The beneficial effects of the utility model are that the low noise steady voltage type electricity after the improvement spouts the fuel pump assembly, has adopted the overhead stabiliser subassembly, contains pressure regulating valve to in order to inhale the sound material parcel, make the car noise reduce, wherein inhale the sound material and constitute by porous plastic filter paper, undertake again and filter fuel impurity and reduce the effect of fuel pulsation.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In this embodiment, this low noise voltage stabilization type electricity spouts fuel pump assembly, including electricity injection pump 1, oil storage bucket 2, top cap 3, stabiliser subassembly 4 and ejector pump 5, stabiliser subassembly 4 installs on top cap 3, ejector pump 5 and electricity injection pump 1 are joined in marriage in oil storage bucket 2, and 2 bottoms of oil storage bucket are equipped with the one-way inlet valve 6 of intercommunication oil tank, and electricity injection pump 1 is equipped with oil outlet pipe 7 intercommunication stabiliser subassembly 4's oil inlet through going out oil pipe, stabiliser subassembly 4 is equipped with out oil nozzle 8, stabiliser subassembly 4's shell is stainless steel to adopt laser welding shaping, contain pressure regulating valve 9 and filter core 10 in the stabiliser subassembly 4, the filter core 10 cladding is on stabiliser subassembly 4's shell inner wall, and filter core 10 comprises porous sound absorption plastic filter paper, the pressure release mouth of pressure regulating valve 9 communicates the nozzle of ejector pump 5 through returning oil pipe 11. Wherein, the electric injection pump 1 is communicated with the oil outlet pipe 7 and the pressure regulating valve 9 is communicated with the oil return pipe 11 by corrugated pipes respectively.
As a specific embodiment of further improvement, the oil storage barrel 2 is obliquely arranged, the oblique low end is a flat bottom, the one-way oil inlet valve 6 is arranged on the flat bottom, and an injection inlet matched with the injection pump 5 is further arranged on the flat bottom.
The utility model discloses an operating principle, in the one-way inlet valve 6 of fuel process 2 bottoms of oil storage bucket entered into oil storage bucket 2, 1 during operation of electric spray pump, the fuel sent to the pressure stabilizing valve subassembly through electric spray pump 1 in, through going out oil nozzle 8 at last, reachs the engine, because install pressure valve and filter core 10 in the stabiliser subassembly 4, filter core 10 is a porous sound plastics filter paper of inhaling, can absorb the fuel undulant, and then noise abatement and vibration. When the pressure of the fuel in the pressure stabilizing valve component reaches the working pressure of the pressure regulating valve 9, the pressure regulating valve 9 is opened, the fuel flows to the nozzle of the injection pump 5 through the oil return pipe 11, the injection pump 5 starts to work, and the fuel in the fuel tank is injected into the fuel storage barrel 2.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
