Abstract
A damper assembly includes a pressure tube forming a chamber, a piston assembly disposed in the chamber and dividing the chamber into two subchambers, and a piston rod fixed to the piston assembly. The piston assembly includes a body having an inner bore extending axially through the body. The piston assembly includes a blowoff disc contacting the body at the inner bore and having a throughhole aligned with the inner bore. The piston rod extends through and concentrically contacts the inner bore and the throughhole. The body has a groove extending axially along a length of the inner bore. The groove and the piston rod form a passageway permitting fluid to travel across the body. The blowoff disc has a notch extending from the throughhole and arranged to permit fluid from the passageway to pass across the blowoff disc.
