Background technology
Under the fuel injection system situation of motor vehicle, it can be envisaged that use fuel distributor pressing plate, the fuel distribution
Device pressing plate is made in steel or aluminum, it is adaptable to high-pressure applications.Thus, the compression strength of such as 20MPa (200bar) pressure is reached.So
And, the massive configuration of this track suitable for high-pressure applications is associated with manufacturing cost high.
Additionally, the fuel distributor pressing plate for being applied to 0.3MPa (3bar) to 0.5MPa (5bar) low-pressure applications can be additionally used in
Mentioned purposes.Herein, such as thin-wall steel tube can be used to manufacture the fuel distributor pressing plate.However, this be applied to
The range of application of the fuel distributor pressing plate of low-pressure applications is limited in mentioned low pressure range.
The content of the invention

The favourable of the fuel distributor that can obtain being given in preferred embodiment by the measure enumerated in alternative embodiment changes
Enter scheme.
In an advantageous manner, the matrix of the tubulose is designed as injection molding member, wherein, injection direction is parallel to the pipe
The longitudinal axis of the matrix of shape.By the arranged off-centre of the clear opening, stress level when bearing load is generally reduced.By institute
Injection direction is stated along the longitudinal axis, is observed on injection direction, a weld seam is formed after the open-work.It is described due to arranged off-centre
Weld seam is obliquely set.Due to therefore improving intensity, on desired allowable load, especially stress level, the tubulose
Matrix can be manufactured with the wall thickness that reduces by plastics.Thus, during the circulation of cool time when relying basically on injection moulding
Between reduce.
Advantageously, the edge of the open-work is constituted in the region of a weld seam towards the weld seam non-concave.Non-concave
Moulding includes the almost moulding of straight line and the moulding of convex herein.The non-concave at open-work edge is arranged in by the weld seam
Duan Shang, weld seam is present in the region of smaller mechanical stress.Specifically, the weld seam is herein away from the side of the open-work
The peak stress ground arrangement occurred in the recessed round region of edge.Because local material intensity reduces in welded seam area, but shadow simultaneously
Stress distribution in the matrix of the sound tubulose, so that the stress on the weld seam reduces, the intensity of the matrix of the tubulose is total
It is enhanced on body.
Herein additionally advantageously, the edge of the open-work has a straight section in welded seam area.Specifically, it is advantageous to
The open-work is designed as the open-work of long hole shape, and the open-work of the long hole shape takes on the circumferencial direction on the longitudinal axis
To.The long hole shape open-work can make weld seam be arranged in straight flange rim segment area relative to the circular through-hole with identical fluid cross-section
In domain, so that the weld seam is away from the peak stress in the fringe region of the elongated open-work.
But additionally advantageously, the edge of the open-work is convexly constituted in the region of the weld seam towards the weld seam.Cause
This, the stress occurred in the welded seam area equally reduces in the plastic.
Additionally advantageously, hole size of the open-work on the circumferencial direction on the longitudinal axis is more than the open-work along the longitudinal axis
Longitudinal direction on hole size.Especially, ellipse moulding is capable of achieving, wherein, in the most weak song of the oval open-work
In the region of rate, the weld seam is adjacent with the open-work.Thus, the mechanical stress of local reduction is similarly obtained in welded joints, from

Realize in thick portion.This is thus able to simply be realized in terms of ejection technique, wherein in injection moulding under situation, during the circulation
Between, especially cool time only mild prolonged.By a big surface, the stress even can equally reduce, and
It is laid in outside the weld seam, but the wall thickness substantially increases herein, and this has a negative impact to circulation time and thus carries
Manufacturing cost high.Thus it is further advantageous that the surface of the non-concave is in the longitudinal direction of the longitudinal axis along the elongated fuel chamber
Extension on direction at least unilaterally exists more than the size of the open-work, and the surface of the non-concave in a longitudinal direction
Extension on the circumferencial direction of the longitudinal axis on the elongated fuel chamber is located at described in a circumferential direction in both sides
The hole sized internal in hole.Thus, just the tubulose formed by plastics matrix the regional area of weakness because of weld seam
In can locally improve intensity.Additionally, by this measure, volume of the maximum stress and also where high stress in itself is subtracted
It is small.Therefore, the part density of load increases.
Particularly advantageously, the surface of non-concave is designed at least as the surface of near flat on inwall.By non-concave
The flat moulding on surface, is capable of achieving the strength of materials or wall thickness increases to a certain extent, but the increase is for the cooling not
Be it is important and thus the circulation time, especially cool time in injection moulding only somewhat extend.Therefore, in manufacture
Under conditions of cost is not improved, the part load capacity can be enhanced.This is especially in small flat surfaces less than open-work
It is such case during outlet.
