ORIFICE DISC FOR REGULATING FLOW IN DAMPER

摘要

A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber. A piston disposed within the fluid chamber divides the fluid chamber into an upper working chamber and a lower working chamber. The piston defines a compression passage and a rebound passage which extend through the piston between the upper working chamber and the lower working chamber. A valve disc assembly engages the piston and controls the flow of fluid between the upper working chamber and the lower working chamber. The valve disc assembly includes a bleed disc that defines an orifice with a substantially non-linear contour. The orifice extends to an outer diameter of the bleed disc, and forms a bleed channel between the upper working chamber and the lower working chamber.

1. A shock absorber for a vehicle comprising:
a pressure tube defining a fluid chamber; a piston disposed within the fluid chamber, the piston dividing the fluid chamber into an upper working chamber and a lower working chamber, the piston defining a compression passage and a rebound passage, wherein the compression passage and the rebound passage extend through the piston between the upper working chamber and the lower working chamber; and a valve disc assembly engaging the piston and controlling the flow of fluid between the upper working chamber and the lower working chamber, wherein the valve disc assembly includes a bleed disc that defines an orifice with a substantially non-linear contour that extends to an outer diameter of the bleed disc, the orifice of the bleed disc forms a bleed channel between the upper working chamber and the lower working chamber.
