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

FIELD: machine engineering.

SUBSTANCE: ram comprises a feeding pipeline 1 with a working chamber 2 which is a continuation thereof, first impact and delivery valves 8 and 27, an air cap 26 with a delivery pipeline 28, an air intake 5 and an outlet branch pipe 10. The ram is provided with a second impact valve 15 and an adjustable water-filling container 11. The chamber 2 is designed as a water distribution unit consisting of a gas-liquid ejector 4, which active nozzle 3 is connected to the pipeline 1. The air intake 5 with a return valve 6 is installed above the ejector 4 and is communicated with the chamber 2. The chamber 2 is connected through a diffuser 24 to the branch pipe 10. The outlet of the branch pipe 10 is closed by the valve 8 connected to a float 12 located in the container 11 by articulated lever drive. The valve 15 is installed on outlet hole of an inlet branch pipe 13 and connected through a rod 22 with the articulated lever drive. The branch pipe 13 is hydraulically connected to a pressure tube 25 of the branch pipe 10 by means of an additional tank 14. The valves 8, 15 operate synchronously.

EFFECT: increase of operation efficiency, increase of reliability in operation under transient conditions and manufacturability of its production.
