gas compression springs
Gas pressure springs are used to balance weight and thus work against the weight force of a cover. When a cover is opened, the manual force is thus supported by the gas spring. A gas strut is an enclosed, maintenance-free element. It consists of a pressure tube and a piston rod with piston. In addition, a seal to prevent possible loss of gas is fitted at the piston rod guide. The gas spring is filled with compressed gas – nitrogen – which provides the spring force.
