Abstract: A damper assembly includes a rod elongated along an axis. The damper assembly includes a body supported by the rod, the body having a first surface and a second surface opposite the first surface. The body and the rod define a passage between the body and the rod, the passage extending from the first surface of the body to the second surface of the body.

Abstract: A damper assembly includes a pressure tube defining a first chamber and a piston movable within the first chamber. The damper assembly includes a reserve tube defining a second chamber. The damper assembly includes a cylinder end attached to the pressure tube, the cylinder end defining a passage in fluid communication with the first chamber and the second chamber. The damper assembly includes an orifice disc attached to the cylinder end and defining an opening in fluid communication with the passage. The damper assembly includes a check disc attached to the cylinder end, the check disc movable from a first position spaced from orifice disc to a second position abutting the orifice disc. Movement of the piston within the first chamber causes fluid flow between the first chamber and the second chamber via the passage of the cylinder end. The check disc and the orifice disc limit a rate of such fluid flow.

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.

Abstract: A damper assembly includes a cylinder defining a chamber. The damper assembly includes a body supported by the cylinder and having a first surface and a second surface opposite the first surface. The body defines a passage extending from the first surface to the second surface. One of the first surface or the second surface define a slope at the passage. The damper assembly includes a check disc at the slope, the check disc selectively restricting fluid flow through the passage.
