Background technology
In engine working process, the carbon distribution and gelatinous precipitate that are aoxidized under metal filings, dust, high temperature, water etc. are no
It is disconnected to be mixed into lubricating oil.The effect of filter is exactly to filter out these mechanical admixtures and colloid, keeps the cleaning of lubricating oil, extends it
Service life.Filter should have filtering ability strong, and circulating resistance is small, the performances such as service life length.
Existing oil filter is to intercept to filter out objectionable impurities in machine oil, filter paper by single paper filter element hole
The smaller filter effect of micropore it is better, but machine oil handling capacity is poorer.In actual use, also 40% objectionable impurities,
It cannot be effectively filtered out by paper filter element, in 40% impurity, since Ferromagnetic Impurities are relatively tiny and hard, so miscellaneous with ferromagnetism
Matter is in the majority, it is also just maximum to engine damage.The existing oil filter used is designed with bypass in the bottom of paper filter element
Valve, this is in design, in order to consider that engine is big or paper filter element is stifled by Partial Blocking or all in cold start-up engine oil viscosity
When plug, ensure the direct oil flow channel that machine oil energy smooth circulation postbacks motivation and designs.When machine oil is opened under the pressure of oil pump
When by-passing valve, the machine oil for being recycled back to engine through by-passing valve at this time not only cannot get the filtering of paper filter element, but also can will be original
The large granular impurity filtered out by paper filter element, through in by-passing valve again refunds to engine, being brought uninterruptedly to engine
Secondary abrasion, therefore the oil filter used on the market plays a role in filtering at all under specific condition, so at this time
Filtering efficiency is zero.
Therefore, a kind of simple in structure, reasonable design is produced, filtering efficiency is high, and the filter for reducing engine scuffing has
Extensive market prospects.

Be provided with filter core, filter cylinder be provided in filter core, isolating cylinder is provided in the shell, be provided on isolating cylinder isolation guide plate, on
Portion's slip ring, auxiliary oil filtering hole and bottom slip ring are provided with sealing ring in the slip ring of top, bottom bullet are provided with below the slip ring of bottom
Spring is provided with auxiliary filter in isolating cylinder.
The auxiliary filter includes auxiliary filter cylinder and auxiliary filter core, and the auxiliary filter core is sleeved on auxiliary filter cylinder
Outside, assist the top of filter cylinder to be connected with the bottom of the filter cylinder, the bottom of filter cylinder be provided with donkey check valve.
Magnet ring is provided at the top of the isolating cylinder, the magnet ring is the loop configuration made of magnetic material, magnet ring edge
Embedded in the inside of isolating cylinder.
The top of bottom slip ring and the bottom of isolating cylinder links into an integrated entity structure, and bottom slip ring can with the shell
It is slidably connected.
The seal ring set mounted in the outside of auxiliary cartridge top portion, the inside of the top slip ring and sealing ring it is outer
Side slidable connection, link into an integrated entity on the inside of the outside of top slip ring and isolating cylinder structure.
The auxiliary oil filtering hole is arranged on the isolating cylinder between top slip ring and bottom slip ring, and auxiliary oil filtering hole is logical
Hole.
The isolation guide plate is annular, and the structure that links into an integrated entity is isolated at the top of the outside and isolating cylinder of guide plate, described
The bottom of head cover be provided with seal groove, the seal groove is matched with guide plate is isolated.
The quantity of the magnet ring is 5, and top of 5 magnet rings on the inside of isolating cylinder is uniformly distributed.
At a distance from the width of the isolation guide plate is not less than on the inside of isolating cylinder on the outside of filter cylinder.
The technical solution of the utility model has following good effect：The utility model is simple in structure, reasonable design, filtering effect
Rate is high, can not only filter the large granular impurity in machine oil, while can metallic particles absorptive collection therein be avoided metal
Particle damages engine interior；When engine oil viscosity is big or filter core is by Partial Blocking or when all blocking, isolating cylinder and every
The impurity filtered out can be closed inside it from guide plate, the machine oil into filter can pass through on the outside of isolating cylinder, pass through
The filtering discharge for assisting filter core, not only avoids filtered machine oil and is expelled directly out and cause to wear to engine, avoid simultaneously
The large granular impurity outflow filtered out causes the blocking of auxiliary filter core.
