Art. 65000 - Short hydraulic shock absorber

Hydraulic shock absorbers are used as end stops to slow the impact and facilitate the closing of sliding doors. This is possible thanks to the braking effect resulting from the passage of oil through holes and slots in the cylindrical body of the damper. By means of certain adjustments, it is possible to increase or decrease the degree of braking. Once compressed, the damper stem will automatically reset itself the first time the door is opened by means of a special magnet, preparing for a new cycle.

This damper has a safety valve which, in the event of a fire, is ready to release a braking liquid to prevent spontaneous re-setting of the stem due to the thermal expansion of the liquid, which would cause the door to reopen involuntarily and the rooms to not be compartmentalised.
