Description
Technical field
The present invention relates to a kind of electric fuel punp that automobile uses, especially a kind of electric fuel punp oil return noise reduction pressure regulator
Component.
Background technique
Electric fuel punp mainly provides the fuel oil of certain pressure for automobile fuel injection system, currently, electronic both at home and abroad
Fuel oil pump assembly it is many kinds of.But all fuel pumps are at runtime, all exist fuel oil by pipeline, oil pump, pressure regulator valve and
When each components, due to pipeline variation, the variation of flow velocity and the collision of fuel oil and each side wall, biggish noise and vibration can be generated
Dynamic problem, to reduce the comfort used.
Such as: for electric fuel punp in operation, return flow oil passes through oil return pipe to pressure regulator, then arrives oil sump, the device
Including regulator base 1, the middle part of the regulator base 1 is provided with adjuster installation cavity 1a, and the two of the adjuster installation cavity 1a
Side is respectively oil inlet passage 1b and oil discharge passage 1c, and pressure regulator 3 is mounted in adjuster installation cavity 1a, and the pressure is adjusted
There is distance between 3 top jet of device and the top of adjuster installation cavity 1a, the lower end of the oil inlet passage 1b and pressure are adjusted
3 lower inlet of device is connected to, and the oil hole out being connected to oil discharge passage 1c, fuel oil are provided at the top of the adjuster installation cavity 1a
Enter oil inlet passage by oil pipe, then pass through pressure regulator, be emitted into linear state from the top export of pressure regulator,
It is easy to produce jet noise and vibration, influences comfort.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of electric fuel punp oil return that can reduce noise and vibration
Noise reduction pressure regulation device assembly.
Technical scheme is as follows: a kind of electric fuel punp oil return noise reduction pressure regulation device assembly, including regulator base, institute
It states and is provided with adjuster installation cavity in the middle part of regulator base, the two sides of the adjuster installation cavity are respectively oil inlet passage and fuel-displaced
Channel, pressure regulator are mounted in adjuster installation cavity, pressure regulator top oil outlet and adjuster installation cavity
There is distance between top, the lower end of the oil inlet passage is connected to pressure regulator lower inlet, the adjuster installation cavity
Top is equipped with the oil hole out being connected to oil discharge passage, it is characterised in that: the adjuster installation above the pressure regulator
It is intracavitary to be provided with lateral spoiler, several flow-disturbing holes are distributed on the transverse direction spoiler, the spoiler is located at oil hole
Lower section.
Using the above scheme, spoiler is set and becomes scattered by straight jet when oil return is sprayed from pressure regulator oil outlet
Jet stream, to play the effect for reducing jet noise.Fuel oil flows into oil discharge passage from oil hole out again after spoiler, most
After flow back to oil return pond.
In the above scheme: the spoiler is arranged in support tube.When installing in this way, first spoiler is packed into, is refilled
Pressure regulator, spoiler are arranged in support tube, facilitate installation.
In the above scheme: the support tube and spoiler are integrally formed.
The utility model has the advantages that the present invention is adjusted pressure by the way that spoiler is arranged in fuel pump pressure adjuster oil outlet upper end
The oil outlet oil spout state of device becomes scattering jet stream by straight jet and plays the effect of noise reduction to reduce jet noise and vibration
Fruit.Disturbing flow device install convenient of the invention, at low cost, effect is good.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
The top view of Fig. 2 spoiler.
Fig. 3 is the scheme of installation of spoiler and support tube.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
Embodiment 1:
