尤其是用于内燃机燃料喷射装置的高压泵
摘要：
本发明涉及一种尤其是用于内燃机燃料喷射装置的高压泵，具有一驱动轴(12)，该驱动轴具有至少一个凸轮(16)或偏心轮，具有至少一个泵元件(18)，所述泵元件具有一泵活塞(20)，该泵活塞被所述驱动轴(12)的凸轮(16)或偏心轮驱动进行行程运动。在该泵活塞(20)与所述驱动轴(12)的凸轮(16)或偏心轮之间设置有一支撑元件(44)和一在该支撑元件中可旋转地支承的、在凸轮(16)或偏心轮上滚动的滚子(46)。在所述滚子(46)的旋转轴线(47)的方向上在该滚子旁边设置有一用于该滚子(46)的支撑装置(60)。滚子(46)和/或该支撑装置(60)至少在该滚子(46)与该支撑装置(60)之间的接触区域中具有一个具有高磨损强度的表面。
摘要（英）：

The high pressure pump comprises a drive shaft (12) with at least one cam (16) or eccentric and at least one pump element (18) with a pump piston (20), driven in the reciprocating direction by the cam (16) or eccentric on the driveshaft (12) in a reciprocating motion. A support element (44) is arranged between the pump piston (20) and the cam (16) or eccentric on the driveshaft (12) and also a roller (46) running on the cam (16) or eccentric is mounted to rotate therein. A support (60) for the roller (46) in the direction of rotation is arranged adjacent to the same in the direction of the rotational axis (47) of the roller (46). The roller (46) and/or the support (60) comprises a surface with high wear resistance at least in the contact region between the roller (46) and the support (60).
