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

FIELD: machine engineering.

SUBSTANCE: hydraulic ram has a working chamber 3, 4, an air cap 7, 8 with a rod 11, 12 of discharge valve 9, 10, an elastic diaphragm, a pipeline and power supply contacts 39, 40. The elastic diaphragm is made in form of membrane impact valve 15, 16 on the end side of the chamber inner space 3, 4, is isolated from the environment by a cover 19, 20. The shaft 11, 12 is located in the cap 7, 8 with an air duct 23, 24, a cover 33, 34 which has a guide hole 21, 22 made coaxially to the valve 9, 10, which free end is located in an opening 21, 22 with possibility for opening in water supply cycle from the chamber 3, 4. The rod 11, 12 in the upper part is provided with an open movable contact with a limiter. The valve 15, 16 is made with rigid center. The chamber 3, 4 is provided with an electromagnet 17, 18 fixed to its end, with the possibility of contacting the valve 15, 16 and connected to the power supply unit 39, 40 and a normally open contact 41, 42 adapted to interact with the open movable contact of the rod 11, 12.

EFFECT: increased operation efficiency, expanded field of application, reduced material consumption, increased reliability and quick action.
