Method of manufacturing piston bush with piston slide bore - involves bore for control sleeve and window section in wall of control sleeve bore

摘要

The control sleeve is formed in an intermediate section of the slide bore. The process starts with a blank with two-end section. One blank end is bored such that its dia. corresponds to the sleeve retainer at an intermediate section of the blank. Then a blank end section is drawn such that a part, in which the sleeve retainer is formed, remains. Then a second slide bore is formed in the blank such that it extends from one blank end section to the other one. Then the window section is formed in the wall of the sleeve retainer. USE/ADVANTAGE - For IC engine fuel injection pump, with rapid work rate.
