Abstract: A damper includes a piston coupled to a piston rod slidably positioned in a damper tube. A piston rod seal is positioned radially between the piston rod and a first end of the damper tube. A cap is positioned over the first end of the damper tube and includes a side wall positioned in contact with and extending annularly about the first end of the damper tube. An end wall extends radially inwardly from the side wall. A collector radially outwardly extends from the side wall. The cap includes a vent. The side wall includes an end face at an opposite end of the cap as the end wall. The collector is positioned axially between the vent and the end face of the side wall. The collector includes surfaces on which oil passing by the piston rod seal will accumulate.

Abstract: A method of manufacturing a shock absorber includes inserting a floating piston into a tube, disposing oil into the tube, and inserting a piston-rod assembly into the tube. The piston-rod assembly has a piston coupled to a rod. The method includes inserting a rod guide assembly into the tube. The rod guide assembly includes a sintered metal rod guide having a seat and a seal disposed in the seat. The rod extends through the seal. The method also includes deforming a wall of the tube into engagement with the sintered metal rod guide to provide a piston-cylinder assembly and inhibit axial movement of the rod guide assembly relative to the tube. The method further includes pressurizing the piston-cylinder assembly and forming a flange portion of the tube over an upper surface of the sintered metal rod guide.
