Abstract
A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber and a piston disposed within the fluid chamber. The piston divides the fluid chamber into an upper working chamber and a lower working chamber, and defines a compression passage and a rebound passage. A valve disc assembly of the shock absorber engages the piston and controls the flow of fluid between the upper and lower working chambers. The valve disc assembly includes an orifice check disc and an orifice disc. The orifice disc defines a bleed passage between the upper and lower working chambers. The orifice check disc is disposed between the piston and the orifice disc. The orifice check disc closes the bleed passage as the fluid flows in a first direction and opens the bleed passage as the fluid flows in a second direction opposite of the first direction.
