Abstract
A shock absorber damper assembly is provided that includes a working cylinder filled with fluid. A piston and rod are disposed in the working cylinder and move along an axis to provide dampening during a compression stroke. For a twin tube arrangement, a reservoir surrounds the working cylinder and may include a gas cell to accommodate the volume of the rod. A recoil valve controls flow of the fluid from the working cylinder to the reservoir during a recoil stroke. The recoil valve has an opening force controlling damping during the recoil stroke. A fluid passageway, which may be located in the reservoir, connects the working cylinder and the recoil valve. A check valve is disposed in the fluid passageway and opens to receive the fluid during the compression stroke. The check valve closes during the recoil stroke to retain the fluid against the recoil valve at a pressure and adjust the opening force of the recoil valve.
