Abstract: A hydraulic vibration damper includes a housing assembly and a rod assembly. The housing assembly includes a main housing, an end cap and a rebound cut off (RCO) assembly. The rod assembly includes a hollow piston rod coupled to a main piston assembly. The main piston assembly includes a main piston that is displaced along the main housing between extension and compression directions. The RCO assembly is disposed between the main housing and the hollow piston rod and includes an RCO piston and an RCO flask. The RCO flask has a flask body including at least one flask passage defined therein that communicates hydraulic fluid along the flask body.

Abstract: A damper with a main damper assembly includes a damper tube with a damping fluid. A main working piston divides a main fluid chamber into a piston rod side and a non-piston rod side. The main fluid chamber has an upper zone, a lower zone and a mid-zone. A secondary damper assembly with a secondary working piston is in fluid communication with the main damper assembly. When the main working piston travels in the mid-zone, fluid is caused to pass through the main working piston and the secondary working piston to generate a first damping force and when the main working piston travels in either of the upper and lower zone, fluid is caused to pass only through the main working piston to generate a second damping force, wherein the first damping force is less than the second damping force.
