Abstract

The device has a spring (9) for slowing down the closing of a protection structure e.g. shutter or flood gate, and tubes (2, 7, 8) sliding between them for guiding the spring. Supports (5, 6) maintain the spring. An endless screw maintains the protection structure open, closes the protection structure or deactivates the protection structure based on needs. The spring, supports and tubes are made of 316 stainless steel.
