Description
Technical field
The utility model is related to a kind of filter core and filter core associated component more particularly to a kind of automobile engine oil filter cores.
Background technology
Machine oil filter core is exactly oil filter, and the effect of oil filter is sundries, colloid and the moisture filtered out in machine oil,
Clean machine oil is conveyed to each lubricant housings, to reduce the frictional resistance in engine between relative motion parts, mitigates part
Abrasion, machine oil is constantly delivered to the friction surface of each moving parts, forms lubricating oil film, be lubricated.In machine oil in itself
Containing a certain amount of colloid, impurity, moisture and additive, while in engine working process, the bringing into of metal filings, air
Entrance, the generation of machine oil oxide of middle sundries so that the sundries in machine oil gradually increases.If machine oil is without filtering, directly
Into lubricant passage way, the sundries contained in machine oil will be brought into the friction surface of kinematic pair, accelerate the abrasion of part, reduced
The service life of engine.
Since machine oil viscosity itself is big, sundries content is higher in machine oil, and to improve filtering efficiency, oil filter generally has
Three-level is respectively sump strainer, primary oil filter and secondary oil filter.Collecting filter is in oil sump before lubricating oil pump, generally
Using metal screen formula.Primary oil filter is connected behind lubricating oil pump with main oil gallery, mainly there is metal Wiper blade type, sawdust filter
Core type, micropore filter paper type are several, primarily now using micropore filter paper type.Secondary oil filter is mounted in after lubricating oil pump with main oil gallery simultaneously
Connection, mainly there is two kinds of micropore filter paper type and rotator type.More common is micropore filter paper type machine oil filter core on the market, and such filter core leads to
Often it is cylindrical shape, is coated on central tube, after certain time length is reached, causes to filter since filter core adsorbs a large amount of impurity
It is ineffective, need replacing filter core at this time, because filter core is integral, during replacement can only integral replacing, the waste of material can be caused,
In addition, when filter core Severe blockage or the excessive too low viscosity of oil temperature, it will cause machine oil that cannot pass through from filter core other at this time
Port valve opening flows directly out machine oil, and the machine oil by filtering flows to position to be lubricated, and a large amount of impurity contained therein are by shadow
The friction surface of kinematic pair is rung, accelerates the abrasion of part, reduces the service life of engine.
The content of the invention
According to more than technical problem, the utility model provides a kind of automobile engine oil filter core, it is characterised in that including by-passing valve,
Spring, strainer, filter core, central tube, sealing ring, check-valves, shell, cover board, the by-passing valve are connected with spring, the spring one
End is equipped with strainer, and the spring is mounted on central tube one end, is cased with filter core outside the central tube, the filter core is divided into three
Point, first portion, second portion, Part III are followed successively by from the top down, and the first portion fits closely with second portion, institute
It states second portion to fit closely with Part III, the central tube other end is equipped with check-valves, the check-valves and central tube
Between be equipped with sealing ring, the check-valves is connected with cover board, and the outer cover suit is on the outside of filter core, the shell one side and cover board
Cooperation is concordant.
Micropore is distributed in the central tube side wall.
The strainer is made of disk and non-woven fabrics, and micropore is distributed on the disk, and the non-woven fabrics envelopes disk
Tow sides.
The cover board circumferentially has N number of fuel feed hole, N >=10, and oil outlet is equipped at the cover plate central
The beneficial effects of the utility model are：The utility model is automobile engine oil filter core, when filter core Severe blockage or machine
When the too low viscosity of oil temperature is excessive, machine oil will not pass through filter core, and by-passing valve is opened at this time, and machine oil flows directly out, because of this reality
Strainer is equipped with new, and strainer tow sides are coated with non-woven fabrics, machine oil can be carried out when machine oil can not pass through filter core
Filter avoids the abrasion that a large amount of impurity contained in machine oil treat lubricant housings, the movement pair surface of each component is protected to be allowed to
It is not damaged.The filter core of the utility model is divided into three parts, and when replacement only needs to change the first portion close to machine oil input end, will
Second portion moves up the position of the former first portion of substitution, Part III is moved up to the position of the former second portion of substitution, by new filter
Core is mounted on the position of former Part III, reduces the waste of material for core, filter is extended in the state of filter effect is ensured
The service life of core.

Specific embodiment
It is shown below in conjunction with the accompanying drawings, the utility model is further described：The utility model is automobile engine oil filter core
And element kit, including by-passing valve 1, spring 2, strainer 3, filter core 4, central tube 5, sealing ring 6, check-valves 7, shell 8, cover board 9,
By-passing valve 1 connects 2 with spring and connects, and 2 one end of spring is equipped with strainer 3, and strainer 3 is made of disk and non-woven fabrics, is distributed on disk
Micropore, non-woven fabrics envelope disk tow sides, and spring 2 is mounted on one end of central tube 5, and micropore is distributed in 5 side wall of central tube,
It is cased with filter core 4 outside central tube 5, filter core 4 divides for three parts, and 4 first portion of filter core is bonded with second portion, 4 second portion of filter core
It is bonded with Part III, 5 other end of central tube is equipped with check-valves 7, sealing ring 6 is equipped between check-valves 7 and central tube 5, only
It returns valve 7 to be connected with cover board 9, cover board 9 circumferentially has N number of fuel feed hole, N >=10, equipped with oil outlet, shell 8 at 9 center of cover board
4 outside of filter core is sleeved on, 8 one side of shell coordinates concordant with cover board 9.
When the utility model is used, under normal operating conditions, check-valves 7 is opened, and by-passing valve 1 is closed, and machine oil is from cover board 9
Fuel feed hole enter, by the filtering of filter core 4, through the micropore of 5 side wall of central tube, flowed out from the oil outlet of cover board 9, work as filter core
4 using needing replacing for a period of time when because machine oil reaches 4 other end of filter core from 4 one end of filter core, filter core 4 contacts machine oil at first
First portion block most serious, the second portion chocking-up degree backward that postpones is lighter than first portion, and Part III chocking-up degree is light
In second portion, so only needing to change the first portion of filter core 4, then the second portion of filter core 4 is moved up, substitution is first former
The position divided, 4 Part III of filter core is moved up, and substitutes the position of former second portion, and new filter core 4 is mounted on former Part III
Position, when arriving again at replacing construction, repeat above step, so operate 4 integral replacing of filter core need not be fallen, save
The material of filter core 4 avoids waste.When 4 Severe blockage of filter core without replacing in time or the too low viscosity of oil temperature
When excessive, machine oil will be unable to through filter core 4, and by-passing valve 1 is opened at this time, and machine oil is flowed out by by-passing valve 1, by strainer 3, strainer
3 tow sides are coated with non-woven fabrics, and strainer 3 and non-woven fabrics play a role in filtering, and avoid in machine oil contained a large amount of impurity to treating
The abrasion of lubricant housings protects the movement pair surface of each component to be allowed to not be damaged.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, several improvement can also be made, these, which are improved, also should
