High pressure injection pump, has housing in which pump pistons are provided, where pistons abut against pressure surface, pressure plate arranged in bucket tappet, and pistons self adjustably supported at pressure plate

摘要

The pump has a housing in which radially aligned three pump pistons (2) are provided. The pump pistons abut against a pressure surface via a tappet rod. A spring cup is fastened to the pump pistons, where the tappet rod comprises a slidingly guided hollow shaft sleeve and a pressure plate (6). The pressure plate is arranged within a bucket tappet (9) and the pump pistons are self adjustably supported at the pressure plate.
