Hydraulic dampers are used as travel limits in order to facilitate the closing of a sliding door, thanks to the braking effect which derives from the passing of oil through holes and slots made in the cylinder body
Through an adjustment system the braking level can be increased or decreased by opening or closing the oil passages through the piston. The stem of the shock absorber, once compressed, rearms automatically for a new cycle

Adjustment of the decelerating effect through rotation of the stem

Safety valve to discharge the braking fluid in the event of a fire and to prevent spontaneous rearming of the stem due to thermal expansion of the fluid

Steel cylindrical body, diameter 28mm

Magnet for automatic rearming, diameter 28mm
