Damper assembly
First Claim
1. A damper assembly, comprising:
- an outer cylinder;
an inner cylinder positioned at least partially within the outer cylinder;
a cap coupled to the inner cylinder;
a plunger positioned at least partially within the inner cylinder and coupled to a rod, the rod positioned at least partially within the inner cylinder, the rod having an outer dimension that is smaller than an inner dimension of the inner cylinder, wherein the cap, the plunger, and an interior of the inner cylinder at least partially define a first chamber;
an aperture extending through the rod, allowing fluid to pass into and out of the first chamber;
an annular piston coupled to the inner cylinder, wherein the annular piston extends between the inner cylinder and the outer cylinder, and wherein the annular piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber; and
a valve assembly in fluid communication with the first chamber and the second chamber;
wherein the plunger is configured to move relative to the inner cylinder,wherein the annular piston is configured to move relative to the outer cylinder.

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.

7. A suspension system, comprising:
-
a first damper comprising; a first chamber defined by a first movable surface of a first plunger, wherein the first plunger is received within a first inner cylinder and is coupled to an end of a first rod extending at least partially within the first inner cylinder, the first rod having an outer diameter that is smaller than an inner diameter of the first inner cylinder; a first aperture configured to facilitate fluid flow into and out of the first chamber; a second chamber defined by a second movable surface of a first piston and fluidly decoupled from the first chamber, wherein the first piston has an annular cross-section and extends between the first inner cylinder and a first outer cylinder; and a second aperture configured to facilitate fluid flow into and out of the second chamber; a second damper comprising; a third chamber defined by a third movable surface of a second plunger; a third aperture configured to facilitate fluid flow into and out of the third chamber; a fourth chamber defined by a fourth movable surface of a second piston; and a fourth aperture configured to facilitate fluid flow into and out of the fourth chamber; a first conduit coupling the first chamber and one of the third chamber and the fourth chamber; a second conduit coupling the second chamber and the other of the third chamber and the fourth chamber; a first valve assembly in fluid communication with the first aperture and the second aperture; and a second valve assembly in fluid communication with the third aperture and the fourth aperture. - View Dependent Claims (8, 9, 10, 11, 12, 13)
