Abstract
The invention relates to a resilient sleeve, especially for injection valves on Otto engines, which is suitable for compensating manufacturing and adjustment tolerances effectively and reliably. This takes place through rolling out processes on two diametrically opposite caps (14) in a first direction and through the displacement of diametrically opposite, arched elastic elements (15) in a second direction at right angles to the first.
Description
Technical field
The present invention relates to a kind of resilient sleeve, especially for the resilient sleeve of the injection valve of Otto engine.
Background technique
Injection valve is fixed on the cylinder head by pallet or locking nut usually.Its shortcoming is, almost always generates the impacting force of uneven distribution.Its result produces sealing problem.In above-mentioned prior art, inevitably and inevitably temperature variation and the uneven temperature distribution that occurs causes very big problem.
If on manufacturing process, occur stopping, with respect to the error of rating value, then also produce corresponding problem quite at large.Its consequence is identical with described in the preceding paragraph almost.
Summary of the invention
Task of the present invention is to provide a kind of available sleeve as intermediary element, can produce by temperature variation, uneven temperature distribution and manufacturing tolerances with a spot of cost compensation with this sleeve, with respect to the error of rating value given in advance.
The technical solution of above-mentioned task is a kind of resilient sleeve that is used for the injection valve of Otto engine, wherein, this resilient sleeve has one and radially has two windows on the relative position at circumference that is closed to 90 ° of subtended angles on the planimetric map and in a upper area two, these two windows arched part closure of elastically deformable, described arched part constitutes the top of supporting point.
A kind of such sleeve that is designed to spring element can produce the tension force of high qualification on the one hand, can compensate again on the other hand between two supporting surfaces of sleeve form error and with respect to the error of rating value, do not damage function in addition.
Further because above-mentioned sleeve is made one that the medial axis become flexible structure and can prolong the x axle and y axle offset angle deviation and transverse force, so the cooperation that has guaranteed reliably, sealed.
Description of drawings
Below, illustrate the present invention with reference to accompanying drawing.Accompanying drawing is depicted as:
Fig. 1 is the side view according to resilient sleeve of the present invention along the I-I among Fig. 2, and this resilient sleeve is round basically, along about 270 ° circumferential extension,
Fig. 2 is the plan view of such sleeve,
Fig. 3 is the side view along the resilient sleeve of the III-III among Fig. 2,
Fig. 4 is the unfolded drawing of such resilient sleeve.
Embodiment
Resilient sleeve 10 supporting surfaces 11 that in one plane stretch by it, be positioned at right hand edge in Fig. 1 shown in Fig. 1 are provided with in one plane.If this sleeve is the injection valve that is applicable to Otto engine, then sleeve 10 is arranged in the corresponding columniform hole of cylinder head by its flat supporting surface.The other end that is illustrated in the left side among Fig. 1 12 of resilient sleeve 10 is bearing on second plane, and one so-called " track " (fuel rail) can be represented having in this plane on the Otto engine of fuel injection apparatus.
As can be seen from Figure 2, the periphery of resilient sleeve 10 advantageously stretches along about 270 ° angle of circumference.Therefore surplus next about 90 ° circumference subtended angle.On the one hand, this subtended angle can make sleeve along the circumferential direction have higher flexibility.Under corresponding situation of exerting all one's strength, the diameter of sleeve can enlarge in certain scope, perhaps also can dwindle.On the other hand, this subtended angle fuel pipe joint and electrical connector that can be used in injection valve can enter from the side.
As can be seen from Figure 3, be positioned at the upper area of sleeve as the part of an arch of the top boundary of window 13.The part of these arch structure is bearing on above-mentioned " track " of motor with its top 14.
Resilient sleeve 10 has two windows 13 on relative position radially, these two upper parts that window 13 has the closure of arch.
When the angular deviation of supporting surface appears in the x direction, when error angle β promptly occurring, by on land portions on the arch, promptly the scrolling realization on top 14 compensates automatically.When angular deviation α occurring on the y axis, the skew of the spring by two arch varying strengths of 15 equally also can realize automatic compensation.
Such resilient sleeve 10 can be with the simplest method by suitable flat bar manufacturing.During manufacturing, the blank of sleeve at first has shape shown in Figure 4.By known production stage, be processed into above-mentioned sleeve 10 by flat blank, this sleeve has the basic circular circumference that is.
After BENDING PROCESS, resilient sleeve further stretches along an about angle of circumference of 270 ° as described above.
The manufacturing of sleeve 10 only needs a spot of processing charges, and has replaced a large amount of present required parts.Therefore, particularly in modernized pipelining, embodied very big superiority.
The arch 15 that is positioned on the y axis has the characteristic of spring.Therefore, shown in Fig. 1 was concise and to the point, a slight deformation arch 15 or another arch 15 of error angle a by sleeve 10 that roughly is positioned on the y axis compensated.The softness of arch 15 and consequent spring action can be affected by the second less arch 15a.
When the error angle β of Fig. 3 shown in concise and to the point occurring, the face on the top 14 there of being bearing in can push up at this and roll on 14 and therefore along the x direction error angle β is compensated.
At last, the effective diameter of sleeve 10 also can be revised by resiliently deformable.Realize dwindling of effective diameter by elastic compression to sleeve wall.When corresponding power alleviated, diameter enlarged once more.
The flat blank of the sleeve shown in Fig. 4 can be made with flat bar in one procedure in enormous quantities.
Can compare with the performance of the huge cross-pin type joint of cost with the overall performance of the sleeve 10 of low cost manufacturing.
