ABSTRACT:
A gas spring having a cylinder and a piston rod. A piston mounted on a piston rod is provided with flexible tongue, rounded ends of which elastically bear on the inside wall of the housing while the rest of the piston is free from the housing. The flexible tongues assist in preventing partial cylindrical faces of the piston from smashing against the inside wall of the piston housing when the gas spring is vibrating.
