Abstract
A kind of fuel oil pump assembly induction apparatus of oil-leakage-prevention, including an injection pump housing and injection entrance, injection spout, pump housing oil inlet and pump housing oil outlet；Injection entrance and injection spout are interconnected, pump housing oil outlet is arranged on the jet direction of injection spout, pump housing oil inlet is arranged on the side of injection spout, pump housing oil inlet is connected to pump housing oil outlet, injection entrance is connected to by oil pipe with the oil spilling mouth of fuel pump, and the choked flow component for preventing oil liquid suck-back from flowing back is arranged in the injection inlet.The beneficial effects of the utility model are: due to being provided with the choked flow component for preventing oil liquid suck-back from flowing back in injection inlet, therefore, after cut-out of fuel pump, under the action of siphon principle, originally the oil liquid of meeting suck-back reflux is prevented by choked flow component, effectively prevent oil leak.
Description
Technical field
The utility model relates to the induction apparatus in a kind of vehicle fuel pump assembly more particularly to a kind of fuel oil pump assembly.
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.Under normal circumstances, oil liquid 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.In order to solve this problem, induction apparatus is provided in some fuel oil pump assemblies, the induction apparatus of the prior art includes one
The injection pump housing and injection entrance, injection spout, pump housing oil inlet and pump housing oil outlet；Injection entrance mutually connects with injection spout
Logical, pump housing oil outlet is arranged on the jet direction of injection spout, and pump housing oil inlet is arranged on the side of injection spout, the pump housing into
Hydraulic fluid port is connected to pump housing oil outlet, and injection entrance is connected to by oil pipe with the oil spilling mouth of fuel pump.Due to injection pipeline and fuel oil
Pump is directly connected to, and after cut-out of fuel pump, under the action of siphon principle, injection nozzle can generate a pressure
Difference makes the oil liquid suck-back in assembly shell return, causes oil leak.
Utility model content
The purpose of this utility model is exactly to overcome the deficiencies of the prior art and provide a kind of fuel pump that can effectively prevent oil leak
Assembly induction apparatus.
To achieve the goals above, the technical solution of the utility model is such that a kind of fuel pump of oil-leakage-prevention
Assembly induction apparatus, including an injection pump housing and injection entrance, injection spout, pump housing oil inlet and pump housing oil outlet；Draw
Entry portal and injection spout are interconnected, and pump housing oil outlet is arranged on the jet direction of injection spout, the setting of pump housing oil inlet
On the side of injection spout, pump housing oil inlet is connected to pump housing oil outlet, and injection entrance passes through the oil spilling mouth of oil pipe and fuel pump
The choked flow component for preventing oil liquid suck-back from flowing back is arranged in the injection inlet in connection.
The beneficial effects of the utility model are: due to being provided with the resistance for preventing oil liquid suck-back from flowing back in injection inlet
Component is flowed, therefore, after cut-out of fuel pump, under the action of siphon principle, originally the oil liquid of meeting suck-back reflux is by choked flow
Component prevents, and effectively prevent oil leak.
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 choked flow component of the utility model.
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 induction apparatus of oil-leakage-prevention, including an injection pump housing 5 and injection entrance
4, injection spout 3, pump housing oil inlet 10 and pump housing oil outlet 11；Injection entrance 4 and injection spout 3 are interconnected, and the pump housing is fuel-displaced
Mouth 11 is arranged on the jet direction of injection spout 3, and pump housing oil inlet 10 is arranged on the side of injection spout 3, pump housing oil inlet
10 are connected to pump housing oil outlet 11, and injection entrance 4 is connected to by oil pipe 1 with the oil spilling mouth of fuel pump 2, in the injection entrance
One choked flow component 12 for preventing oil liquid suck-back from flowing back is set at 4.
The choked flow component 12 includes choked flow set 6, choke plug 7, choked flow spring 8 and choked flow bracket 9, the choked flow set
6 are fixed with sealing with injection entrance 4, and the choke plug 7, choked flow spring 8 and choked flow bracket 9 are successively set on choked flow set
In 6, the oil inlet of the choke plug 7 and choked flow set 6 does one-way sealing cooperation.
The injection pump housing 5 is fixed at the bottom of assembly shell 13, the pump housing oil outlet 11 and total shelling
13 integrated setting of body, the pump housing oil inlet 10 is by the gap structure between the bottom and the injection pump housing 5 of pump housing oil outlet 11
At.
