FLOW ENERGY DAMPER Russian patent published in 2013 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: damper comprises a water cushion 1, which is cone-shaped, and the upper edge 2 of which is connected to the output end of the supply pipe 3. The water cushion comprises a receiving reservoir (a jacket) 4 installed in its inner cavity and made in the form of a truncated cone, the end of which is equipped with a locking cap 5, located coaxially to the supply pipe 3. Descending parts of the cap vault are equipped with radially arranged slot cuts 6. The expanded part of the truncated cone with water outlet holes 8 has an upper edge 9 bent along the radius and connected with the upper edge 2 of the water cushion, forming a circular wall cushion with the walls. The water cushion is equipped with a drain channel 11 communicated with it and comprising a retaining structure made in the form of a curvilinear shield 12 installed hingedly on an axis 13 and comprising a canopy 14 bent downwards and submerged in the draining channel, facing towards the water cushion with the possibility of interaction between the lower edge of the canopy with a threshold 15 at the bottom of the draining channel.

EFFECT: increased reliability of structure operation by expansion of the range of efficient damping of excessive flow energy.
