Abstract: A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, and a plunger 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 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, the cap, and the inner cylinder through the passage, and a second port in fluid communication with the piston, the inner cylinder, and the outer cylinder. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

Abstract: This invention is a bidirectional hydraulic actuator comprising a piston assembly positioned within a housing. The piston assembly is configured to move linearly within the housing. A gland is operatively connected to the piston assembly. The gland is configured as a rigid longitudinally annular member with a first end, a second end, a sidewall and is open on the first end and substantially closed on the second end which forms an inside and an outside of the annular member. The gland is further configured with a lip extending from around the outside of the first end of the gland. A pressurizing fluid exerts pressure on the inside of the gland to move the piston assembly a first direction, then, a fluid exerts pressure on the outside of the gland and the lip of the gland to move the piston assembly opposite the first direction.
