Abstract
A damper assembly includes an outer cylinder, an inner cylinder, a cap, a plunger, an annular piston, and a barrier. The inner cylinder is at least partially positioned within the outer cylinder. The cap is coupled to the inner cylinder, and the plunger is received within the inner cylinder. At least a portion of the annular piston and the barrier extend between the inner and outer cylinders. During operation of the damper assembly, the plunger moves relative to the inner cylinder and the annular piston moves relative to the outer cylinder.

A damper assembly, comprising:
- an outer cylinder;
- an inner cylinder at least partially positioned within the outer cylinder;
- a cap coupled to the inner cylinder;
- a plunger received within the inner cylinder,
- an annular piston, wherein at least a portion of the annular piston extends between the inner and outer cylinders;
- a barrier extending between the inner and outer cylinders,
- wherein the plunger moves relative to the inner cylinder, and
- wherein the annular piston moves relative to the outer cylinder.
A damper assembly, comprising:
- an outer cylinder;
- an inner cylinder at least partially positioned within the outer cylinder;
- a cap coupled to the inner cylinder;
- a plunger received within the inner cylinder;
- an annular piston fixed to the inner cylinder, wherein the annular piston extends between the inner and outer cylinders;
- a barrier extending between the inner and outer cylinders,
- wherein the plunger moves relative to the inner cylinder, and
- wherein the annular piston moves relative to the outer cylinder.
A suspension system, comprising:
- a first damper comprising:
- a first chamber having a first movable surface for changing the volume of the first chamber, and
- a second chamber having a second movable surface for changing the volume of the second chamber;
- a second damper comprising:
- a third chamber having a third movable surface for changing the volume of the third chamber, and
- a fourth chamber having a fourth movable surface for changing the volume of the fourth chamber;
- a first conduit coupling the first chamber and one of the third and fourth chambers;
- a second conduit coupling the second chamber and the other of the third and fourth chambers,
- wherein the cross-sectional areas of the first, second, third, and fourth movable surfaces are substantially equal to each other.
