Abstract: A damper assembly includes a tubular member, an outer cylinder positioned at least partially within the tubular member, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, a plunger received within the inner cylinder and coupled to an end of a rod extending at least partially within the inner cylinder, an annular piston fixed to the inner cylinder where the annular piston extends between the inner cylinder and the outer cylinder, and a barrier extending between the inner cylinder and the outer cylinder. The rod has an outer diameter that is smaller than an inner diameter of the inner cylinder. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The barrier, the annular piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

Abstract: A damper assembly includes an outer cylinder, an inner cylinder, a plunger, a passage, and a piston. The inner cylinder is positioned at least partially within the outer cylinder and has a cap attached to one end thereof. The plunger is positioned radially inward from the inner cylinder and coupled to a rod. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The passage extends through the rod and is fluidly coupled with the first chamber. The piston is coupled to the inner cylinder and extends radially outward toward the outer cylinder. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber. The plunger is configured to move relative to the inner cylinder, and the piston is configured to move relative to the outer cylinder.

The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The suspension system further includes a passage extending through the rod and fluidly coupled with the first chamber, a piston coupled to the inner cylinder and extending radially outward toward the outer cylinder, a first port in fluid communication with the plunger through the passage, and a second port in fluid communication with the piston. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

Abstract: A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a plunger positioned at least partially within the inner cylinder and coupled to a rod, an aperture extending through the rod, an annular piston coupled to the inner cylinder, and a valve assembly. The rod is positioned at least partially within the inner cylinder and has an outer dimension that is smaller than an inner dimension of the inner cylinder. The plunger and an interior of the inner cylinder at least partially define a first chamber. The valve assembly is in fluid communication with the first chamber and a second chamber. The annular piston extends between the inner cylinder and the outer cylinder, and the annular piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define the second chamber.
