According to the oil filter with the bypass protection function, the oil return baffle is arranged between the filter element in the oil outlet and the bypass valve to settle the large particle impurities carried by engine oil and store the large particle impurities into the containing grooves; and because the filter element is arranged at the front end of the bypass valve, the impurities in the engine oil is further removed, and wear of the engine is reduced.
Description
Technical field
The present invention relates to engine oil filter for vehicle technical field, particularly relate to a kind of bypass protection oil filter.
Background technique
Oil filter, as parts of internal-combustion engine, plays a very important role in lubrication system.Motor can produce and be mixed into the contaminant filters such as the colloid that metal filings, carbon granules and machine oil in machine oil produces gradually by oil filter in combustion, to avoid wearing and tearing and the lubricating oil path blocking of these impurity accelerated motion parts, ensure that the normal operation of internal-combustion engine, the working life of internal-combustion engine is improved greatly, also can extend the working life of other component.
Existing oil filter, in order to consider motor at cold start-up engine oil viscosity large or paper filter element by Partial Blocking or all block time, the direct oil flow channel that guarantee machine oil energy smooth circulation postbacks motivation and designs, bypass valve is provided with on paper filter element side, when opening bypass valve under the pressure of machine oil at oil pump, the machine oil now looping back motor through bypass valve not only can not get the filtration of paper filter element, but also can by original by large granular impurity that paper filter element filters out, through bypass valve again refunds in motor, continual secondary is brought to wear and tear to motor.
Summary of the invention
In order to solve the technical problem existed in background technique, the present invention proposes a kind of bypass protection oil filter, avoiding the machine oil entering motor by bypass valve to carry large granular impurity and wearing and tearing are caused to motor.
A kind of bypass protection oil filter that the present invention proposes, comprising: filler opening, oil outlet, filter core, bleed off circuit, bypass valve, oil return baffle, containing groove, bypass filter core; Filler opening is positioned at oil filter top and is connected with oil pump; Oil outlet is positioned at oil filter bottom and is connected with motor; Filter core is arranged in oil outlet; Bleed off circuit is positioned at oil outlet side and is connected with motor; Bypass filter core is provided with after the bypass valve of bleed off circuit; Oil return baffle is arranged between oil outlet and bleed off circuit, and the lower surface of oil return baffle is outer arcuate, and the upper surface of oil return baffle is arc, arranges multiple large granular impurity to precipitation carry out accommodating containing groove at the upper surface of oil return baffle.
Preferably, bleed off circuit, is positioned on or below oil outlet.
Preferably, bottom oil filter, multiple receiving groove is set near the position of oil outlet, precipitation is carried out to the large granular impurity in backflow machine oil accommodating.
Preferably, receiving groove is that upper shed is greater than slot bottom width.
Preferably, bleed off circuit axis horizontal by a tilt angle, between 5 degree to 10 degree.
In the present invention, oil return baffle is set between oil outlet filter core and bypass valve, sedimentation is carried out to the large granular impurity that machine oil carries, and is stored in containing groove; And filter screen is set in bypass valve front end, further filtering is carried out to the impurity in machine oil, reduce the wearing and tearing to motor.

Fig. 2 is a kind of bypass protection oil filter structure figure that the embodiment of the present invention 2 proposes.
Reference character:
10, filler opening; 20, oil outlet; 30, filter core; 40, bleed off circuit; 50, bypass valve; 60, oil return baffle; 70, containing groove; 80, bypass filter core.
Embodiment
As shown in Figure 1, the embodiment of the present invention 1 proposes a kind of bypass protection oil filter, comprising: filler opening 10, oil outlet 20, filter core 30, bleed off circuit 40, bypass valve 50, oil return baffle 60, containing groove 70, bypass filter core 80;
Filler opening 10 is positioned at oil filter top and is connected with oil pump; Oil outlet 20 is positioned at oil filter bottom and is connected with motor; Filter core 30 is arranged in oil outlet 20; Bleed off circuit 40 is positioned on oil outlet 20 and is connected with motor; Oil return baffle 60 is arranged between oil outlet 20 and bleed off circuit 40, the lower surface of oil return baffle 60 is outer arcuate, the upper surface of oil return baffle 60 is arc, arranges multiple containing groove 70 at the upper surface of oil return baffle 60, for carrying out accommodating to the large granular impurity of precipitation; Bypass filter core 80 is provided with after the bypass valve 50 of bleed off circuit 40.
In the course of the work, the machine oil in oil pump is by filler opening 10 ingress engine oil rectifier, and the impurity being arranged in filter core 30 pairs of machine oil at oil outlet 20 place filters, and the bypass valve 50 now in bleed off circuit 40 cuts out, and machine oil enters motor from oil outlet 20, when after oil filter work a period of time, filter core 30 have accumulated a lot of impurity, cause machine oil unimpededly cannot enter motor by oil outlet, now bypass valve 50 is opened, machine oil is under the effect of oil pump, produce flowing shown in arrow in figure, the lower surface of machine oil and oil return baffle 60 impacts, bleed off circuit 40 is directed to afterwards by oil return baffle 60 upper surface, the large granular impurity now carried in machine oil precipitates in two stages, a part is back to bottom oil filter, a part is precipitated in containing groove 70, seldom enter bleed off circuit 40, partial impurities is had to enter in time, filter core 80 can be bypassed again filter, further filtering is carried out to the impurity in machine oil, reduce the wearing and tearing to motor.
As shown in Figure 2, the embodiment of the present invention 2 proposes a kind of bypass protection oil filter, and other parts are all identical with Fig. 1, and just bleed off circuit is positioned at below oil outlet.
Bottom oil filter, multiple receiving groove is set near the position of oil outlet 20, precipitation is carried out to the large granular impurity in backflow machine oil accommodating.For the ease of cleaning, receiving groove is that upper shed is greater than slot bottom width.
Bleed off circuit axis, horizontal by a tilt angle, between 5 degree to 10 degree, makes the large granular impurity in machine oil can not enter bleed off circuit under gravity further.
In the present invention, oil return baffle is set between oil outlet filter core and bypass valve, sedimentation is carried out to the large granular impurity that machine oil carries, and is stored in containing groove; And filter screen is set in bypass valve front end, further filtering is carried out to the impurity in machine oil, reduce the wearing and tearing to motor.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
