Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model oil return pipe component embodiment one.
Embodiment
Fig. 1 is the structural representation of the utility model oil return pipe component embodiment one.As shown in Figure 1, the oil return pipe component that the present embodiment provides specifically can be arranged between oil sprayer and fuel tank, concrete, the oil return pipe component that the present embodiment provides can comprise: the pipe joint 101 connected successively, body 102, interconnecting part 103 and return opening 104;
Wherein, described interconnecting part 103 comprises fixed plate 1031, first opening and the second opening; Described first opening is connected with described body 102, and described second opening is connected with described return opening 104, and described return opening 104 is connected with described fuel tank; Described fixed plate 1031 covers for described interconnecting part 103 is fixed on engine cylinder.
It should be noted that, in the present embodiment, pipe joint 101 can be connected with oil return of oil injector mouth, from oil return of oil injector mouth flow out oil return through pipe joint 101, body 102, interconnecting part 103 and return opening 104, finally flow back to fuel tank.
Concrete, with use in prior art the scheme of seal ring and binder connecting tube joint 101 and body 102 unlike, the oil return pipe component of the present embodiment utilizes Pneumatic pressure by pipe joint 101 together with body 102 assembly and connection, pipe joint 101 does not need filled media and binder with the joint of body 102, after using Pneumatic pressure pipe joint 101 and body 102 to be linked together, can ensure that body 102 is greater than 140N with the pull-out force of pipe joint 101, thus ensure that pipe joint 101 can not exist less relative displacement because the vibration frequency of high pressure oil pump and oil sprayer is different between body 102, in addition, body 102 can adopt has anti-aging, high temperature resistant, resistance to high and cold, vibration resistance and the macromolecular material oil-resistant pipe of leakage proof, solves the problems such as return tube leakage of oil, aging, spalling, makes motor safety and reliability.
Further, fixed plate 1031 is fixed on engine cylinder by least one bolt 1032 and covers, and as shown in Figure 1, in the present embodiment, by two bolts 1032, fixed plate 1031 is fixed on engine cylinder and covers; The present embodiment does not limit this.
It should be noted that, the quantity of pipe joint 101 specifically can be determined according to the quantity of cylinder, and such as, motor has four cylinders, then arrange four pipe joints 101.The present embodiment does not limit this.
In a kind of feasible mode of execution, described interconnecting part 103 can also comprise the 3rd opening; Described 3rd opening can be connected with high pressure oil pump return line 105.Concrete, interconnecting part 103 can be three-way valve, then, after the 3rd opening of this three-way valve is connected with high pressure oil pump return line 105, from the oil return of high pressure oil pump outflow through high pressure oil pump return line 105, three-way valve and return opening 104, finally flow back to fuel tank; Thus high pressure oil pump return line 105 can be reduced.
In another feasible mode of execution, in order to control the pressure difference in return tube body, control system return pressure and system oil return flow, the return pressure of oil sprayer is made to meet code requirement, ensure the accuracy of fuel injection quantity and prevent oil return from flowing backwards, as shown in Figure 1, the oil return pipe component that the present embodiment provides can also comprise the one-way valve 106 be arranged between described body 102 and described first opening, thus avoid oil return to flow backwards, effective control system return pressure and system oil return flow.
The oil return pipe component that the present embodiment provides, is arranged between oil sprayer and fuel tank, by arranging the pipe joint, body, interconnecting part and the return opening that connect successively; Wherein, described interconnecting part comprises fixed plate, the first opening and the second opening; Described first opening is connected with described body, and described second opening is connected with described return opening, and described return opening is connected with described fuel tank; Described fixed plate is used for that described interconnecting part is fixed on engine cylinder and covers.Wherein, cover because described oil return pipe component is fixed on described engine cylinder by described fixed plate, described oil return pipe component is relative with the position of motor fixing, return tube can be made to vibrate with motor, avoid the fault producing fracture leakage of oil at engine operation process middle tube body due to vibration, improve motor reliability of operation and Security.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
