Abstract

A gas spring arrangement in which conductive terminals on the cylinder and piston rod of a gas spring are connected by a conductive path insulated from the cylinder and piston rod. The path may be provided in part by contact elements on the cylinder and piston rod outside the cylinder cavity which engage each other when the piston rod approaches its axially terminal position during inward movement into the cavity. The path may also be provided in part by an insulated conductor helically wound on the piston rod in the cavity or outside. It may also include an axially elongated conductor secured to the axial cylinder wall outside the cavity.
