Accordingly, there exist the not valve rocker with disadvantages mentioned above.Briefly, the subregion " shifting " in spherical crown portion is to adjacent
Side wall in.Therefore, in cross-section, there is no the material with the danger for forming crackle, protuberance etc. and double thickening portion.From now
Starting, the bar with relatively small quality be configured in ball crown areas be it is long and narrow, and can be without with around
In the case of the danger of member impacts well (in the way of quality controlled or controlled amounts) construction minification internal combustion
In the cylinder head of machine.Additionally, the valve rocker is highlightedly suitable as propelling cam valve device
(Schiebenockenventiltrieb) cam pack in.Up to now the support component for using is necessarily in its top region
Reduce in domain.
Especially consider the sheet material of steel or aluminum as the valve rocker for the manufacture of preferred bending ram of thin-walled.If necessary,
It is also contemplated for other lightweight materials, also fiber or the enhanced lightweight material of granule.As an alternative, bar being capable of molding ground
(urformtechnisch) or by cutting make.
With protection domain relatively, the construction unit being made up of valve rocker and support component is optionally also by holding
Fixture connects on one end, or by the component that only valve rocker with holding fixture is constituted.
Especially, (but being for example used not only for fuel penetrating) should use in valve device or pump drive assembly
Valve rocker (also has rocking bar) as an alternative.However, for example also valve rocker can be applied to compressor or other medium is defeated
In sending device.
An especially preferred composition scheme of the invention, the longitudinal portion between the other end and cam working face
Duan Zhong, side wall are associated with crossbeam.Therefore, it is clear that：Valve rocker substantially has inverted U-shaped profile, and its crossbeam court
To corresponding cam or eccentric.
In addition propose：Observe on the longitudinal direction towards an end, valve rocker has company at cam working face rear
The midfeather of the side wall of the valve rocker is connect, crossbeam flatly extends to the other end as far as possible from the downside of the midfeather
Portion, the crossbeam have the spherical crown portion that here shapes.Therefore, finally, in this region, U shape profile is overturned.
According to another design, valve rocker is without side wall an end.The measure is used to simplify manufacture, and
And save weight and material.As an alternative, side wall or part thereof region can also start from an end.
According to another dependent claims, side wall starts from an end and at least extends to midfeather without swell straight.Cause
This, makes in terms of simplifying design and saving structure space and further contributing.In addition propose：Valve rocker is complete along its longitudinal direction
It is complete straight to constitute without swell, or at least up to its cam working face in or (hold from one at its cam working face rear
Portion rise observation) a section or the longitudinal section only in cam contact surface be raised slightly.
Another dependent claims are related to the simple scheme of the form of expression of material recess in the sidewall.Accordingly, for example
Recess should be produced by suppressing, this can be carried out before side wall is erected on slab.If necessary, it is also possible to carry out impact extrusion
Or cutting.As an alternative, recess can be used as window presence so that the completely no material of corresponding side of sidewall portion section.
In order to realize fastening feasibility of the holding fixture an end, crossbeam should be provided with two marginal area
Breach or like configurations so that the material tongue-like part in central authorities is remained with crossbeam.
