent published in 2017 - IPC F04F7/02 

FIELD: machine engineering.

SUBSTANCE: hydraulic ram comprises a feeding pipeline 1 with an adjustment tank 2 which is a continuation thereof, first impact 15 and delivery valves 30, an air cap 31 with a delivery pipeline 32, a tank 12 with a discharge pipeline 11. The valve 30 has a seat 29 above the pipeline 1. The tank 12 is connected to two outlets 13 and 14 connected to the pipeline 11. The ram is provided with a second impact valve 16 formed by a segment shield mounted on a dispensing opening of the upper water outlet 14. The valve 15 is formed by a shield gate mounted on the flow opening of the lower water outlet 13. There is a three-link hinged-lever mechanism above the water outlet 14 connected by means of rods 22 and 23 to the segment shield mounted on an axle 19 and the shield gate mounted on rotation axis 17.

EFFECT: reduction of hydraulic resistances in the hydraulic drive, increase of speed and reliability in operation in transient modes and manufacturability of its production.
