hydraulic damper cylinder

A hydraulic damper has an oil lock mechanism for preventing bottoming when the hydraulic damper is fully compressed. The hydraulic damper also includes an outer tube, an inner tube, a cylinder movable with the inner tube, a piston rod movable with the outer tube, a piston fixed to a distal end of the piston rod, and a coil spring disposed in the inner tube. The oil lock mechanism comprises an oil lock piece mounted on an upper end of the cylinder, and an oil lock tube disposed concentrically between the cylinder and the inner tube and having a larger-diameter portion which can be spaced from the oil lock piece when the hydraulic damper is extended and a smaller-diameter portion which can be held in sliding contact with the oil lock piece when the hydraulic damper is compressed.
