Description
Technical field
The present invention relates to a kind of automobile fuel pump parts, especially a kind of electric fuel pump assembly.
Background technique
Electric fuel punp is mainly the fuel oil that certain pressure is provided for automobile fuel injection system, and at present, electric fuel pump assembly is of a great variety both at home and abroad.Comprise oil-storing barrel, fuel pump, flowline, oil returning tube, flange.Oil-storing barrel is placed in fuel tank, and flange is arranged on the lid of fuel tank button.Existing oil-storing barrel is sealing bucket, and oil-feed is by one-way valve and the oil-feed of umbrella valve of oil-storing barrel bottom, and can not well guarantee has fuel oil, the suction phenomenon may cause automobilism time always in end bucket.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of simple in structure, oil-feed is effective, suction phenomenon while avoiding automobilism, the electric fuel pump assembly of oil-storing barrel is flowed out in oil return rapidly while avoiding recirculating oil quantity larger.
Technological scheme of the present invention is as follows: a kind of electric fuel pump assembly, it is characterized in that: the oil-storing barrel (1) that comprises upper end open, electric fuel punp (2), flowline (3), flange (4), oil returning tube (5), pressure regulator valve (6), injecting valve (7), unidirectional oiling valve (8), overhead gage (9), (10) and lower pedal (11) are highly managed in oil return, described electric fuel punp (2) is arranged on the right part in oil-storing barrel (1), the bottom of described oil-storing barrel (1) is provided with unidirectional oiling valve (8), described flowline (3) is connected with the oil outlet of electric fuel punp (2), on described oil returning tube (5), be connected with pressure regulator valve (6) and injecting valve (7) in turn, wherein said injecting valve (7) is positioned at the outer lower left quarter of oil-storing barrel (1), the left part of described oil-storing barrel (1) inner bottom plate is provided with vertical oil return and highly manages (10), the oil outlet of described injecting valve (7) is connected with the import that (10) are highly managed in oil return, the bung that the oil-storing barrel (1) of (10) top is highly managed in described oil return is provided with the overhead gage (9) of avoiding oil return ejection, the free-ended lower end of described overhead gage (9) is provided with lower pedal (11), described flange plate (4) is positioned at the top of oil-storing barrel (1), the oil outlet of the filler opening of described oil returning tube (5) and flowline (3) is all arranged on flange (4).
Adopt technique scheme, we are designed to oil-storing barrel open, and fuel oil, except entering from one-way valve, can also enter from the upper end of oil-storing barrel.Unnecessary fuel oil arrives injecting valve after pressure regulator valve again in addition, and after injecting valve, fuel flow rate is larger, then by oil return height pipe inspection out, returns oil-storing barrel, and guarantee has fuel oil in oil-storing barrel always, avoids suction.The oil return of ejecting in addition forms negative pressure, the fuel oil being conducive in fuel tank enters in fuel reserve tank by one-way valve, meanwhile, the fuel oil of ejection, under the effect of overhead gage, can avoid oil return directly to spray outside oil-storing barrel, under the effect of lower pedal, the fuel oil bottom horizontal flow sheet of avoiding ejection in the time that oil return is larger, outside inhomogeneous outflow oil-storing barrel, causes larger flowing water sound rapidly, fuel oil is only overflowed from the periphery of fuel reserve tank, reduce noise.
In technique scheme: in order to facilitate the installation of injecting valve, the lower left quarter of described oil-storing barrel (1) is provided with the breach for placing injecting valve (7), and described injecting valve (7) is arranged in this breach.
As preferably: the width of described overhead gage (9) is that the bung width of oil-storing barrel (1) is 1/5th to 1/4th.
Beneficial effect: the present invention is reasonable in design, simple in structure, easily implements, and oil-feed is effective, suction phenomenon while avoiding automobilism, avoids oil return to flow out rapidly oil-storing barrel, causes larger noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
