Description
Technical field
The present invention relates to a kind of component of automotive power transmission system, relate in particular to a kind of fuel pump of automotive power transmission system.
Background technique
The fuel pump device of automotive power transmission system all includes diapire, and diapire is arranged on the bottom of the fuel pump device of automotive power transmission system, for storing fuel oil, required in order to fuel pump body pump oil.But, the diapire of the fuel pump device of existing automotive power transmission system only plays merely the function that stores fuel oil, and fuel oil can produce in diapire bottom sludge in storing process owing to remaining static for a long time, those sludges can directly affect the quality of fuel oil, affect the pump oiliness energy of fuel oil pump assembly simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: a kind of fuel pump device that can avoid the automotive power transmission system that impurity is piled up, pump oil is effective is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of fuel pump device of automotive power transmission system, comprise bead, oil outlet tube, jet pipe, spout, fuel pump body, diapire and detection device, diapire is connected with detection device with bead respectively, fuel pump body is arranged on diapire inside, oil outlet tube one end is connected with bead, the other end is connected to fuel pump body, jet pipe one end is connected with bead, the other end extends to diapire bottom, spout is arranged on diapire bottom, be connected with jet pipe, and part is arranged on diapire inside, the fuel pump device of this kind of automotive power transmission system also comprises an empennage, this empennage is arranged in diapire and is connected with spout.
The arcuation sheet body structure that described empennage is formed in one.
Described empennage reduces from empennage starting point to end gradually apart from the distance of diapire inwall.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention sets up a lamellar body empennage that is certain radian in diapire filler opening one side, when fuel oil enters diapire with certain speed by spout, this empennage make fuel oil around diapire inwall to be rotated counterclockwise, diapire is washed away.And empennage reduces from empennage starting point to end gradually apart from the distance of diapire inwall, at empennage lamellar body end, fuel oil increases around the speed of diapire inwall rotation, has further strengthened the effect of washing away diapire.Therefore, the present invention can make the fuel oil that enters diapire in the mode of whirlpool, diapire be washed away, and has effectively avoided the sedimentary generation of fuel oil, makes diapire be difficult for accumulation sludge, keeps fuel oil Chang Xin, has strengthened the pump oiliness energy of fuel oil pump assembly.In addition, the diapire of the fuel pump device of a kind of automotive power transmission system of the present invention also adopts macrostructure pattern, can realize low oil level fuel feeding.
Accompanying drawing explanation

Fig. 2 is the diapire scheme of installation of the fuel pump device of a kind of automotive power transmission system of the present invention;
Fig. 3 is the diapire side view of the fuel pump device of a kind of automotive power transmission system of the present invention;
In figure, be labeled as: bead 11, oil outlet tube 12, jet pipe 13, spout 14, fuel pump body 15, diapire 16, detection device 17, empennage 18.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Refer to Fig. 1 to Fig. 3, a kind of fuel pump device of automotive power transmission system, comprise bead 11, oil outlet tube 12, jet pipe 13, spout 14, fuel pump body 15, diapire 16, detection device 17 and empennage 18, diapire 16 is connected with detection device 17 with bead 11 respectively, fuel pump body 15 is arranged on diapire 16 inside, oil outlet tube 12 one end are connected with bead 11, the other end is connected to fuel pump body 15, jet pipe 13 one end are connected with bead 11, the other end extends to diapire 16 bottoms, spout 14 is arranged on diapire 16 bottoms, be connected with jet pipe 13, and part is arranged on diapire 16 inside, empennage 18 is arranged in diapire 16 and is connected with spout 14.
In this example, empennage 18 is formed in one and is the sheet body structure of certain radian, and its distance apart from diapire 16 inwalls reduces gradually from starting point to end.When fuel oil enters diapire with certain speed by spout 14, empennage 18 make fuel oil around diapire 16 inwalls to be rotated counterclockwise, diapire is washed away.And at the lamellar body end of empennage 18, fuel oil increases around the speed of diapire 16 inwall rotations, has further strengthened the effect of washing away diapire 16.
The present invention can make the fuel oil that enters diapire in the mode of whirlpool, diapire be washed away, and has effectively avoided the sedimentary generation of fuel oil, makes diapire be difficult for accumulation sludge, keeps fuel oil Chang Xin, has strengthened the pump oiliness energy of fuel oil pump assembly.
In addition, the diapire of the fuel pump device of a kind of automotive power transmission system of the present invention also adopts macrostructure pattern, can realize low oil level fuel feeding.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the above embodiment's variation, modification, all will drop within the scope of claim of the present invention.
