ABSTRACT:
Bleed orifices are formed in the lower end of the rod guide of a double acting hydraulic strut or shock unit. The bleed orifices are of sufficient size and number that when a rod guide designed for a larger bore unit is assembled in a unit with a smaller bore cylinder tube, a large fluid leak path is produced between the cylinder tube and the reservoir tube. This leak greatly reduces rebound damping force that the unit normally produces. When checked for damping performance before final shipment of the unit, the low damping force is readily detected and the unit is rejected for repair.
