摘要:
The invention relates to a tappet (1) for a high-pressure fuel pump or for a valve drive of an internal combustion engine, comprising a housing (2) which has a cam run-on surface (4) on the drive side (3) thereof, wherein an output side (5) of the housing (2) rests on a lower face (6) of a bridge piece (8) that projects through an inner shell (7) of the housing (2), wherein an anti-turn lug (11) protrudes from the outer shell (10) of the housing (2) and is arranged in a window (9) in the latter, wherein said lug is substantially present as an upright body similar to a semi-cylinder in the region thereof protruding from the housing (2), and the outer surface (15) of said lug, in cross section, results in an ogival curve made up of two or more circular arcs (16).
摘要(中):
本发明涉及一种用于高压燃料泵或用于内燃机的阀驱动的挺杆(1),其包括壳体(2),壳体(2)在驱动侧(3)上具有凸轮延伸表面(4) ),其中所述壳体(2)的输出侧(5)搁置在通过所述壳体(2)的内壳(7)突出的桥接件(8)的下表面(6)上,其中, 所述凸耳(11)从所述壳体(2)的外壳(10)突出并且布置在所述壳体(2)的窗口(9)中,其中所述凸耳基本上呈现为类似于半圆柱体 其从壳体(2)突出的区域和所述凸耳的外表面(15)的横截面形成由两个或多个圆弧(16)组成的奇异曲线。
