Description
Technical field
The utility model relates to a kind of frock, and the common-rail injector entering interior oil return type in specific design is a kind of passes in and out oily frock.
Background technology
Return frock in entering in traditional and common are 2 types: one is socket type, and one is anchor ear type.
There is some shortcoming following in socket type frock:
1, due to inner in frock at oil-in, whether there is leakage so cannot observe, if a large amount of leakages cannot set up rail pressure or cause oil return numerical value to become large, but then cannot observe for tiny leaks, directly have influence on the maintenance precision of fuel injector, cause erroneous judgement; 2, poor universality, because fuel injector specification is many, appearance and size and angle are all different, so the fuel injector running into different size manufactures frock after needing to obtain physical dimension again, and can affect the maintenance process of vehicle; 3, install inconvenient, incorrectly cause leakage of oil owing to installing, need dismounting for several times normally to use.
There is some shortcoming following in anchor ear type frock:
1, poor universality, can not adapt to different fuel injector clampings.Be that oil-in angle is different mainly due to one, and the angle of thread on anchor ear is fixing, so must do the anchor ear of different angles; Two is oil return openings that anchor ear can block diverse location, and three is that oil-in is different apart from bed-plate dimension A, and anchor ear can be caused to embrace incessantly oil injector body.When 2, installing for the angled oil-in of band, anchor ear enclasping force is eccentric, and push rod top does not tightly produce leakage.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provide a kind of in enter interior oil return type common-rail injector pass in and out oily frock.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The common-rail injector entering interior oil return type in the utility model is a kind of passes in and out oily frock, comprises interior oil return frock and interior oil-feed frock, and described interior oil return frock is provided with oil return and twists joint soon, and described oil return is twisted joint soon and connected oil return anchor ear by oil return push rod; The middle part of the oil-feed anchor ear in described interior oil-feed frock is provided with circular hole, and described common-rail injector is vertically arranged on the circular hole of interior oil-feed frock, and described interior oil return frock is connected with common-rail injector by oil return anchor ear.
Further, angle-regulating block is provided with inside described oil-feed anchor ear, described angle-regulating block two ends are equipped with angle screwing screw, and oil-feed push rod runs through angle-regulating block and is arranged at angle-regulating block upper center by push rod swivel nut, in the middle part of described angle-regulating block lower end, be provided with angular adjustment screw.
Further, described oil-feed anchor ear is positioned at the reverse side of angle-regulating block and is provided with anchor ear screwing screw.
Further, described oil-feed anchor ear adopts spring flap-type mechanism.
The beneficial effect that the utility model reaches is: the common-rail injector entering interior oil return type in this kind passes in and out oily frock, versatility is wide, the installation of most of fuel injector on the market can be applicable to, reliability is high, oil-feed and oil return are separated completely, ensure that accuracy and the high accuracy of test, easy for installation, be easy to observe, angular adjustment is convenient.
