A gas spring is described, comprising cylinder means (104), and a piston rod (108) slidably mounted within the cylinder means (104) and carrying a piston (106, 106') which divides the cylinder means (104) into a first working chamber (134) containing the piston rod and a second working chamber (136). Rod limit means (150, 106') are mechanically coupled to and movable with the piston rod (108) and cylinder limit means (126, 160) located within the first chamber (134) are mechanically coupled to the cylinder means (104). The limit of maximum extension of the piston rod (108) out of the cylinder means (104) is provided by contact between the rod limit means (150, 106') and the cylinder limit means (126, 160), the rod limit means (150, 106') and/or the cylinder limit means (126, 160) being axially moveable to adjust the limit of maximum extension of the piston rod (108). |
