Pump element for high-pressure fuel pump in fuel injection system, has force transmission element that rests against face surface of plunger body or supporting element in which recess is formed within diameter of body or supporting element

摘要

The element has a plunger component (2) comprising a plunger body (3) rotatably mounted on a roller (4) for supporting a pump piston (1) at a cam of a drive shaft of a high-pressure fuel pump. A force transmission element (8) is arranged between the pump piston and the plunger body or a supporting element in the plunger body for a rotatable storage of the roller. The force transmission element rests against a face surface of the plunger body or the supporting element in which a recess (10) is formed within diameter of the plunger body or the supporting element.
