Abstract
The utility model provides a fuel oil return hose assembly. The fuel oil return hose assembly comprises a rubber tube, a first nylon tube, a second nylon tube, a third nylon tube and a fourth nylon tube, wherein the rubber tube is communicated with the first nylon tube and the second nylon tube through a three-way union, the second nylon tube is communicated with the third nylon tube and the fourth nylon tube through a three-way union, the rubber tube is used for being connected with an oil return tube of a fuel injector, and the first nylon tube, the third nylon tube and the fourth nylon tube are used for being connected with an oil pump, a fuel rail and an oil tank respectively. The fuel oil return hose assembly has the advantages of being simple in structure and flexible in arrangement.
Description
Technical field
The utility model relates to engine art, is specifically related to the return flow oil hose assembly of motor.
Background technique
Diesel engine fuel oil return line is the important spare part of motor, is component important in engine fuel system.Along with the increasingly stringent of domestic and international Abgasgesetz, diesel engine has gradually adopted electric-controlled co-rail system to replace original mechanical oil supply system, and variation has also occurred in corresponding return flow oil pipeline design.
What existing diesel engine product intermediate fuel oil return tube major part adopted is rubber material or tube material, and two ends are fixed on oily rail and oil pump with clip; This kind of scheme dismounting relatively bothers, and remove clip and just can unload bottom hose, and the immovable point that flexible pipe needs is relatively many, and another middle if any steel pipe connection, component seem too much.
Model utility content
The purpose of this utility model is to provide a kind of return flow oil hose assembly of simple in structure, flexible arrangement.
For achieving the above object, the utility model provides following technological scheme:
A hose assembly, comprising: rubber pipe; First to fourth nylon tube; Described rubber pipe is communicated with the first and second nylon tubes by three-way union, described the second nylon tube is communicated with the third and fourth nylon tube by three-way union again, described rubber pipe is used for connecting oil sprayer return tube, and described the first nylon tube, the 3rd nylon tube and the 4th nylon tube are respectively used to be connected oil pump, oily rail and fuel tank.
Preferably, described the first nylon tube, the 3rd nylon tube and the 4th nylon tube are equipped with quick-acting joint.
The beneficial effects of the utility model are:
The whole pipelines of the utility model have adopted hose construction, without steel pipe, have reduced component, and the difference of the parts that will connect for pipeline adopts respectively rubber pipe or nylon tube, facilitate line arrangement.
Further, quick-acting joint facilitates pipeline dismounting.
Accompanying drawing explanation
Next in connection with accompanying drawing, specific embodiment of the utility model is described in further detail, wherein:
Fig. 1 is the mechanism map of embodiment's of the present utility model return flow oil hose assembly;
Fig. 2 and Fig. 3 show respectively two three-way unions in Fig. 1.
Description of symbols in upper figure: rubber pipe 1, the first nylon tube 2, the second nylon tube 3, the 3rd nylon tube 4, the 4th nylon tube 5, three-way union 6, three-way union 7, quick-acting joint 8, quick-acting joint 9, quick-acting joint 10.
Embodiment
In conjunction with Fig. 1 to Fig. 3.Return flow oil hose assembly comprises: rubber pipe 1, first to fourth nylon tube 2,3,4,5.Rubber pipe 1, for connecting oil sprayer return tube (not shown), because arrangement space is narrow and small and bending variation place is many, therefore adopts quality of rubber materials, and because this joint does not need frequent dismounting, so adopt clip.The first nylon tube 2, the 3rd nylon tube 4 are respectively used to be connected oil pump, oily rail and fuel tank (not shown) with the 4th nylon tube 5, and these three nylon tubes preferably arrange quick-acting joint 8,9,10, are convenient to dismounting.Rubber pipe 1 is communicated with the first and second nylon tubes 2,3 by three-way union 6, and the second nylon tube 3 is communicated with the third and fourth nylon tube 4,5 by three-way union 7 again, thereby realizes the connection of return flow oil oil circuit.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and be only subject to the restriction of claim, those of ordinary skills can carry out equivalence to it at an easy rate and replace or modification, but do not leave essence design of the present utility model and scope.
Claims (2)
