Abstract
A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.

A bumper cap for a damper, the damper including an outer tube, the outer tube having an end, and a rod extending through the end in the outer tube, the damper including a damping fluid that is movable within the damper in response to movement of the rod, the bumper cap comprising:
- a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube and the base having a through hole in the base, the through hole configured to have the rod pass therethrough,
- the base having at least one fluid passage extending away from the through hole;
- the side wall having at least one fluid reservoir located in the side wall and in fluid communication with the fluid passage, the at least one fluid reservoir being radially between the inner surface and the outer surface of the side wall.
A damper comprising:
- an outer tube having an end;
- the outer tube having a rod, the rod extending through the end in the outer tube,
- the damper including a damper fluid, the damper fluid movable within the damper in response to movement of the rod;
- a cup shaped bumper cap configured to fit over the end of the outer tube, the bumper cap having a through hole, the rod passaging through the through hole,
