ABSTRACT:
In a gas-operated cylinder, the surfaces of the cylinder and piston that are in sliding contact are lubricated by an oil-impregnated wick disposed in an annular chamber at the rod end of the cylinder. The wick extends through radially inwardly extending openings in the chamber to contact the piston rod and also through axial openings in the chamber to contact the back side of the piston when the latter moves to the rod end of the cylinder.
