Specific embodiment
Describe the ejection assemblies 1 of first preferred embodiment of the invention in detail below in reference to Fig. 1 to 8.
As visible from Fig. 1 and 2, ejection assemblies 1 include injector 2 and fuel bowl 3.Here, fuel bowl 3 is used for
Conveying and storage fuel, the fuel will be sprayed by injector 2.Fuel bowl is arranged in spray on the through-flow direction of injector
Before emitter.
Clamping lock attachment structure 4 is set between injector 2 and fuel bowl 3 and fixed structure 5 is reversed.
Here, clamping lock attachment structure 4 ensure that a fuel bowl 3 is axially fixed on injector 2.Axial direction is in accompanying drawing
In represented with axis X-X and define the axial direction of injector 2.
Clamping lock attachment structure 4 includes the first and second clamping lock hooks 40,41 and the first and second clamping lock notches 42,43.Such as
Especially from Fig. 2 and 3 it is visible as, the first clamping lock hook 40 is arranged in the first clamping lock notch 42, and the cloth of the second clamping lock hook 41
Put on the second clamping lock notch 43.
Reversing fixed structure 5 prevents rotating against between fuel bowl 3 and injector 2.Reversing fixed structure 5 includes stretching
Go out portion 50, the first contact surface 51 and the second contact surface 52 are constructed on the extension.Additionally, reversing fixed structure 5 also includes the
Three contact surfaces 53 and the 4th contact surface 54.
Additionally, the first protuberance 55 and the second protuberance 56 are arranged on fuel bowl 3.
In the assembled state, as especially as seen from Figure 4, the first contact surface 51 of extension 50 abuts in
On 3rd contact surface 53 of one protuberance 55, also, the second contact surface 54 of extension 50 abuts in the of the second protuberance 56
On four contact surfaces 54.
Therefore, by the contact surface 51,53 and 52,54 in contacting with each other, the torsion in two circumferential directions is realized
Turn fixed structure.
Fig. 5 to 8 shows in detail fuel bowl 3.Two clamping lock hooks 40,41 are reciprocally arranged in fuel bowl with 180 °
On.
First protuberance 55 and the second protuberance 56 stagger 90 ° of ground relative to clamping lock hook 40,41 on the periphery of fuel bowl 3
Arrangement.Here, the 3rd contact surface 53 and the 4th contact surface 54 are parallel to each other.
Extension 50 is thus, it is possible to be coupled in the intermediate space between the first protuberance 55 and the second protuberance 56.
As especially as can be seen from Fig. 4, here, compared with the first attachment structure 4 (length L2), reversing fixed structure
5 arrange on the axial direction X-X of injector 2 closer to the ground of free end 30 of (length L1) fuel bowl 3.Therefore, combustion
Material cup 3 is placed to when on injector 2, is by reversing the four of fixed structure by reversing fixed structure 5, more speaking by the book
Contact surface realizes guiding function.And then the clamping lock of clamping lock attachment structure 4 is just made, its mode is clamping lock hook 40,41 is coupled to
One and second in clamping lock notch 42,43.
As visible especially from Fig. 1 and 2, here, the first and second clamping lock notches 42,43 and extension 50 are arranged
On common component, it is used for the connector injection encapsulated portion 6 that the electric contact of injector 2 is connected.Here, connector injection encapsulated portion
6 in circumferential direction completely bag hold injector 2.Therefore, the part of the part and clamping lock attachment structure of reversing fixed structure can
It is set to the part in die cast component, i.e. connector injection encapsulated portion 6, and therefore, it is possible to manufacture cost-effectively and simply.
By between clamping lock attachment structure 4 and torsion fixed structure 5, separation of the invention, it is furthermore possible in handle
Fuel bowl 3 is assembled to the guiding function (length L1 ＜ length L2) for ensuring to reverse fixed structure 5 when on injector 2.
It is assemblied in without error on fuel bowl 3 invention thus achieves injector, wherein, it is not necessary to additional orientation
Component is such.Clamp connection or such also without metal.Additionally, in injector 2 and fuel bowl 3
Between, the such configuration of attachment structure of the invention：The component that need not be added, such as metal clip or such.
First and second clamping lock hooks 40,41 and the first and second protuberances 55,56 are integrally provided with fuel bowl 3 again,
Preferably it is similarly arranged to die cast component.Also therefore, it is possible to cost-effectively providing clamping lock attachment structure 4 and reversing fixed structure
5。
The present invention especially with compact internal combustion engine, the compact internal combustion engine for dilly typically without (fuel injection) rail
It is used in combination, the dilly is, for example, two-wheel car, tricycle or carriage or such.In this ejection assemblies
In, it is necessary to simple and reliable assembling is ensured, because the assembling is often for example likely to by low water in maintenance and repairing
Flat labour implements.Here, wrong assembling can not produced between fuel bowl and injector.In addition ensure that, spray
Device 2 is always assemblied on correct position, typically without undesirable torsion in circumferential direction, the undesirable distortional energy
Enough cause the wrong injection form (Spritzbild) of injector.
