The fuel oil return structure for air volume of prior art is larger, take up room larger, and body weight is large, need to be fixed by bolts in suction tude, and oil sprayer return tube 60, common rail return tube 80 and oil pump return tube 40 are longer simultaneously, and holistic cost is higher.
Model utility content
The utility model is in order to overcome defect in above-mentioned prior art, by the return flow oil device with cavate body, adopt self-supporting mode to fix, in the volume that reduces return flow oil device, shorten the length of oil sprayer return tube, common rail return tube and oil pump return tube.
For realizing above-mentioned model utility object, the utility model provides a kind of return flow oil device, comprising: body, and it is compartment shape; Oil pump back leakage connection, it is taken over and to be fixedly installed on body by oil pump oil return, and oil pump oil return takes over and be provided with union nut, and oil pump back leakage connection is removably fixedly connected with oil pump return tube; And return flow oil joint, common rail pipe back leakage connection and oil sprayer back leakage connection, its one end is removably fixedly connected with oil sprayer return tube with fuel oil return pipe, common rail return tube respectively, and the other end is all fixedly connected with body.
The body of cavate has reduced the volume of return flow oil device greatly, has reduced and has taken up room, and has greatly shortened oil sprayer return tube, the length of rail return tube altogether simultaneously, has saved oil pump return tube, has reduced cost.
In technique scheme, body is the sphere-like that scabbles up and down, rectangular-shaped or cube-shaped.。
In technique scheme, one or more in return flow oil joint, common rail pipe back leakage connection and oil sprayer back leakage connection are lining.Bush type pipe connects the difficulty that has reduced pipeline connection, is convenient to maintenance.
In technique scheme, oil pump back leakage connection is cutting ferrule.
In technique scheme, oil pump oil return is taken over as hard metal pipe.Lightweight due to cavate body, so the oil pump oil return of hard metal tubulose takes over and can make return flow oil device self-supporting on oil pump, saved installation process.
In technique scheme, oil pump oil return is taken over as steel pipe.Steel pipe is conventional metal tube, the cost of material that can save return flow oil device.
