Abstract
A moldable metering pin for an energy absorber unit includes an integral base having a plurality of openings. The base is press-fitted in an outer cylinder of the unit. The openings in the base prevent the formation of air pockets between the base and an end cap of the outer cylinder. During impact, fluid in a rear chamber passes to the end cap, thereby reducing fluid forces on the base of the metering pin.
