Abstract
A hydraulic damper comprises an outer cylinder, and an inner cylinder slidably mounted within the outer cylinder for movement relative to the outer cylinder along a longitudinal axis. The inner cylinder has a circumferential wall circumscribing a bellows assembly. The bellows assembly comprises a first bellows section, a second bellows section, a damping plate attached to and separating the first and second bellows sections, a first closure element closing an end of the first bellows section opposite the damping plate to define a first chamber, and a second closure element closing an end of the second bellows section opposite the damping plate to define a second chamber. The first closure element is attached to the inner cylinder for movement therewith relative to the outer cylinder. The second closure element is also attached to the inner cylinder for movement therewith relative to the outer cylinder.
