Embodiment Construction

[0040] figure 1A longitudinal section through a (not shown) valve control rod is shown schematically through a cylindrical spigot 1 comprising a first end wall 2 and a second end wall 4 delimited by an outer wall 6 . In addition, the bolt 1 also includes a blind hole 8 extending from the first end wall 2 to the opposite second end wall 4 , thereby forming a hollow inner space 10 of the bolt 1 . Here, the opening 12 of the blind hole is formed on the first end wall 2 and the bottom 14 of the blind hole is formed on the second end wall 4 . In order to fill the plug 1 with a fluid, in particular lubricating oil, the opening 12 of the blind hole comprises a closure member 16 such as a plastic plug. Furthermore, a fixing member 18 is provided for fixing the closure member 16 into the opening 12 of the blind hole. In general, it is also possible to close the opening 12 of the blind hole using other closure members, for example spherical members which can be secured in a tight fit....

Abstract

A cylindrical pin of a valve control lever has an outer side wall, a first end wall and a second end wall and includes a blind bore that extends from a blind bore opening in the first end wall to an inner surface of the second end wall, the inner surface forming a blind bore base, the blind bore base including at least one through opening.

Description

technical field [0001] The invention relates to a cylindrical spigot of a valve control lever, in particular in the form of a rocker arm or rocker, a method of manufacturing said cylindrical spigot, and a coating system. Background technique [0002] The cams of the camshaft are used for valve control in internal combustion engines. In an internal combustion engine, a valve control rod such as a rocker or rocker arm is used to transmit the motion of the cam to the valve. Generally speaking, the valve control rod includes a base body rotatably supported about an axis and includes a receptacle connected to the camshaft connection member, the receptacle being rotatably attached to the valve control rod via a peg. [0003] Said pins are usually arranged cylindrically and comprise a lubricant distribution device in order to make it possible to achieve lubrication between said pins and the camshaft connecting member and / or the valve control rods. For this purpose, the spigot ma...
