Description
Technical field
The utility model relates to a kind of vehicle fuel pump assembly more particularly to a kind of fuel oil pump assemblies with jet pump.
Background technique
Fuel oil pump assembly is the important composition component of automobile oil supply system, generally comprises assembly shell and fuel pump, assembly
Shell is also auxiliary fuel tank, and fuel pump is arranged in assembly shell, and oil liquid first enters in assembly shell from automotive oil tank, then by fuel oil
Pump is transported to automobile engine system.The oil liquid of the prior art is to flow in assembly shell by its own gravity from automotive oil tank
, when oil level is lower in automotive oil tank, the oil level in assembly shell is relatively low, it cannot be guaranteed that fuel oil pump assembly is normally and efficiently transported
Row.
Utility model content
The purpose of this utility model is exactly to overcome the deficiencies of the prior art and provide energy when a kind of automotive oil tank is in low oil level
The fuel oil pump assembly normally and efficiently run.
To achieve the goals above, the technical solution of the utility model is such that a kind of fuel oil with jet pump
Pump assembly, including assembly shell and fuel pump, fuel pump are arranged in assembly shell, and the bottom of the assembly shell is equipped with one
A jet pump, the jet pump include an injection pump housing, the injection pump housing be equipped with injection entrance, injection spout,
Pump housing oil inlet and pump housing oil outlet, the injection entrance and injection spout are interconnected, and the pump housing oil outlet is arranged
In the outside of injection spout, the pump housing oil inlet is arranged below injection spout, the pump housing oil inlet and the pump housing
Oil outlet connection；The oil spilling mouth of the fuel pump is connected to the injection entrance by pipe.
The beneficial effects of the utility model are: it is guided to the injection pump housing from the extra oil liquid that the oil spilling mouth of fuel pump flows out,
The high pressure oil formed in pipeline is projected from injection spout, since the oil flow projected from injection spout is big, is made around fluid
Negative pressure is formed, the oil liquid in automotive oil tank is driven to enter runner, mixed liquor is formed, flows out to assembly shell from pump housing oil outlet
It is interior, guarantee automotive oil tank under low oil level state, assembly shell is in full oil condition always, guarantees fuel oil pump assembly normally and efficiently
Operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the injection pump housing of the utility model；
Fig. 3 is the top view of Fig. 2.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown, a kind of fuel oil pump assembly with jet pump, including assembly shell 2 and fuel pump 1, fuel pump 1 are arranged
In assembly shell 2, the bottom of the assembly shell 2 is equipped with a jet pump 3, and the jet pump 3 includes an injection
The pump housing 4, the injection pump housing 4 is equipped with injection entrance 5, injection spout 7, pump housing oil inlet 8 and pump housing oil outlet 9, described
Injection entrance 5 and injection spout 7 be interconnected, the pump housing oil outlet 9 is set in the outside of injection spout 7, described
Pump housing oil inlet 8 is arranged below injection spout 7, and the pump housing oil inlet 8 is connected to pump housing oil outlet 9；The combustion
The oil spilling mouth 10 of oil pump 1 is connected to the injection entrance 5 by pipe 6.
A positioning sleeve 11 is additionally provided on the injection pump housing 3, the positioning sleeve 11 does positioning with fuel pump 1 and matches
It closes.
The pipe 6 is bellows.
