Known oil purification filter (RU patent No. 2081675, B01D27 / 00, publ. 06/20/97), which is the closest technical solution to the proposed, taken as a prototype, containing a housing with anti-drain valve, filter elements of the first and second stages, connected in parallel with the second stage the bypass valve, the filter element of the first stage is made in the form of a perforated shell, covered on the outside with a filter material of volumetric filtration, in contact with a larger diameter surface through the filter material with the inside her body surface, the shroud has open slots from the stronger base for allowing deflection filter material under the influence of oil pressure and for the formation of the bypass passage gap for the oil. When clogging the 1st stage under an increasing pressure drop, the filter material moves away from the housing, forming bypass slots acting as an emergency valve. The second stage of oil purification is a corrugated curtain. At extreme conditions of the filter, an emergency valve is triggered; in this case, partially the oil enters the crude lubrication system. The proposed filter provides complete protection of the engine from ingress of coarse abrasive inclusions, neutralization of acids, which significantly increases the life of the engine. The shell is made with magnetic filler. in this filter, the first coarse stone stands before

the main filter element and works sequentially with it, i.e. acts as a pre-cleaner. If both cleaning stages become clogged or when the engine is started in the cold season, the system remains without a sufficient amount of lubricant, which reduces the reliability and service life of the filter.

The objective of the proposed technical solution is to increase the reliability and durability of the filter.

This is achieved by the fact that in the oil filter, which contains a housing, a filtering element for fine oil cleaning, a filtering element for rough oil cleaning, an anti-drainage, bypass and emergency bypass valve, a filtering element for rough oil cleaning and an emergency bypass valve are located behind the bypass valve, entering operation alternately, respectively, after clogging of the filtering element for fine oil purification and the filtering element for crude oil purification (u) and opening the bypass valve.

In addition, the oil filter element is connected to the seat of the emergency bypass valve.

In addition, the oil filter element is located inside the oil filter element.

4 In addition, the oil filter element is made of

metal mesh or polymer material.

In addition, a permanent magnetic element has been added to the oil filter.

In addition, a permanent magnetic element is located in the closed end part of the housing.

Figure 1 shows an example implementation of an oil filter. The oil purification filter contains a housing 1, a cover with an amplifier 2, an anti-drain 3 and an overflow valve 4, an overflow valve spring 5, an oil fine filter element 6, a coarse oil filter element 7, an emergency bypass valve 8 operating at filter extreme conditions. At the same time, the oil filter element 7 and the emergency bypass valve 8 are located behind the bypass valve 4, getting into operation one after the other, after clogging the oil filter element 6 and oil filter element 7 when the bypass valve 4 is opened.

The oil filter element 7 is tightly connected to the seat of the emergency valve 9 and is located inside the oil filter element 7.

The device operates as follows.

When the engine starts, oil through the inlet 1 is pumped into the filter, then, overcoming the force of elastic deformation of the anti-drain valve 3, enters the filter cavity. Further, after passing through the filter element of fine oil purification 6 and the hole 10, the purified oil is returned to the highway (Fig. 2).

When starting a cold engine or with a dirty oil fine filter element 6, the filter works as follows: the oil is pumped into the filter, then bypassing the oil fine filter element 6 and overcoming the elastic force of the calibrated spring bypass valve 5 passes through the oil filter element 7, holes 10 and returns to the highway, without leaving sludge in the area of clean oil (Fig. 3).

In the case of contamination of the filter element of crude oil cleaning 7 at a critical pressure drop, an emergency bypass valve 8 is triggered and the oil returns to the line (Fig. 4).

A significant difference of the proposed oil filter from the prototype is that in the prototype the first stage of crude oil purification is installed in front of the filter element of the second stage - fine oil purification and works sequentially with it, i.e. acts as a pre-cleaner. If both cleaning steps become clogged or at 6

7 starting the engine in the cold season, the system remains without sufficient

the amount of grease

In the proposed oil filter, the cleaning stages work mainly alternately. The second cleaning stage formed by the oil filter element 7, is located inside the first cleaning stage formed by the oil filter element 6 after the bypass valve and comes into operation when the oil filter element 6 is clogged, or when the engine starts in the cold season, those. when opening the bypass valve 4. As a result, the ingress of crude oil into the engine to a certain state in the engine is excluded.

Emergency bypass valve 8 is triggered in exceptional cases, under extreme conditions of the filter, namely when both stages of filter cleaning are clogged, while providing an engine lubrication system, protecting its parts from increased wear due to lack of lubrication.

The filter element of coarse oil cleaning 7 is made in the form of a polymer-reinforced metal mesh or polymer material, the mesh of the filter element of crude oil purification is made with a pore size of from 70 to 120 microns.

z.t.

In addition, a permanent magnetic element 11 is installed in the closed end part of the housing, providing additional

cleaning up.

Thus, the claimed technical solution provides increased reliability and service life of the filter.
