Abstract

The invention relates to the transport and agricultural machinery industry, is intended for use in the purification of fuel in internal combustion engines and provides improved filtration quality and service life of the filter element. For this, the filter curtain is made in the form of coaxial outer, inner and intermediate split rings 5,6 and 7, respectively, installed with a gap relative to each other. The outer ring, as well as the inner ring, is made with one connector 9, and each intermediate ring has two connectors 10 and 11. In the zone of one of its connectors, the intermediate ring is connected to the adjacent female ring, and in the area of the other connector to the adjacent male ring. Terminals 9, 10, and 11 are located in mutually perpendicular planes. 1 hp f-ly, 2 ill.

The invention relates to the transport and agricultural machinery industry and is intended for the purification of liquids, in particular diesel fuel of an internal combustion engine.

The purpose of the invention is to improve the quality of filtration and the service life of the filter element.

FIG. 1 shows a filter element, a longitudinal section; in fig. 2

Under such cleaning conditions, there is such a distribution of sediments when the filter material is used completely. The conventionally solid arrow shows the direction of movement of the contaminated fuel, and the dotted arrow indicates the path of the cleaned filter, the curtain, the cross-section, of coolant fuel. During the operation of the filter, the filter element contains a closed element spontaneously occurs

Filter curtain 1 includes outer, inner and intermediate split rings 5-7, respectively, mounted relative to each other with gaps 8. The outer ring as well as the inner one with one connector 9, and each intermediate ring 7 has two connectors 10 and II and is connected in the area of one of the connectors with an adjacent female ring, and in the area of the other connector is connected to an adjacent snap-on ring.

The economic effect of using a filter element is achieved by increasing its service life and, accordingly, reducing operating costs.

Claims (2)

1. A filtering element containing a closed filtering curtain made in the form of coaxial outer, inner and intermediate split rings installed with a gap relative to each other, characterized in that, in order to improve the filtration quality and service life of the filtering element, n the inner rings are made with one connector, and each intermediate one with two connectors, while in the zone of one of its connectors the intermediate ring is connected For example, for the third from the outer edge of the intermediate ring 7, its connection with the female ring is made in the place of the connector 10, and with the male ring in the place of the connector 11. Connectors 9-II are located in mutually perpendicular planes. The filter element works as follows. During operation, contaminated 1. A filtering element containing a closed filtering curtain made in the form of coaxial outer, inner and intermediate split rings installed with a gap relative to each other, characterized in that, in order to improve the filtration quality and service life of the filtering element, n the inner rings are made with one connector, and each intermediate one with two connectors, while in the zone of one of its connectors the intermediate ring is connected fuel under pressure enters a filter35 with an adjacent female ring, and in and passes through the filter shade 1, the area of the other - with the male ring, i.e. its multiple partitions. Furs 2. The element of claim 1, which is different nical and other soils are uniform, so that the connectors are placed in mutually retained over the entire surface of the filter perpendicular planes. curtains and partially in the pores of the filtering material, and the purified fuel through the central exhaust channel 4 flows further into the engine cylinders. Under such cleaning conditions, there is such a distribution of sediments when the filter material is used completely. The conventionally solid arrow shows the direction of movement of the contaminated fuel, and the dotted arrow indicates the path of cleared fuel. During the operation of the filter element spontaneously occurs deposits and mechanical impurities present in the fuel, specific load is optimal, and its service life max. The economic effect of using a filter element is achieved by increasing its service life and, accordingly, reducing operating costs. Invention Formula load is optimal, and its service life 1. A filter element containing a closed filter curtain made in the form of coaxial outer, inner and intermediate split rings installed with a gap relative to each other, characterized in that, in order to improve the quality of filtration and the service life of the filter element, the inner rings are made with one connector, and each intermediate ring has two connectors, while the intermediate ring is connected in the area of one of its connectors
