Abstract

The Damping Gas Spring configuration (100) that comprises the piston (104) that provides bearing and sealing, the Damping Gas Spring's Tube (106) that functions as the external protective pressure chamber, the Damping Gas Spring rod (101) that moves inside said Damping Gas Spring's Tube (106) and where the piston (104) is connected to the end, the bearing component (107) that enables bearing of the Damping Gas Spring rod (101), the o-ring (102) that surrounds the inner periphery of the Damping Gas Spring's Tube (106) depending on the direction of operation and that allows or blocks the passage of air by moving bidirectionally, the return groove (103.1) that functions as a passageway for air by opening motion of the o-ring (102) while the Damping Gas Spring configuration (100) is closing, the sealing component (108) that compresses the gas inside the Damping Gas Spring's Tube (106) and that prevents it from leaving the cylinder, wherein comprising; the speed hole (101.1) that enables passage of air by being machined on the Damping Gas Spring piston (101) and that adjusts the opening speed of the Damping Gas Spring configuration (100) through the diameter of the machined hole, the rod-integrated channel (101.2) that enables passage of air coming from the said speed hole (101.1) to the other side of the piston (104) and that is machined inside the Damping Gas Spring rod (101), the braking component (105) that is stationary in the Damping Gas Spring's Tube (106) and that enables regulation of speed by gradually closing the speed hole (101.1) while the Damping Gas Spring configuration (100) is being opened by allowing the Damping Gas Spring rod (101) to pass through itself.
