用于燃料高压泵的推杆组件及燃料高压泵
Abstract:
本发明涉及一种用于燃料高压泵的推杆组件，它使一个泵元件的可往复运动的泵活塞（1）支撑在一个驱动轴（3）的凸轮（2）上，该推杆组件包括一个具有凹槽（5）的支撑件（4），在该凹槽中可转动地支承一个滚子（6）。根据本发明，为了使滚子（6）保持在支撑件（4）的凹槽（5）中，还设有一个保持件（7），该保持件与支撑件（4）形状锁合地连接，其中该形状锁合防止保持件（7）相对泵活塞（1）的纵轴线（A）转动。
Abstract(English):

The invention relates to a plunger assembly for a high-pressure fuel pump for supporting a reciprocating pump piston (1) of a pump element on a cam (2) of a drive shaft (3), comprising a supporting element (4) with a recess (5), in which a running roller (6) is mounted rotatably. According to the invention, it is provided that, furthermore, a holding element (7) is provided for holding the running roller (6) in the recess (5) of the supporting element (4), which holding element (7) is connected to the supporting element (4) in a positively locking manner, wherein the positively locking connection brings about an anti-rotation safeguard of the holding element (7) with respect to a longitudinal axis (A) of the pump piston (1).
