Abstract
A hydraulic damper including a tube. A piston assembly is disposed slidably inside the tube and divides the tube into a rebound chamber and a compression chamber. A fluid compensation chamber is located outside of the tube. A base valve assembly controls the flow of the fluid between the compression and compensation chambers. A hydro-mechanical compression stop assembly includes a covering member that overlies the base valve assembly and defines a main flow channel and an auxiliary flow channel that each fluidly connect the compression chamber and the base valve assembly. A closing member selectively closes the main flow channel. A first telescoping sleeve is coupled with the piston assembly and a second telescoping sleeve has a base connected to the closing member. A first spring is compressed between the piston assembly and the base to bias the closing member in an extended position.
