Abstract: A shock absorber has a main piston and a compression piston, connected by a compression piston housing. In stage 1, the shock absorber operates as a conventional monotube, with the damping force being generated only by the main piston. In stage 2, the compression piston travels into the compression housing, as the shock absorber still operates as a monotube damper. In stage 3, the compression piston is now significantly increasing its compression damping force by supplementing the main piston. The oil volume in the compression piston housing passes through the compression piston, causing an increase in compression damping force.
