Abstract
The utility model relates to a vehicle fuel filter assembly which comprises a filter outer shell base, a paper filter element and a filter upper body, wherein the filter upper body is provided with an oil inlet and an oil outlet, a rubber sealing ring is embedded in an upper body cover, a central supporting pipe is arranged at the center of the bottom portion of the filter outer shell base, and threads are arranged on the central supporting pipe. The vehicle fuel filter assembly has the advantages of being simple in structure, reliable in connection, durable for a long time, convenient to dismantle and assemble and capable of being free from influence of regions, providing clean fuel without water and without impurities for an engine, protecting precise components of injection valves, cool starting valves and the like in an engine electronic fuel injection system, and improving performance of the engine.
Description
Technical field
The utility model relates to a kind of auto parts and components, specifically, relates to a kind of automobile fuel oil filter assembly.
Background technique
Fuel filter has diesel-oil filter, gasoline filter and rock gas filter cleaner three major types.Fuel filter is on the pipeline that is connected between fuel pump and the throttle valve body filler opening.The effect of fuel filter is that solid sundries such as being contained in iron oxide in the fuel oil, dust is removed, and prevents that oil-fired system from stopping up.Reduce mechanical wear, guarantee motor stable operation, improve reliability, prolong the working life of motor.The structure of fuel filter is to be made up of stainless support in an aluminum hull and one, at support efficient filter paper core is housed and forms, and folded filter paper becomes daisy_petal part shape, to increase circulation area.Because the electronic fuel injection engine filter cleaner often bears the fuel pressure of 200～300KPa, so general requirement of this filter cleaner compressive strength reaches more than the 500KPa.
Though existing fuel filter kind is a lot, their common shortcomings are: complexity simple in structure, connect reliably inadequately, and remove and install difficulty.
The model utility content
At above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and connects reliably, durable for a long time, removes and installs to safeguard easy automobile fuel oil filter assembly.
Technical solution adopted in the utility model is:
A kind of automobile fuel oil filter assembly, formed by filter housing base, papery filter core, filter cleaner upper body, described filter cleaner upper body is provided with filler opening and oil outlet, the upper body lid is embedded with rubber seal, the bottom center of filter housing base is provided with central support tube, and central support tube is provided with screw thread.
Described papery filter core adopts the diagonal angle to fold and forms, and it is provided with the ring end cap in two ends up and down.
Described outer casing base upper end-hole is provided with lower body seam and the lower body perpendicular end surface that cooperates with the outside thread of upper body lid center bolt.
The beneficial effect of the relative prior art of the utility model:
The utility model automobile fuel oil filter assembly; have simple in structure; connect reliable; durable for a long time; easy accessibility can not be subjected to regional impact, provides no moisture, pure clean fuel oil to motor; precision parts such as injection valve, cold start-up valve in the protection engine electric spray system, the performance of raising motor.

Embodiment
Followingly with reference to drawings and Examples the utility model is described in detail:
Accompanying drawing 1-5 as can be known, a kind of automobile fuel oil filter assembly, formed by filter housing base 1, papery filter core 8, filter cleaner upper body 7, described filter cleaner upper body 7 is provided with filler opening 3 and oil outlet 4, filter cleaner upper body 7 lids are embedded with rubber seal 25, the bottom center of filter housing base 1 is provided with central support tube 2, and central support tube 2 is provided with screw thread; Described papery filter core 8 adopts the diagonal angle to fold and forms, and it is provided with the ring end cap in two ends up and down; Described filter housing base 1 upper end-hole is provided with lower body seam 31 and the lower body perpendicular end surface 33 that cooperates with the outside thread of upper body lid center bolt 21, the outside thread cooperation of upper body lid center bolt 21 is tightened by certain moment of torsion with it, guaranteeing the filter cleaner good seal, and can conveniently remove and clean and renew cartridge more.
The effect of automobile filter is with the moisture in the fuel oil and impurity filtering.During engine operation, fuel oil enters in the center tube internal holes sediment bowl of filter cleaner through oil inlet pipe under the effect of petrol pump.Because this moment, volume became big, flow velocity diminishes, and than the bottom that the heavy water of oil and impurity particle just are deposited in cup, light impurity flows to filter core with fuel oil, and the fuel oil of cleaning oozes people's filter core from the micropore of filter core inside.In gasoline filter inside, the two ends of folding filter paper connect, and sump oil arrives the outward edge top by filter cleaner through after filter paper filters layer by layer after flowing into from filler opening 3, and clean fuel oil brings out hydraulic fluid port 4 outflows from the upper body lid.
The fuel filter assembly of band mounting bracket is the vitals on the automobile, and fuel oil can produce the accumulation of static in by filter cleaner, cause producing electric discharge phenomena, therefore must good grounded bracket and the function bonding end of design.Therefore shell aluminium matter metal shell and support thereof are fixed, and after smooth surface was handled, the outer surface plated film was prevented oxidation.The design of filler opening end has wire gaze, namely keeps inner support pipe aperture place oil circuit unimpeded, and the end cap silk screen adopts riveted formula end cap, and its thickness is 1mm.The papery filter core is by making through resin processed micropore filter paper, the filtering efficiency height, and with low cost, it is convenient to change.
The utlity model has easy accessibility; need not the specialized apparatus instrument, can not be subjected to regional impact, provide no moisture, pure clean fuel oil to motor; precision parts such as injection valve, cold start-up valve in the protection engine electric spray system, the performance of raising motor.
